suppress shell script error messages

Question

In my shell script I got these lines:

rm tempfl.txt
rm tempfl2.txt

If these do not exist I get the error messages:

rm: temp         


        

Answer 1

You have two options:

Suppress rm warnings

$ rm tempfl.txt 2> /dev/null

Redirect script output to /dev/null

$ ./myscript.sh 2> /dev/null

The latter has a drawback of missing all other warning messages produced by your script.
