How to find a commit that introduces (not removes) a string?

How to find a commit that introduces (not removes) a string?

[Sebastian Schuberth]

Hi all,

I know about git log's -S / -G, but I'm unable to make these search through *introduced* strings only. Is there a way to do so?

Thanks!

PS: I also read [1], but although the author claims to be interested in introduced strings only, he seems to be satisfied with -G, which slightly puzzles me.

If you are using linux, here is git diff command I use to find leftover 
debug statements.  I imagine the -S option will work the same in git 
log.  I pipe the results into grep to filter the results to show only 
the additions. (I'm using git 1.7.1)

$ git diff --unified=0 -S"DEBUG" <commit> <commit> -- <path> | grep -e 
"diff --" -e "+" | grep -v -e "@@" -e "+++"

maybe you will find this helpful.

v/r,

This appears to work:

$ for ref in `git log -SWORD --pretty=format:"%h"` ; do 
    git log -1 -p $ref | grep WORD | grep -E '^[+]' > /dev/null ; 
    if [ $? -eq 0 ]; then 
        echo $ref; 
    fi ;
  done

substitute WORD for what you're looking for.  Note that it is repeated
twice.

Thanks for your suggestions. However, I ended up simply doing

$ git diff --no-color FROM..TO | grep ^+[^+] | grep WORD

which works well for my case.
