Bobby, I use rexx all the time under linux. Why don't you pipe you grep to a temp file then read that file into a stem var, which you can then parse to your hearts content?

As far as using Perl or Python, I'd rather use Rexx but I'm trying to become a Linux guy instead of am MVS guy and I've got to start somewhere. Yes I know Rexx is available on Linux but for now, I choose bash for good or bad. Guess I'm familiar with arrays (or stacks as they are called in Rexx) so that's what I'll use for now. Aha!, it was my echo command that was wrong.

How can I get everything? This doesn't quite do what you think. How are you referencing the array? $ xyz=(`cat /tmp/test`) $ echo ${xyz[*]} 08:50:01 AM all 3.48 0.00 0.18 0.15 0.19 95.99 09:00:02 AM all 3.51 0.00 0.19 0.15 0.11 96.05 If you just ask for $xyz you get the first element of the array. Another problem is that bash arrays are one-dimensional; you can simulate multidimensional arrays, but why torture yourself? http://tldp.org/LDP/abs/html/arrays.html Perl or Python would be better suited to script processing of text files once the requirements become anything more than simple. If you're really keen on using bash, I'd still suggest using the "read" builtin and shell arithmetic before resorting to arrays. Consider the memory requirements when the input isn't 2 lines, but 2 million.
