2005-11-16Disallow empty pattern in "git grep"Libravatar Linus Torvalds1-0/+4
For some reason I've done a "git grep" twice with no pattern, which is really irritating, since it just grep everything. If I actually wanted that, I could do "git grep ^" or something. So add a "usage" message if the pattern is empty. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-24git-grep: fix 'git grep -e $pattern' handlingLibravatar Junio C Hamano1-1/+1
People typically say 'grep -e $pattern' because $pattern has a leading dash which would be mistaken as a grep flag. Make sure we pass -e in front of $pattern when we invoke grep. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-12Improve "git grep" flags handlingLibravatar Linus Torvalds1-23/+41
This allows any arbitrary flags to "grep", and knows about the few special grep flags that take an argument too. It also allows some flags for git-ls-files, although their usefulness is questionable. With this, something line git grep -w -1 pattern works, without the script enumerating every possible flag. [jc: this is the version Linus sent out after I showed him a barf-o-meter test version that avoids shell arrays. He must have typed this version blindly, since he said: I'm not barfing, but that's probably because my brain just shut down and is desperately trying to gouge my eyes out with a spoon. I slightly fixed it to catch the remaining arguments meant to be given git-ls-files.] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-09-12[PATCH] Add "git grep" helperLibravatar Linus Torvalds1-0/+20
Very convenient shorthand for git-ls-files [file-patterns] | xargs grep <pattern> which I tend to do all the time. Yes, it's trivial, but it's really nice. I can do git grep '\<some_variable\>' arch/i386 include/asm-i386 and it does exactly what you'd think it does. And since it just uses the normal git-ls-files file patterns, you can do things like git grep something 'include/*.h' and it will search all header files under the include/ subdirectory.
