shed - simple hex editor with a pico-style interface
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.
- 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
