NAME

       shed (Simple Hex EDitor)


SYNOPSIS

       shed [OPTIONS] [FILE]


DESCRIPTION

       A simple hex editor with a pico-style interface.

       Each line of the shed display represents one byte of the file. Each
       lines consists of the offset of that byte from the start of the file,
       the ascii value of the byte, and then the byte's value in various
       bases. All values are unsigned.

       When a command asks you for input, entering a zero-length string or
       pressing ^C will cancel the command.  When searching, entering a zero-
       length string will use the previous search word, if one exists.

       Note that there is no save key. This is because the file is not loaded
       into memory, so when you edit it the change is made directly to disk.


OPTIONS

       -r / --readonly
              open FILE read only

       -s / --start=OFFSET
              position cursor to offset

       -H / --hex
              start in hex mode (hex offsets etc.)

       -L / --length=LENGTH
              set length of file to LENGTH. Useful for special files where
              shed cannot obtain the length with stat.

       -h / --help
              show help and exit

       -v / --version
              show version and exit


KEYS

       arrow keys
              move cursor around

       pgup / ^Y
              cursor up 16 pgdown / ^V cursor down 16

       home / ^A
              start of line (ascii column)

       end / ^E
              end of line (binary column)

       space / e
              edit value at cursor. You are asked to enter the new value in
              the format of the current column the cursor is in - eg. if you
              are in the hex column, it will ask for the new value in hex.

       1 / 2 / 4
              set size of cursor in bytes, in the hex/dec/oct columns (and
              binary if in traditional mode).

       ` (backtick)
              toggle the endianness of multi-byte values (when cursor size is
              2 or 4)

       s / w / ^w / f / F3
              search. Search string is asked for in the format of the current
              cursor column.  In ascii, just enter the string in ascii. In the
              others, enter the values  seperated by spaces.  eg to search for
              ABC from the decimal column you would enter "65 66 67" (without
              the quotes).

       ^f / ^b
              search shortcut for forwards/backwards respectivly.

       r / n / F3
              repeat previous search

       t      toggle whether offset numbers and cursor position etc are in dec
              or hex.

       b      toggle binary mode column behaviour (bit edit mode vs
              traditional)

       d      dump to file.

       j      jump to byte. enter a byte number, or 'top' or 'end'. Can be
              suffixed with K, M or G.

       a      change the mode of the ascii column (printable only/c-style
              extended chars/'man ascii' descriptions)

       p      toggle 'preview' mode.

       x / ^x exit
