Thank you very much?
if youll do man rm -f you can see that it states that the command is used to remove a file or directory. -f is the option with which the command can be used.As per what the $$ are even I am not much aware of it.I tried making a file of the name you suggested and the file name is turned into my_tmp_file_12397.
Can someone help?
