Git Protip: Learning from your history (git log)

I've been sending weekly "Protip" emails about Git to the rest of engineering here at Slide for a while now, using the "Protips" as a means of introducing more interesting and complex features Git offers. Below is the second Protip written to date.





One of the major benefits to using Git is the entirety of the repository being entirely local and easily searched/queried. For this, Git has a very useful command called git log which allows you to inspect revision histories in numerous different ways between file paths, branches, etc. There are a couple basic scenarios where git log has become invaluable, for me at least, in order to properly review code but also to track changes effectively from point A to point B.


All git log commands automatically filter into less(1) so you can page through the output like you would normally if you executed a svn log | less. Because git log is simply reading from the locally stored revision history you can quickly grep the history by any number of different search criteria to gain a better understanding of how the code base is changing and where.

For more specific usage of `git log` refer to the git log man page
