    “Do one thing and do it very well” is the UNIX philosophy after all; if you’re 99% likely to just create that missing file after you get a file not found error, why should touch waste your time?

      with this logic, any command that moves, copies or opens a file should just create a new file if it doesn’t exist

      and now you’re just creating new files without realising just because of a typo

      But this directly goes against that philosophy, since now instead of changing timestamps it’s also creating files

        You can pass -c to not create a file, but it does go against the philosophy that it creates them by default instead of that being an option

        EDIT: Looking closer into the code, it would appear to maybe be an efficiency thing based on underlying system calls

        Without that check, touch just opens a file for writing, with no other filesystem check, and closes it

        With that check, touch first checks if the file exists, and then if so opens the file for writing
