Find out when a line was introduced or deleted in GIT history

Hi!

Did you ever come across a line of code that you d *really* like to know when was introduced/deleted ?

Well, if you are using GIT for your project this might come handy.

Let's say the piece of text you are investigating is this:

a = get_something(some_var)

and it is located in the file some_folder/some_file.py

Then, try this command:

git log -S "a = get_something(some_var)" some_folder/some_file.py

Then, GIT will look for the string we specified string within the commit history and output something like this:

commit
Author: Some Dude <some.dude@mail.com>
Date:   Fri Feb 15 14:09:18 2013 -0300
    The commit message of this commit.

This came quite handy to me recently. Hope it helps!

Happy programmer's day!

A man flying in a hot air balloon suddenly realizes he’s lost. He reduces height and spots a man down below. He lowers the balloon further and shouts to get directions, "Excuse me, can you tell me where I am?"

The man below says: "Yes. You're in a hot air balloon, hovering 30 feet above this field."

"You must work in Information Technology," says the balloonist.

"I do" replies the man. "How did you know?"

"Well," says the balloonist, "everything you have told me is technically correct, but It's of no use to anyone."

The man below replies, "You must work in management."

"I do," replies the balloonist, "But how'd you know?"*

"Well", says the man, "you don’t know where you are or where you’re going, but you expect me to be able to help. You’re in the same position you were before we met, but now it’s my fault."
