How can I exclude directories from grep -R?
...bugger and I am not interested in those results. Also I just wish to omit .idea and .git hidden directories because I don't care about those search locations either, and wish to keep the search performant.
So here is the result - I create a script called findDebugger.sh with:
#!/usr/bin/env bash
