Hello,
I would like to pipe two variables into awk, but I don't know how to do.
Each variable, "a" and "b", are in fact a list of data. They are not files.

I was running a script using bash where there is some write to pipe error at some point causing the tee command to exit abruptly while the script continues to run. The newer version of tee seems to prevent... (2 Replies)
