A big thank you to Don for excellent assistance on the script, much appreciated! Smilie

Note that you're setting shell variables mand y, but you are not setting the awk variable my.

Even if your shell doesn't recognize $(...), it would still be much easier to set the month and year in a single invocation of date instead of using date once, two calls to cat, and two calls to cut. Please try changing the first line of my original script to:

Code:

awk -v my=`date +%m%y` '

if your shell doesn't recognize the $(...) form of command substitution. Note that it is important that you use the exact single quote and back quotes as shown.
