Answer by Epscillon Rules for Remove all files except some from a directory

The answer I was looking for was to run script, but I wanted to avoid deleting the sript itself. So incase someone is looking for a similar answer, do the following.

Create a .sh file and write the following code:

    cp my_run_build.sh ../../     rm -rf * cp      ../../my_run_build.sh .     /*amend rest of the script*/
