NAME

       shed - simple hex editor with a pico-style interface

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  separated 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
