I'm trying to show the number of lines, words and characters of all configuration files in
/etc/*conf (with command
How can I modify the command (or commandline) to not view the error messages?
wc /etc/*conf 2>/dev/null
i don't have access to a shell right now, but you can try something like
cat /etc/*.conf 2> /dev/null | wc -l
That should redirect all the errors and leave the output to be passed to wc
Usually just redirect the standard output to /dev/null to ignore the output, but this is not good practice when writing shell scripts
Try use -q instead to run the shell in quite mode, which will produce less output.
This might not be relevant to the question, but just FYI.
