shed(1)shed(1)NAMEshed (Simple Hex EDitor)
SYNOPSISshed [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 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.
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 tradi‐
tional)
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
