git log is an excellent command to view the history of commits in your project. There are a number of flags it can take to customize the output. These are some of my favorites.
Returns the entire history of the current branch of your project
git log --oneline
Condensed view of git log. Displays only a truncated commit hash and the commit message.
git log -4
Shows just the last 4 commits
git log -name-status
Shows the files that were changed in each commit
git log -p
Shows the file diff in the log output
git log --after="2019-07-01" --before="2019-09-30"
Shows commits in a date range
git log --grep="mesa verde"
Shows commits where commit message contains a term
git log -- config.py
Shows commits just for a given file
git log -S"heisenberg" # OR git log -G"\bh[a-z]*rg\b"
Shows commits where that term was added to a file. -S flag for text search; -G for regex search
