[newbie] shell scripts
OK, I figured out the aliases stuff on my own and made up a more elegant solution, in case any one here wanted to try it. And I'm always up for suggestions: The script /etc/bashrc _IS_ being executed, but just it, not the ~.bashrc as far as I can tell. My problem before was a stupid syntax error. So I have the /etc/bashrc source the ~/.login script, a file I created to hold any and all login to shell type stuff I want. This file in turn sources the .alias file in my directory. So now, new adds go into ~/.alias, and any other at-login style directions can be included in ~/.login. Later, David "Without the Law, there is no Liberty. Without Justice, there is no Law."
Re: [newbie] shell scripts example how to find out dynamically assigned IP address?
Well, I'm trying to find out my dynamically assigned IP address. I got this far: ifconfig ifc grep --context=1 eth1 ifc ifc1 grep "inet addr:" ifc1 ifc2 Now I have to get the IP address from that line I isolated into a variable. Anybody?

Great! Many thanks, For anything shorter, I will need a lot more practice first... Jo Steve Philp wrote: Jo wrote: Well, I'm trying to find out my dynamically assigned IP address.

Well, the question of how depends on the shell you're using. pdksh, csh (c shell), bash all have slightly different err...dialects. Also, you can right "shell" scripts using perl or python. Here's an example in python: Argh...I cannot cut and paste from kedit to netscape messenger...rats...it's the multiple file rename script I wrote a long time ago...it's simple enough to understand.

Copy some of them to your home directory and start hacking away. Look at the O'Rielly Nutshell books, too. MB -- Michael R. Batchelor Industrial Informatics Instrumentation, Inc.

Here's an example from Richard Petersen's handy Linux Programmer's Reference: (Good book to have around) #!/bin/bash #Program to allow the user to select different #ways of listing files echo s.
