I'm trying to show the number of lines, words and characters of all configuration files in /etc/*conf (with command wc).

How can I modify the command (or commandline) to not view the error messages?

If Roy's answer below doesn't provide what you want, could you provide the command you're trying so we can get an idea of what's not working properly? – Matrix Mole Mar 25 '10 at 22:46

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

this won't allow wc to output word/line/char counts per-file, if that's what the OP wants. it will get the total of all /etc/*conf files. – quack quixote Mar 25 '10 at 23:30
