Worried about a `sudo rm -rf /` kinda thing?

vondur Sep 22, 2021 View on HN

Heck. Have an rm -rf would probably ruin some peoples day on their home directory.

ahoka Dec 30, 2017 View on HN

The problem that it takes a $type="; rm -rf /" to ruin your day.

I bet you've never accidentally rm -rf'ed your home directory or your email archives either.

Defaulting to "rm -rf *" makes me imagine what could possibly go wrong.

gruez Jul 4, 2020 View on HN

agreed. can't wait until I accidentally rm -rf * because I hit an edge case.

purplezooey May 12, 2020 View on HN

Well, that's the last time I'll rm -rf / and not think twice about it.

tyingq Sep 24, 2017 View on HN

Sure, but you could also replace "rm -rf /" with "id" or something else non destructive. Somebody is going to copy paste that snippet and have a bad day.

Sorry, was thinking of the awful `rm -rf /` variant...

the_duke Jan 31, 2017 View on HN

That's kind of like saying the 'rm' command is not well thought out, because many people wouldn't want to delete the whole file system when running 'rm -r /'.
