Full Discussion: Selecting substring (like SQL Server function)

lemme rephrase...

what keywords should I research to find more about the use/features/options of the ":#:#" convention??

e.g. does that feature have a name?!

You know variable expansion covers how the shell interprets variables, but if people don't know the term "expansion", they might query for the wrong things. You get my point...

I've read lots of documentation and have never come across that, I'm thoroughly familiar with sed, my awk knowledge needs to catch up though.

Dude, I really appreciate this technique. It'll be very helpful when extracting certain portions of uniformly-formatted strings and storing to variables.

So if you know of a particular name (keyword) for that string:#:# technique, I'd appreciate it.
