Find where code was deleted in a Git repository

git

Solution

Hmph, this works for me:

$ git init
Initialized empty Git repository in /Users/pknotz/foo/.git/

$ echo "Hello" > a

$ git add a

$ git commit -am "initial commit"
[master (root-commit) 7e52a51] initial commit
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 a

$ echo " World" >> a

$ git commit -am "Be more specific"
[master 080e9fe] Be more specific
 1 files changed, 1 insertions(+), 0 deletions(-)

$ echo "Hello" > a

$ git commit -am "Be less specific"
[master 00f3fd0] Be less specific
 1 files changed, 0 insertions(+), 1 deletions(-)

$ cat a
Hello

$ git log -SWorld

    Be more specific

Or, is this not what you mean?

Problem

How do I find code that was deleted? I ended up finding where it was created with this: ``` $ git log --pretty=oneline -S'some code' ``` And that's good enough, but I was also curious to find where it got deleted, and so far, no dice. First, I tried `git diff HEAD..HEAD^ | grep 'some code'`, expanding the range each time, until I found the lines where it was removed. Nice, so suppose I found it on range `HEAD^^..HEAD^^^`, then I do `git show HEAD^^^` and `git show HEAD^^` with `grep`, but the code is nowhere to be found! Then I read up a bit on `git bisect`, and sure enough, it gives me a single revision where the culprit is supposed to be... Again, `git show rev | grep 'some code'` comes up empty... What am I doing wrong?
