Ubuntu Shell file

To run .sh file, you can make it into executable by

chomod u+x file.sh

or

sh file.sh

or

  source file.sh

source command executes the shell file under the current terminal process. It keeps all variables defined in this shell file. 'sh' command ( equal to ./file.sh ) runs the shell file within a newly created subprocess which means that all variables defined in this shell file would be deprecated at the end of the subprocess.
