NAME
lookat - Un*x file viewer
SYNOPSIS
lookat [ --help ] [ filename ] [ dir_name ]
DESCRIPTION
"lookat" (or "bekijk" in the Dutch version) is a program to view Un*x
text files and manual pages.
Under DOS I used list.com to view text files. I didn't find such a
program under my favorite OS, GNU/Linux. The standard Un*x utilities (
more, less, view ...) weren't userfriendly enough. For this reason I
created "lookat".
OPTIONS
--help
This option displays a help text.
file_name
view file_name
dir_name
change the current directory to dir_name
BUGS
None known yet, when you find one you let me know :-)
USAGE
There are four ways to start lookat :
* by just typing 'lookat', after the program is started you can select
the file you want to view.
if there is already data on stdin, lookat will read the from stdin, and
display the contents of stdin
example:
ls | lookat
* type 'lookat dir_name', change the current directory to dir_name.
When the program is started you can select the file you want to view.
* by typing 'lookat <filename>', the file with <filename> will
automatically be loaded.
* in combination with "man"
examples :
man -Plookat ls
export PAGER=lookat; man ls
If you like "lookat" as your manual page viewer you can put the next
lines in your /etc/profile
alias man="man -Plookat"
After you have loaded a file, the following keys can be used:

of the window you get the files of the current directory. By

CONFIGURATION
Note:
The format of the configuration file has changed, please remove
the "=" sign. The old configuration files will still work, but
may not be supported in the future.
lookat uses two configuration files a global configuration file (
/usr/local/etc/lookat.conf ) and a user configuration file (
$HOME/.lookat ) if the user's configuration file exists the global is
ignored.
If the configuration files aren't available the defaults are used.
CONFIGURATION DIRECTIVES
cursor on|off
turn the cursor on / off
give_notice on|of
give notice on exit on / off
.[extension] "external cmd"
create a new type
If a filename matches a type the external command will be used
to open the file. A typical usage are gzipped files:
.gz "gzip -cd"
The type order is important lookat will compare the filename
with the types starting with the first type and continues until
a type matches a filename.
So if you want to define a type for ".gz" and ".tar.gz" files
you have to put the .tar.gz type first.
color object foreground background [ attribute ]
If your terminal supports colors, this directive can be use to
modify the color of certain objects. Valid objects are: view,
view_bold, view_italic, main_menu, main_menusel, main_menuhot,
main_menuhotsel, status_bar, win1, win1_edit, win1_menu,
win1_menusel, win1_menuhot, win1_menuhotsel, win2, win2_edit,
win2_menu, win2_menusel, win2_menuhot, win2_menuhotsel,
view_found.
Valid colors are: white, black, green, magenta, blue, cyan,
yellow, red.
Valid attributes are: normal, bold, underline, reverse, and
standout.
mono object foreground_attribute [ background_attribute ]
If your terminal doesn't support color, you can still assign
foreground and background attributes to certain objects.
