Unit 7: Git - Logging
Table of Contents
Logging
An important part of Git is keeping track of history and being able to access different points in time. Logging commands help with just that!
git log
git log displays commit history, which includes the author of the commit, the full commit message, timestamp, and commit hash (the seemingly random sequence of letters and numbers that is a unique identifier for each commit).
If the log is long, you may need to use the down arrow key to move down the log. Press Esc to end browsing the log.
For example:
$ git log
