NAME
feh - image viewer and cataloguer
SYNOPSIS
feh [options] [files | directories | URLs ...]
VERSION
This manual documents feh 2.14
Compile-time switches: libcurl support enabled, Xinerama support enabled,
builtin EXIF support disabled
DESCRIPTION
feh is a mode-based image viewer. It is especially aimed at command line
users who need a fast image viewer without huge GUI dependencies, though
it can also be started by (graphical) file managers to view an image. By
default (unless arguments or a filelist are specified) feh displays all
files in the current directory.
feh supports filelists, various image sorting modes, image captions, HTTP
and more. Configurable keyboard shortcuts are used to control it; the
mouse is also supported, but only required for very few actions.
feh can also be used as wallpaper setter.
EXIF tags are supported either using exiv2 / exifgrep via --info (see the
USAGE EXAMPLES section), or by compiling feh with exif=1.
MODES
feh is based on various modes, which are selected at startup by command
line options.
Slideshow mode is the default. It opens one window and displays the
first image in it, the keyboard and mouse can be used to change slides
(images). In slideshow mode, images can be deleted either from the
filelist or from the disk, the new filelist can then be saved to the disk
and reopened at a later time. An image can also be read from stdin via
"feh -".
Montage mode forms a montage from the filelist. The resulting image can
be viewed or saved, and its size can be limited by height, width or both.
Index mode forms an index print from the filelist. Image thumbnails are
shown along with the filename, filesize and pixel size, printed using a
truetype font of your choice. The resulting image can be viewed or
saved, and its size can be limited by height, width or both.
Thumbnail mode is like index mode, but the mini-images are clickable and
open the selected image in a new window.
Multiwindow mode shows images in multiple windows, instead of as a
slideshow in one window. Don't use with a large filelist ;)
List mode doesn't display images. Outputs an ls - style listing of the
files in the filelist, including image info such as size, pixels, type,
etc. Customlist mode will display whatever image info you want, in the
format you choose.
feh can also list either all the loadable files in a filelist or all the
unloadable files. Useful for preening a directory.
SUPPORTED FORMATS
feh can open any format supported by Imlib2, most notably jpeg and png.
If the convert binary (supplied by ImageMagick) is available, it also has
limited support for many other filetypes, such as svg, xcf and otf. Use
--magick-timeout num with a non-negative value to enable it. For
animated images, only the first frame is shown.
OPTIONS
-A, --action [flag]action
Specify a shell command as an action to perform on the image. In
slideshow or multiwindow mode, the action will be run when the
action_0 key is pressed, in list mode, it will be run for each
file. In loadable/unloadable mode, it will be run for each
loadable/unloadable file, respectively. In thumbnail mode,
clicking on an image will cause the action to run instead of
opening the image.
If flag is ";", feh will reload the current image instead of
switching to the next one after executing the action.
The action will be executed by /bin/sh. Use format specifiers to
refer to image info. See FORMAT SPECIFIERS for examples. E.g.
"feh -A mv ~/images/%n *". In slideshow mode, the next image
will be shown after running the action, in multiwindow mode, the
window will be closed.
--action1 .. --action9
Extra actions which can be set and triggered using the
appropriate number key.
-Z, --auto-zoom
Zoom pictures to screen size in fullscreen / fixed geometry mode.
-x, --borderless
Create borderless windows.
-P, --cache-thumbnails
Enable thumbnail caching in ~/.thumbnails. Only works with
thumbnails <= 256x256 pixels.
-K, --caption-path path
Path to directory containing image captions. This turns on
caption viewing, and if captions are found in path, which is
relative to the directory of each image, they are overlayed on
the displayed image. E.g. with caption path "captions/", and
viewing image "images/foo.jpg", the caption will be looked for in
"images/captions/foo.jpg.txt".
-L, --customlist format
Don't display images, print image info according to format
instead. See FORMAT SPECIFIERS.
--cycle-once
Exit feh after one loop through the slideshow.
-G, --draw-actions
Draw the defined actions and what they do at the top-left of the
image.
--draw-exif
(only if compiled with exif=1) display some EXIF information in
the bottom left corner, similar to using --info with exiv2 /
exifgrep .
-d, --draw-filename
Draw the filename at the top-left of the image.
--draw-tinted
Show overlay texts (as created by --draw-filename et al) on a
semi-transparent background to improve their readability
-f, --filelist file
This option is similar to the playlists used by music software.
If file exists, it will be read for a list of files to load, in
the order they appear. The format is a list of image filenames,
absolute or relative to the current directory, one filename per
line.
If file doesn't exist, it will be created from the internal
filelist at the end of a viewing session. This is best used to
store the results of complex sorts (-Spixels for example) for
later viewing.
Any changes to the internal filelist (such as deleting a file or
it being pruned for being unloadable) will be saved to file when
feh exits. You can add files to filelists by specifying them on
the command line when also specifying the list.
If file is "-", feh will read the filelist from its standard
input.
-e, --font font
Set global font. Should be a truetype font, resident in the
current directory or the font directory, and should be defined in
the form fontname/points, like "myfont/12".
-C, --fontpath path
Specify path as extra directory in which to search for fonts; can
be used multiple times to add multiple paths.
--force-aliasing
Disable antialiasing for zooming, background setting etc.
-I, --fullindex
Same as index mode, but with additional information below the
thumbnails. Works just like "feh --index --index-info
"%n\n%S\n%wx%h"". Enables MONTAGE MODE OPTIONS.
Note: This option needs to load all images to calculate the
dimensions of the feh window, so when using it with many files it
will take a while before a feh window is visible. Use --preload
to get a progress bar.
-F, --fullscreen
Make the window fullscreen. Note that in this mode, large images
will always be scaled down to fit the screen, --zoom zoom only
affects smaller images and never scales larger than necessary to
fit the screen size. The only exception is a zoom of 100, in
which case images will always be shown at 100% zoom, no matter
their dimensions.
-g, --geometry [width x height] [+ x + y]
Limit (and don't change) the window size. Takes an X-style
geometry string like 640x480 with optional +x+y window offset.
Note that larger images will be zoomed out to fit, but you can
see them at 1:1 by clicking the zoom button. Note that this
option does not enforce the geometry, changing it by a tiling WM
or manually is still possible.
-Y, --hide-pointer
Hide the pointer (useful for slideshows).
-B, --image-bg style
Use style as background for transparent image parts and the like.
Accepted values: checks, white, black. The default for windowed
mode is checks, while fullscreen defaults to black.
-i, --index
Enable Index mode. Index mode is similar to montage mode, and
accepts the same options. It creates an index print of
thumbnails, printing the image name beneath each thumbnail.
Index mode enables certain other options, see INDEX MODE OPTIONS
and MONTAGE MODE OPTIONS.
--index-info format
Show image information based on format below thumbnails in index
/ thumbnail mode. See FORMAT SPECIFIERS. May contain newlines.
Note: If you specify image-related formats (such as %w or %s),
feh needs to load all images to calculate the dimensions of its
own window. So when using them with many files, it will take a
while before a feh window becomes visible. Use --preload to get
a progress bar.
--info [flag]commandline
Execute commandline and display its output in the bottom left
corner of the image. Can be used to display e.g. image
dimensions or EXIF information. Supports FORMAT SPECIFIERS. If
flag is set to ";", the output will not be displayed by default,
but has to be enabled by the toggle_info key.
-k, --keep-http
When viewing files using HTTP, feh normally deletes the local
copies after viewing, or, if caching, on exit. This option
prevents this so that you get to keep the local copies. They
will be in /tmp with "feh" in the name.
--keep-zoom-vp
When switching images, keep zoom and viewport settings (zoom
level and X, Y offsets)
-l, --list
Don't display images. Analyze them and display an ls(1) - style
listing. Useful in scripts to hunt out images of a certain
size/resolution/type etc.
-U, --loadable
Don't display images. Just print out their names if imlib2 can
successfully load them. Returns false if at least one image
failed to load.
--magick-timeout timeout
Stop trying to convert unloadable files after timeout seconds. A
negative value disables covert / magick support altogether, a
value of zero causes feh to try indefinitely. By default, magick
support is disabled.
--max-dimension width x height
Only show images with width <= width and height <= height. If
you only care about one parameter, set the other to 0 (or a
negative value).
-M, --menu-font font
Use font (truetype, with size, like "yudit/12") as menu font.
--min-dimension width x height
Only show images with width >= width and height >= height. If
you only care about one parameter, set the other to 0.
-m, --montage
Enable montage mode. Montage mode creates a new image consisting
of a grid of thumbnails of the images in the filelist. When
montage mode is selected, certain other options become available.
See MONTAGE MODE OPTIONS.
-w, --multiwindow
Disable slideshow mode. With this setting, instead of opening
multiple files in slideshow mode, multiple windows will be
opened; one per file.
--no-jump-on-resort
Don't jump to the first image after resorting the filelist.
-N, --no-menus
Don't load or show any menus.
--no-screen-clip
By default, window sizes are limited to the screen size. With
this option, windows will have the size of the image inside them.
Note that they may become very large this way, making them
unmanageable in certain window managers.
--no-xinerama
Disable Xinerama support. Only makes sense when you have
Xinerama support compiled in.
-j, --output-dir directory
Save files to directory (only useful with -k)
-p, --preload
Preload images. This doesn't mean hold them in RAM, it means run
through them and eliminate unloadable images first. Otherwise
they will be removed as you flick through. This also analyses
the images to get data for use in sorting, such as pixel size,
type etc. A preload run will be automatically performed if you
specify one of these sort modes.
-q, --quiet
Don't report non-fatal errors for failed loads. Verbose and
quiet modes are not mutually exclusive, the first controls
informational messages, the second only errors.
-z, --randomize
When viewing multiple files in a slideshow, randomize the file
list before displaying. The list is re-randomized whenever the
slideshow cycles (that is, transitions from last to first image).
-r, --recursive
Recursively expand any directories in the commandline arguments
to the content of those directories, all the way down to the
bottom level.
-R, --reload int
Reload filelist and current image after int seconds. Useful for
viewing HTTP webcams or frequently changing directories. (Note
that the filelist reloading is still experimental.)
If an image is removed, feh will either show the next one or
quit. However, if an image still exists, but can no longer be
loaded, feh will continue to try loading it.
-n, --reverse
Reverse the sort order. Use this to invert the order of the
filelist. E.g. to sort in reverse width order, use -nSwidth.
-., --scale-down
Scale images to fit window geometry (defaults to screen size when
no geometry was specified). This option is ignored when in
fullscreen mode.
In tiling environments, this also causes the image to be centered
in the window.
--scroll-step count
Scroll count pixels whenever scroll_up, scroll_down, scroll_left
or scroll_right is pressed. Note that this option accepts
negative numbers in case you need to inverse the scroll
direction; see KEYS CONFIG SYNTAX to change it permanently.
Default: 20
-D, --slideshow-delay float
For slideshow mode, wait float seconds between automatically
changing slides. Useful for presentations. Specify a negative
number to set the delay (which will then be float * (-1)), but
start feh in paused mode.
-S, --sort sort_type
The file list may be sorted according to image parameters.
Allowed sort types are: name, filename, mtime, width, height,
pixels, size, format. For sort modes other than name, filename,
or mtime, a preload run will be necessary, causing a delay
proportional to the number of images in the list.
The mtime sort mode sorts images by most recently modified. To
sort by oldest first, reverse the filelist with --reverse.
-|, --start-at filename
Start the filelist at filename. Note that at the moment,
filename must match an (expanded) path in the filelist. So, if
the file to be matched is passed via an absolute path in the
filelist, filename must be an absolute path. If the file is
passed via a relative path, filename must be an identical
relative path. This is a known issue. See also USAGE EXAMPLES.
-T, --theme theme
Load options from config file with name theme - see THEMES CONFIG
SYNTAX for more info. Note that commandline options always
override theme options. The theme can also be set via the
program name (e.g. with symlinks), so by default feh will look
for a "feh" theme.
-t, --thumbnails
Same as Index mode, but the thumbnails are clickable image
launchers. Note that --fullscreen and --scale-down do not affect
the thumbnail window. They do, however, work for image windows
launched from thumbnail mode. Also supports MONTAGE MODE
OPTIONS.
-~, --thumb-title string
Set title for windows opened from thumbnail mode. See also
FORMAT SPECIFIERS.
-^, --title title
Set window title. Applies to all windows except those opened
from thumbnail mode. See FORMAT SPECIFIERS.
-u, --unloadable
Don't display images. Just print out their names if imlib2 can
NOT successfully load them. Returns false if at least one image
was loadable.
-V, --verbose
output useful information, progress bars, etc.
-v, --version
output version information and exit.
--xinerama-index screen
Override feh's idea of the active Xinerama screen. May be useful
in certain circumstances where the window manager places the feh
window on Xinerama screen A while feh assumes that it will be
placed on screen B.
In background setting mode: When used with any option other than
--bg-tile: Only set wallpaper on screen. All other screens will
be filled black/white. This is most useful in a Xinerama
configuration with overlapping screens. For instance, assume you
have two overlapping displays (index 0 and 1), where index 0 is
smaller. To center a background on the display with index 0 and
fill the extra space on index 1 black/white, use
"--xinerama-index 0" when setting the wallpaper.
--zoom percent | max | fill
Zoom images by percent when in full screen mode or when window
geometry is fixed. When combined with --auto-zoom, zooming will
be limited to the specified percent. Specifying max is like
setting --auto-zoom, using fill makes feh zoom the image like the
--bg-fill mode.
MONTAGE MODE OPTIONS
These additional options can be used for index, montage and (partially)
thumbnail mode.
-a, --alpha int
When drawing thumbnails onto the background, set their
transparency level to int (0 - 255).
-b, --bg file | trans
Use file as background for your montage. With this option
specified, the montage size will default to the size of file if
no size restrictions were specified. Alternatively, if file is
"trans", the background will be made transparent.
-X, --ignore-aspect
By default, the montage thumbnails will retain their aspect
ratios, while fitting into thumb-width/-height. This options
forces them to be the size set by --thumb-width and
--thumb-height. This will prevent any empty space in the final
montage.
-H, --limit-height pixels
Limit the height of the montage.
-W, --limit-width pixels
Limit the width of the montage, defaults to 800 pixels.
If both --limit-width and --limit-height are specified, the
montage will be exactly width x height pixels in dimensions.
-o, --output file
Save the created montage to file.
-O, --output-only file
Just save the created montage to file without displaying it.
-s, --stretch
Normally, if an image is smaller than the specified thumbnail
size, it will not be enlarged. If this option is set, the image
will be scaled up to fit the thumbnail size. Aspect ratio will
be maintained unless --ignore-aspect is specified.
-E, --thumb-height pixels
Set thumbnail height.
-y, --thumb-width pixels
Set thumbnail width.
-J, --thumb-redraw n
Only relevant for --thumbnails: Redraw thumbnail window every n
images. In feh <= 1.5, the thumbnail image used to be redrawn
after every computed thumbnail (so, it updated immediately).
However, since the redrawing takes quite long (especially for
thumbnail mode on a large filelist), this turned out to be a
major performance penalty. As a workaround, the thumbnail image
is redrawn every 10th image now by default. Set n = 1 to get the
old behaviour, n = 0 will only redraw once all thumbnails are
loaded.
INDEX MODE OPTIONS
-@, --title-font font
Set font to print a title on the index, if no font is specified,
no title will be printed.
BACKGROUND SETTING
feh can also be used as a background setter. Unless you pass the
--no-fehbg option, it will write a script to set the current background
to ~/.fehbg. So to have your background restored every time you start X,
you can add "sh ~/.fehbg &" to your X startup script (such as
~/.xinitrc). As of feh 2.13, this script is executable, so "~/.fehbg &"
will work as well.
For the --bg-center and --bg-max options, you can use the --geometry
option to specify an offset from one side of the screen instead of
centering the image. Positive values will offset from the left/top side,
negative values from the bottom/right. +0 and -0 are both valid and
distinct values.
Note that all options except --bg-tile support Xinerama. For instance,
if you have multiple screens connected and use e.g. --bg-center, feh
will center or appropriately offset the image on each screen. You may
even specify more than one file, in that case, the first file is set on
screen 0, the second on screen 1, and so on.
Use --no-xinerama to treat the whole X display as one screen when setting
wallpapers. You may also use --xinerama-index to use feh as a background
setter for a specific screen.
--bg-center
Center the file on the background. If it is too small, it will
be surrounded by a black border
--bg-fill
Like --bg-scale, but preserves aspect ratio by zooming the image
until it fits. Either a horizontal or a vertical part of the
image will be cut off
--bg-max
Like --bg-fill, but scale the image to the maximum size that fits
the screen with black borders on one side.
--bg-scale
Fit the file into the background without repeating it, cutting
off stuff or using borders. But the aspect ratio is not
preserved either
--bg-tile
Tile (repeat) the image in case it is too small for the screen
--no-fehbg
Do not write a ~/.fehbg file

CONFIGURATION
feh has three config files: themes for theme definitions, keys for key
bindings and buttons for mouse button bindings. It will try to read them
from $XDG_CONFIG_HOME/feh/, which (when XDG_CONFIG_HOME is unset)
defaults to ~/.config/feh/. If the files are not found in that
directory, it will also try /etc/feh/.
All config files treat lines starting with a "#" character as comments.
Note that mid-line comments are not supported.
THEMES CONFIG SYNTAX
.config/feh/themes allows the naming of option groups, called themes.
It takes entries of the form "theme options ...", where theme is the name
of the entry and options are the options which will be applied when the
theme is used. Note that the options are not parsed by any shell.
Therefore, filename expansion ("*.jpg" and similar) is not supported.
Quoting with both single and double quotes works, though.
An example entry would be "imagemap -rVq --thumb-width 40 --thumb-height
30 --index-info '%n\n%wx%h'".
You can use this theme in two ways. Either call "feh -Timagemap *.jpg",
or create a symbolic link to feh with the name of the theme you want it
to use. For the example above, this would be "ln -s `which feh `
~/bin/imagemap". Now just run "imagemap *.jpg" to use these options.
Note that you can split a theme over several lines by placing a backslash
at the end of an unfinished line.
Command line options always override theme options.
KEYS CONFIG SYNTAX
.config/feh/keys defines key bindings. It has entries of the form
"action [key1 [key2 [key3]]]".
Each key is an X11 keysym name as shown by xev(1), like "Delete". It may
optionally start with modifiers for things like Control, in which case
key looks like mod-keysym (for example "C-Delete" for Ctrl+Delete or
"C-1-Delete" for Ctrl+Alt+Delete)
Available modifiers are C for Control, S for Shift and 1, 4 for Mod1 and
Mod4. To match an uppercase letter like "S" instead of "s", the Shift
modifier is not required.
Specifying an action without any keys unbinds it (i.e. the default
bindings are removed).
Note: Do not use the same keybinding for multiple actions. feh does not
check for conflicting bindings, so their behaviour is undefined. Either
unbind the unwanted action, or bind it to another unused key. The order
in which you bind / unbind does not matter, though.
For a list of the action names, see KEYS.
KEYS
In an image window, the following keys may be used (The strings in
[square brackets] are the config action names):
a [toggle_actions]
Toggle actions display (see --draw-actions)
A [toggle_aliasing]
Enable/Disable anti-aliasing
c [toggle_caption]
Caption entry mode. If --caption-path has been specified, then
this enables caption editing. The caption at the bottom of the
screen will turn yellow and can be edited. Hit return to confirm
and save the caption, or escape to cancel editing. Note that you
can insert an actual newline into the caption using
<CTRL+return>.
d [toggle_filenames]
Toggle filename display (see --draw-filename)
e [toggle_exif]
(only if compiled with exif=1) Toggle EXIF tag display
f [save_filelist]
Save the current filelist as "feh_PID_ID_filelist"
h [toggle_pause]
Pause/Continue the slideshow. When it is paused, it will not
automatically change slides based on --slideshow-delay.
i [toggle_info]
Toggle info display (see --info)
k [toggle_keep_vp]
Toggle zoom and viewport keeping. When enabled, feh will keep
zoom and X, Y offset when switching images.
m [toggle_menu]
Show menu. Use the arrow keys and return to select items,
<escape> to close the menu.
n, <Space>, <Right> [next_img]
Show next image. Selects the next image in thumbnail mode.
o [toggle_pointer]
Toggle pointer visibility
p, <Backspace>, <Left> [prev_img]
Show previous image. Selects the previous image in thumbnail
mode.
q, <Escape> [quit]
Quit feh
r [reload_image]
Reload current image. Useful for webcams
s [save_image]
Save the current image as "feh_PID_ID_FILENAME"
v [toggle_fullscreen]
Toggle fullscreen
w [size_to_image]
Change window size to fit current image size
x [close]
Close current window
z [jump_random]
Jump to a random position in the current filelist
<, > [orient_3, orient_1]
In place editing - rotate the images 90 degrees
(counter)clockwise. The rotation is lossless, but may create
artifacts in some image corners when used with JPEG images.
Rotating in the reverse direction will make them go away. See
jpegtran(1) for more about lossless JPEG rotation. Note:
jpegtran does not update EXIF orientation tags. However, feh
assumes that you use the feature to normalize image orientation
and want it to be displayed this way everywhere. After every
rotation, it will unconditionally set the EXIF orientation to 1
("0,0 is top left"). Should you need to reverse this, see
jpegexiforient(1).
_ [flip]
In place editing - vertical flip
| [mirror]
In place editing - horizontal flip. Again, see jpegtran(1) for
more information.
0 .. 9 [action_0 .. action_9]
Execute the corresponding action (0 = --action, 1 = --action1
etc.)
<Return> [action_0]
Run the command defined by --action
<home> [jump_first]
Show first image
<end> [jump_last]
Show last image
<page up> [jump_fwd]
Go forward ~5% of the filelist
<page down> [jump_back]
Go backward ~5% of the filelist
+ [reload_plus]
Increase reload delay by 1 second
- [reload_minus]
Decrease reload delay by 1 second

aliasing for performance reasons, hit the render key after
scrolling to antialias the image.
<Alt+Left [scroll_left_page]>
Scroll to the left by one page
<Alt+Right [scroll_right_page]>
Scroll to the right by one page
<Alt+Up [scroll_up_page]>

Highlight next menu item
<Left> [menu_parent]
Highlight parent menu item
<Right> [menu_child]
Highlight child menu item
<Return>, <Space> [menu_select]
Select highlighted menu item
BUTTONS CONFIG SYNTAX
.config/feh/buttons. This works like the keys config file: the entries
are of the form "action [binding]".
Each binding is a button name. It may optionally start with modifiers
for things like Control, in which case binding looks like mod-button (for
example C-1 for Ctrl + Left button).
Note: Do not use the same button for multiple actions. feh does not
check for conflicting bindings, so their behaviour is undefined. Either
unbind the unwanted action, or bind it to another unused button. The
order in which you bind / unbind does not matter, though.
For the available modifiers, see KEYS CONFIGURATION SYNTAX.
BUTTONS
In an image window, the following buttons may be used (The strings in
[square brackets] are the config action names):
[reload]
Reload current image
1 <left mouse button> [pan]
pan the current image
2 <middle mouse button> [zoom]
Zoom the current image
3 <right mouse button> [menu]
Toggle menu
4 <mousewheel down> [prev]
Show previous image
5 <mousewheel up> [next]
Show next image
Ctrl+1 [blur]
Blur current image
Ctrl+2 [rotate]
Rotate current image
unbound [zoom_in]
Zoom in
unbound [zoom_out]
Zoom out
MOUSE ACTIONS
Default Bindings: When viewing an image, mouse button 1 pans the image
(moves it around) or, when only clicked, moves to the next image
(slideshow mode only). Quick drags with less than 2px of movement per
axis will be treated as clicks to aid graphics tablet users. Mouse
button 2 zooms (click and drag left->right to zoom in, right->left to
zoom out, click once to restore zoom to 100%) and mouse button 3 opens
the menu.
CTRL+Button 1 blurs or sharpens the image (drag left to blur, right to
sharpen); CTRL+Button 2 rotates the image around the center point.
A note about pan and zoom modes: In pan mode, if you reach a window
border but haven't yet panned to the end of the image, feh will warp your
cursor to the opposite border so you can continue panning.
When clicking the zoom button and immediately releasing it, the image
will be back at 100% zoom. When clicking it and moving the mouse while
holding the button down, the zoom will be continued at the previous zoom
level. The zoom will always happen so that the pixel on which you
entered the zoom mode remains stationary. So, to enlarge a specific part
of an image, click the zoom button on that part.
SIGNALS
In slideshow mode, feh handles the following signals:
SIGUSR1
Switch to next image
SIGUSR2
Switch to previous image
USAGE EXAMPLES
Here are some examples of useful option combinations. See also:
<http://feh.finalrewind.org/examples/>
feh /opt/images
Show all images in /opt/images
feh -r /opt/images
Recursively show all images found in /opt/images and
subdirectories
feh -rSfilename /opt/images
Same as above, but sort by filename. By default, feh will show
files in the order it finds them on the hard disk, which is
usually somewhat random.
feh -t -Sfilename -E 128 -y 128 -W 1024 /opt/images
Show 128x128 pixel thumbnails, limit window width to 1024 pixels.
feh -t -Sfilename -E 128 -y 128 -W 1024 -P -C
/usr/share/fonts/truetype/ttf-dejavu/ -e DejaVuSans/8 /opt/images
Same as above, but enable thumbnail caching in ~/.thumbnails and
use a smaller font.
feh -irFarial/14 -O index.jpg /opt/images
Make an index print of /opt/images and all directories below it,
using 14 point Arial to write the image info under each
thumbnail. Save the image as index.jpg and don't display it,
just exit. Note that this even works without a running X server
feh --unloadable -r /opt/images
Print all unloadable images in /opt/images, recursively
feh -f by_width -S width --reverse --list .
Write a list of all images in the directory to by_width, sorted
by width (widest images first)
feh -w /opt/images/holidays
Open each image in /opt/images/holidays in its own window
feh -FD5 -Sname /opt/images/presentation
Show the images in .../presentation, sorted by name, in
fullscreen, automatically change to the next image after 5
seconds
feh -rSwidth -A "mv %F ~/images/%N" /opt/images
View all images in /opt/images and below, sorted by width, move
an image to ~/image/image_name when enter is pressed
feh --start-at ./foo.jpg .
View all images in the current directory, starting with foo.jpg.
All other images are still in the slideshow and can be viewed
normally
feh --start-at foo.jpg *
Same as above
feh --info "exifgrep '(Model|DateTimeOriginal|FNumber|ISO|Flash)' %F |
cut -d . -f 4-" .
Show some EXIF information, extracted by exifprobe/exifgrep
feh --action 'rm %F' -rl --max-dim 1000x800
Resursively remove all images with dimensions below or equal to
1000x800 pixels from the current directory.
TILING WINDOW MANAGERS
feh was created with a floating window layout in mind. However, as of
2.0.1, it has limited support for tiling window managers.
Specifically, the --scale-down and --auto-zoom options will detect a
tiling environment and scale the image up / down to the current window
size. Unfortunately, this causes every image to be rendered twice: First
in a normal fashion, and then (after noticing that the window is being
tiled) again with the correct zoom level.
This is a known bug and will hopefully get fixed some time. For now, it
can be avoided by using --geometry 500x500 (or any other geometry). This
will have the same behaviour as --scale-down, but without the flickering.
DEPENDENCIES
feh requires the jpegtran and jpegexiforient binaries (usually
distributed in "libjpeg-progs" or similar) for lossless rotation.
To view images from URLs such as http://, you need feh compiled with
libcurl support (enabled by default). See the VERSION section.
BUGS
Thumbnail mode is somewhat inefficient, and because of that not nearly as
fast as it could be.
--scale-down does not take window decorations into account and may
therefore make the window slightly too large.
REPORTING BUGS
If you find a bug, please report it to <derf+feh@finalrewind.org> or via
<http://github.com/derf/feh/issues>. You are also welcome to direct any
feh-related comments/questions/... to #feh on irc.oftc.net.
Please include the feh version <the output of "feh --version">, steps to
reproduce the bug and, if necessary, images to reproduce it.
FUTURE PLANS
Plans for the following releases:
* Make zoom options more intuitive
