Here is an interesting article which explains how to write scripts in a very simple way. A must read http://www.knowurtech.com/linux/writing_scripts.html In general also i found this site quite interesting. Cheers!! Dinesh

Lots of errors there too.

Okay, I'm a bit new to shell scripting but learning. What's wrong with writing a shell script as root so long as the script does not have root privileges itself? There was very little about this in the 3 or 4 books I have been using to learn shell scripting, so I'm wondering if I (or they) missed something. No, I won't go to Dinesh's site that shall remain nameless to find out! Thanks ... Rich

If you write and test them as root, the simplest coding error could wipe your whole system. Write scripts as a regular user and never test scripts with live data. Only after you are sure it is working do you run it with live data or as root. |
