Revision 1.7, Sun Dec 30 08:17:32 2001 UTC (22 years, 5 months ago) by pvalchev
Branch: MAIN
Changes since 1.6: +8 -5 lines
Changes come from NetBSD, Lite-2 and me. ok deraadt
od(1):
- Enable support for printing 8-byte integers.
- Added -C option for hexadecimal+ASCII display.
- Fix od so it displays short files containing nulls.
- POSIXification: The C, S, I and L modifiers now behave correctly,
specifying output in units of a char, short, int and long (as defined by
the host system) respectively. Support -N, equivalent to hexdump's
-n (format only COUNT bytes of input). Add -j option which does the
same thing as -s in hexdump (skipping some of the input).
hexdump(1):
- POSIX.2 doesn't specify hexdump so it can't be compatible with it...
- add missing trailing \n in usage() printf
