Subject: grep-find with camelCase returns error of 123
--text follows this line--
this is possibly a bug.
Summary: when using M-x grep-find, on a search word with camelCase, i
get this error:
“Grep exited abnormally with code 123 at Mon Mar 16 17:22:46”.
Reproduce steps:
• start emacs 22.x with -q
• M-x grep-find
• Try to search a word with camelCase. e.g. “find . -name "*txt" -
print0 | xargs -0 -e grep -nH -e pestiLence”
• Emacs gives the error mentioned above.
This is reproducible in:
• GNU Emacs 22.2.1 (powerpc-apple-darwin8.11.0, Carbon Version
1.6.0) of 2008-04-05 on g5.tokyo.stp.isas.jaxa.jp
• GNU Emacs 22.0.50.1 (powerpc-apple-darwin8.11.0, GTK+ Version
2.6.10) of 2009-03-01 on xahg5.local
This problem happens also when called with shell-command. e.g. M-x
shell-command, then use
“find . -name "*txt" -print0 | xargs -0 -e grep -nH -e pestiLence”.
However, this does not happen when called in shell, e.g. M-x shell.
Nor when i simply run it in a Terminal running bash. (so, prob not
having to do with the unix's “find”, “grep”, “xargs”
programs on my computer.)

This is not surprising, since 123 is xargs' exit code if any of the
command invocations failed, see the "EXIT STATUS" section in xargs(1).

Your shell may not report failure, but unless one of your files contains
pestiLence, the above command will still finish with an exit code of
123. Type "echo $?" to convince yourself.
Maybe it would be possible to special-case an exit code of 123 in
grep-find, but the problem is that this exit code does not tell if there
were matches or not.

Where did this come from? The version number suggests a CVS checkout,
but CVS hasn't been at 22.0.50 since 2006.
