1. Get the script here .

2. Move it to a file named ‘copy’.

3. Create a director ‘bin’ in your home directory.

4. Write

export PATH=$PATH:${HOME }/bin/

to your ~/.bashrc file.

5. Execute .bashrc by issuing

[saini@localhost ~]# . .bashrc

6. If you want to copy a file foo.txt to bar.txt then do it as

[saini@localhost ~]# copy foo.txt bar.txt [Enter]

Done.
