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

  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.

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