A shell script is just a bunch of commands (both builtin shell
commands and normal Unix utilities, cp(1), ls(1), etc.) stuffed in a
file which is made executable and then run from the command line.
Normally sh(1) is used for shell scripts (although any shell can be
used. If the first line is:
#! /bin/sh
then it's a Bourne (sh(1)) shell script. Take a look at
/etc/periodic/{daily,weekly,monthly} for examples.
If you need to ask such basic questions (please don't take offence,
I'm not being patronizing) then you should get a good book on
the subject. One I would recommend is The Unix Programming Environment
by Brian W. Kernighan (the 'K' in 'K&R') and Rob Pike, Prentice-Hall,
ISBN 0-13-937681-X.
I'm sure there are some good tutorials on the Web but I don't know any
URLs.
Also checkout the sh(1) manpage.
