There’s a linux command, called “touch” which sets the timestamp on a file. It’s used for several things, including testing that the user has write privileges and that the filesystem is working.

I heard of a sysadmin who used to use “touch kids”, creating or updating the file ‘kids’. Some sort of internalised joke, I assume. His boss told him not to because it was inappropriate. Then again formally when he kept on doing it. Dude couldn’t stop, like some form of muscle memory. Kept on using kids as a test filename.

So yeah, he got sacked pretty quickly.
