1 /* xxd: my hexdump facility. jw
|
|
|
2 *
|
|
|
3 * 2.10.90 changed to word output
|
|
|
4 * 3.03.93 new indent style, dumb bug inserted and fixed.
|
|
|
5 * -c option, mls
|
|
|
6 * 26.04.94 better option parser, -ps, -l, -s added.
|
|
|
7 * 1.07.94 -r badly needs - as input file. Per default autoskip over
|
|
|
8 * consequtive lines of zeroes, as unix od does.
|
|
|
9 * -a shows them too.
|
|
|
10 * -i dump as c-style #include "file.h"
|
|
|
11 * 1.11.95 if "xxd -i" knows the filename, an 'unsigned char filename_bits[]'
|
|
|
12 * array is written in correct c-syntax.
|
|
|
13 * -s improved, now defaults to absolute seek, relative requires a '+'.
|
|
|
14 * -r improved, now -r -s -0x... is supported.
|
|
|
15 * change/suppress leading '\0' bytes.
|
|
|
16 * -l n improved: stops exactly after n bytes.
|
|
|
17 * -r improved, better handling of partial lines with trailing garbage.
|
|
|
18 * -r improved, now -r -p works again!
|
|
|
19 * -r improved, less flushing, much faster now! (that was silly)
|
|
|
20 * 3.04.96 Per repeated request of a single person: autoskip defaults to off.
|
|
|
21 * 15.05.96 -v added. They want to know the version.
|
|
|
22 * -a fixed, to show last line inf file ends in all zeros.
|
|
|
23 * -u added: Print upper case hex-letters, as preferred by unix bc.
|
|
|
24 * -h added to usage message. Usage message extended.
|
|
|
25 * Now using outfile if specified even in normal mode, aehem.
|
|
|
26 * No longer mixing of ints and longs. May help doze people.
|
|
|
27 * Added binify ioctl for same reason. (Enough Doze stress for 1996!)
|
|
|
28 * 16.05.96 -p improved, removed occasional superfluous linefeed.
|
|
|
29 * 20.05.96 -l 0 fixed. tried to read anyway.
|
|
|
30 * 21.05.96 -i fixed. now honours -u, and prepends __ to numeric filenames.
|
|
|
31 * compile -DWIN32 for NT or W95. George V. Reilly, * -v improved :-)
|
|
|
32 * support --gnuish-longhorn-options
|
|
|
33 * 25.05.96 MAC support added: CodeWarrior already uses ``outline'' in Types.h
|
|
|
34 * which is included by MacHeaders (Axel Kielhorn). Renamed to
|
|
|
35 * xxdline().
|
|
|
36 * 7.06.96 -i printed 'int' instead of 'char'. *blush*
|
|
|
37 * added Bram's OS2 ifdefs...
|
|
|
38 * 18.07.96 gcc -Wall @ SunOS4 is now slient.
|
|
|
39 * Added osver for MSDOS/DJGPP/WIN32.
|
|
|
40 * 29.08.96 Added size_t to strncmp() for Amiga.
|
|
|
41 * 24.03.97 Windows NT support (Phil Hanna). Clean exit for Amiga WB (Bram)
|
|
|
42 * 02.04.97 Added -E option, to have EBCDIC translation instead of ASCII
|
|
216
|
43 * (azc10@yahoo.com)
|
|
7
|
44 * 22.05.97 added -g (group octets) option (jcook@namerica.kla.com).
|
|
|
45 * 23.09.98 nasty -p -r misfeature fixed: slightly wrong output, when -c was
|
|
|
46 * missing or wrong.
|
|
|
47 * 26.09.98 Fixed: 'xxd -i infile outfile' did not truncate outfile.
|
|
|
48 * 27.10.98 Fixed: -g option parser required blank.
|
|
|
49 * option -b added: 01000101 binary output in normal format.
|
|
|
50 * 16.05.00 Added VAXC changes by Stephen P. Wall
|
|
|
51 * 16.05.00 Improved MMS file and merege for VMS by Zoltan Arpadffy
|
|
|
52 *
|
|
|
53 * (c) 1990-1998 by Juergen Weigert (jnweiger@informatik.uni-erlangen.de)
|
|
|
54 *
|
|
|
55 * Small changes made afterwards by Bram Moolenaar et al.
|
|
|
56 *
|
|
|
57 * Distribute freely and credit me,
|
|
|
58 * make money and share with me,
|
|
|
59 * lose money and don't ask me.
