RE: How to Copying/Renaming/Deleting a file in unix?
Copying a File:
To make a duplicate copy of a file, use the command cp.
cp <source> <destination>
So if you want to copy the file hello.txt to the directory Downloads, just type:
cp hello.txt Downloads
To change the name of a file, use the following command format
mv hello.txt hi.txt
Deleting files and directories with the rm command.
