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
