How often do you actually need a blank file though? Usually you'd be writing something in the file.
I'm betting that's why none ever materialized. Most tools that can manipulate a file, can also create that file first, so there's just never been a usecase.
Right-clicking the desktop to create a new txt file in Windows feels so natural, but I can't really think of any time you'd want to create a new file and do nothing with it in a CLI.
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 maintenanceand you're good.That's a good one!
