The script itself is not doing that.

He did:

I don't see anything in your script that is changing directory, but I
_highly_ suspect that you have something else, such as $ENV, or an old
version of bash that is vulnerable to 'x=() { :;}; cd' accidentally
executing 'cd' as the first thing during bash startup.

Try running 'bash -vx lf' to see if that gives you more hints about code
being run prior to the start of your script.
