Bash script for wireless

[John O'Hagan <johnohagan@iprimus.com.au>]

Hi,

Calling all scripting experts! I'm trying to write a script which will present 
a list of available wireless networks as a menu, from which the user can 
select one to connect to.

I want to take selected parts of the output of `iwlist scan` as variables, but 
have been unable to find out how to do this in online scripting guides. I 
know how to use grep etc. to find known bits of output, but not how to 
isolate arbitrary output, for example ESSID names.

Can anyone point me in the right direction?

Thanks,

John
