Full Discussion: Suppressing errors from command output
Operating Systems HP-UX Suppressing errors from command output Post 303017377 by anaigini45 on Tuesday 15th of May 2018 04:11:10 AM

I tried these methods to redirect stderr to /dev/null, and still that message pops :

Code:
$ sudo print_manifest | grep "Main Memory" > /dev/null 2>&1
NOTE: Could not read the /etc/resolv.conf file.
$ sudo print_manifest | grep "Main Memory" &>/dev/null
[1]     7684
$ NOTE: Could not read the /etc/resolv.conf file.
    Main Memory:        196498 MB

Are the commands I am using above correct?
If so, then seems like redirecting the error wont work. Need to touch the file?
