How do you create a script file in Unix?
A shell script starts with the definition of the interpreter to use. Usually when one says ``shell script'', one means bash script. So a good first line would be #!/bin/bash This says that the program located in the filesystem at /bin/bash should be executed with this script as its input. With a bash script, you can simply start typing a list of commands. Furthermore it is possible to use logic and control structures like if, else, for, while, etc etc. See http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html for a good starting guide.
