mv - move command

mv - user to move a file to another folder or directory.
mv /path/subfolder /path


How to move all files including hidden files into parent directory via *

mv /path/subfolder/* /path/   # your current approach
mv /path/subfolder/.* /path/  # this one for hidden files

Or all together

mv /path/subfolder/{.,}* /path/ 

Which expands to:

mv /path/subfolder/* /path/subfolder/.* /path/

(example: echo a{.,}b expands to a.b ab)
