Here...

Code:
cat file | cut -d "," -f 1,2 | grep 11

The command cat streams file to the standard output and we pipe it to cut command that extracts specific field from the file. "-d" sets the delimiter, in our case it is comma, "-f" species fields (columns) you want to extract (you can change/add your own list of cause) and eventually "grep" selects only these records that feature number 11 (it may be anything again).
Get "UNIX Essentials and UNIX Core" DVD it teaches things like that.

Hope it helps.
