Question

I’m currently using a compiler that constantly returns warnings, I don’t want to see the warnings. I’ve noticed that all warnings begin with the string “Note :”, so I figured it’s possible to filter out these lines.

I compile with

jrc *.jr

Is there a unix command that alters the output it gives to not print out the lines that begin with “Note :”?

Answer 1

grep -v "^Note:"

Also, you may want to redirect stderr to stdout:

command 2>&1 | grep -v "^Note:"
