hello, could anyone recommend a library for, or method of, manipulating lists of strings in textfile format? i need to be able to grep, sort, file etc. up until now i have been using [coll] but its not powerful enough for my needs. recently i have been experimenting with [shell] but it doesn't respond fast enough - if i dump a load of information triggered by an [until] then shell gives me the "old process still running message" i could regulate the flow if info into the [shell] but before i start in that direction i was wondering is there a library or method out there that would do it more efficiently. thanks, rob c
