Git: grep file in all previous versions

Question

Consider a Python configuration file with the following line:

THEME = 'gum'

The key THEMEappears only once, so when I want to know what it is THEME, I grep the file:

grep THEME pelicanconf.py

The file is stored in git, and I would like to grep for THEMEin all previous git commits to find out when this line was changed.

Is there an elegant way to grep the entire history of a git file?

Answer 1

git log -S'THEME' -- pelicanconf.py | xargs -n 1 git show shows the contents of each commit that changed THEME

However, it prints full commits, not just changes.

var="THEME"; git log -S"$var" -p -- pelicanconf.py | egrep "$var|commit|Date:"

will show you all options THEMEwith fixing hashes and dates.
