I have searched for a similar question here, but found nothing related.



In Linux, the dot (.) refers to the directory itself. The touch command creates a file, if it does not exist.



But what does touch . (dot as argument) do?



I have checked the GNU touch documentation and the LINFO information about dot, but found nothing related.



I have tried this command in my Fedora and it seems that nothing is changed.
