2
3Shed is a program for viewing and editing non-text
4files. The look and feel is designed to be similar
5to that of pico's.

11USAGE
12****************************************************
13BACKUP YOUR FILES FIRST!!!.
14NB: Notice there is no save key. This is because the
15file is not loaded into memory, so when you edit it,
16the change is made directly to disk.
17****************************************************
18
19Type shed and a filename. If you're editing a file it
20must be an existing file. If no filename is given,
21or it is '-', then shed displays stdin.
22
23The man page has information on command line options.
24
25Each line of the shed display represents one byte of the
26file. Each lines consists of the offset of that byte from
27the start of the file, the ascii value of the byte, and
28then the bytes value in various bases. All values are
29unsigned.
30
31Keys:
32
33arrow keys - move cursor around
34pgup/^Y - cursor up 16
35pgdown/^V - cursor down 16
36home/^A - start of line
37end/^E - end of line
38
39space/e - edit value of current byte.
40 You are asked to enter the new value in the format of the current
41 column the cursor is in - eg. if you are in the hex column, it will
42 ask for the new value in hex.
43
441,2,4 - set size of cursor in bytes, in the hex/dec/oct columns (and binary
45 if in traditional mode).
46
47` - toggle the endianness of multi-byte values (when cursor size is 2 or 4)
48
49s, w, ^x, f, F3 - search.
50 Search string is asked for in the format of the current cursor column.
51 In ascii, just enter the string in ascii. In the others, enter the values
52 seperated by spaces - eg to search for ABC from the decimal column you
53 would enter "65 66 67" (without the quotes).
54
55^f,^b - search shortcut for forwards/backwards respectivly.
56
57r,n,F3 - repeat previous search
58
59t - toggle whether offset numbers and cursor position etc are in dec or hex.
60
61b - toggle binary mode column behaviour (bit edit mode vs traditional)
62
63d - dump to file.
64
65j - jump to byte. enter a byte number, or 'top' or 'end'.
66
67a - change the mode of the ascii column (printable only/c-style extended chars/'man ascii' descriptions)
68
69p - turn on 'preview' mode.
70
71x, ^x - exit
72
73
74When a command (except search) asks you for input, entering a
75zero-length string will cancel the command, as will ^C.
76When searching, entering a zero-length string will use the
77previous search word, if one exists.

79NOTES
80shed can be used directly on devices (/dev/*) but it can not
81obtain the length so you can overrun the length of the device.
