I am not someone who complains about "stop piping cats" but using '-e' with grep is a lot quicker and easier to read. This: grep -v 'test/' | grep -v 'test

I am not someone who complains about "stop piping cats" but using '-e' with grep is a lot quicker and easier to read. This: grep -v 'test/' | grep -v 'tests/' | grep -v idlelib | grep -v turtledemo Becomes: grep -ve 'test/' -e 'tests/' -e idlelib -e turtledemo

To be fair, the advantage of doing separate greps is working iteratively and drilling down on what you want.

  You can iteratively add the -e flags just the same.

    Sure, for the basic example of 5 simple greps. Usually I have some additional flags or steps in between too.

not this? grep -ve 'test/|tests/|idlelib|turtledemo'

  That would be -vE, or you have to escape the pipe symbols.

    Couldn't it also be -vP?

Thanks, that's a useful tip.

  Also since ripgrep is already installed "grep -v" can be replaced with "rg -v"
