What line is necessary at the beginning of a script to tell the OS what to use to run the script?
The special line at the beginning of the script is only necessary if you want the script to be run by a certain command interpreter that is different from your logon shell or because you don't know what environment the user of the shell might be running in. It is a special comment line that looks like: #!/command-name such as: #!/usr/bin/ksh which causes the ksh interpreter to be used for the rest of the shell script.
