wicd-cli Script

Hi all,
first time poster here. After making the switch from Ubuntu, I was faced with the uneasy task of configuring wireless networking for my stripped back Arch/ratpoison laptop via the command line (one of the prices to pay for a 30 MB of RAM build!), so I wrote this script to ease the pain of using wicd. I thought I'd share it here since this is my first bash script, I'm after ideas for expanding it's versatility in areas such as encrypted networks, more options etc etc (the sky/my stupidity is the limit). It's very primitive but it scans for wireless networks and then attempts to connect to one chosen by the user and then performs a ping to check it's connectivity.

All comments appreciated, thanks!

Best regards,
Chris

Re: wicd-cli Script

I've noticed that this site's 'code' feature has messed around with my tabbed comments a bit, how does it handle them? It's written with tab space set to 4.
