Touch a file in Linux
(programming.dev)
Welcome to Programmer Humor!
This is a place where you can post jokes, memes, humor, etc. related to programming!
For sharing awful code theres also Programming Horror.
You might if some other program checks whether that file exists and behaves differently depending on that.
But even still, what's a realistic usecase that would that involve needing a blank, unmodified file in that instance?
One use case is if you're running a web server that is configured to return a "maintenance" page instead of the live site if a particular file exists. Which is actually pretty cool because then you don't have to update the config when you need to do something or let your users get a bunch of 502 errors, you just
touch maintenance
and you're good.That's a good one!
