Use the following command to find out how many commits there have been in a git repository. Not really useful in itself, but an interesting figure to see how active a project has been over it's lifetime.

The following git log flags are in use here:

--oneline - Removes some of the information from the log entries and displays each on a single line.

--all - Shows all commits across all branches.

The -l (lower case L) flag is supplied to the wc command so that it counts the number of lines in the given input.
