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  press-
     ing  ^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 cur-
	    sor column.  In ascii, just enter the string in ascii. In  the  oth-
	    ers,  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  suf-
	    fixed 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
