How to tell if a file is git tracked (by shell exit code)?

Question

Is there a way to tell if a file is being tracked by running some git command and checking its exit code?

In other words: is git tracking a file?

Answer 1

Just my two cents:

git ls-files | grep -x relative/path

where relative/path can be easily determined by pressing tab within an auto-completion shell. Add an additional | wc -l to get a 1 or 0 output.
