If you are in a directory or folder where the script file is available then simply change the file permission in executable mode by doing    chmod  x your filename sh  After that you will run the script by using the following command     sudo   your filename sh  Above the     represent the current directory  Note        If you are not in the directory where the bash script file is present then you change the directory where the file is located by using   cd Directory name write the complete path  command  Otherwise your script can not run
