Some git log examples:

git log
`q` quit to get back to terminal shell prompt;
git log --oneline
# A nice flag for log
git log --pretty=format:"%h%x09%an%x09%ad%x09%s"
# some ASCII art
git log --graph --oneline --decorate --all
# search - need beter examles for this flag
git log -S
git log --all --simplify-by-decoration
# fun with flags:
git log --graph --oneline
