You can suppress them for specific commands only, for example
Code:

Suppress the expected.
If unexpected things happen then error messages are helpful, otherwise you might get wrong output silently.
Today I am using on that specific line , instead of whole script executing. But

this line making me to think , if for some reason that FS is not mounted during patching then I am missing that important message . Any way I can avoid ? I guess answer would be NO.

NAME
bnproxy - bnetd tracking daemon SYNOPSIS
bntrackd [options] DESCRIPTION
bntrackd is a simple daemon which will listen for UDP announcement packets sent by bnetd(1) servers. The list of servers and their statis- tics is written to a text file an optionally processed by an external program. A perl(1) script is provided which processes this informa- tion to produce an HTML document suitable for display on the web. bnetd(1) servers must be configured to report to tracking servers. The bnetd.conf(5) file allows for multiple tracking servers to be listed separated by commas. The master server is track.bnetd.org. Please consider including that server in your configuration. OPTIONS
-c --command Run the specified command after writing server information to outfile. If this option is not specified, the command "scripts/process.pl" is executed from the directory that bntrackd was started. If an empty string is provided for command, no com- mand will be executed. -e --expire Set the period of time in seconds to keep server information without receiving new updates. If this option is not specified, 600 seconds is used. -d --debug Place additional informational messages in the event log. -h --help --usage Print usage information and exit. -l --logfile Put the event log messages into the specified file. If this option is not specified, the file "logs/bntrackd.log" will be written from the directory that bntrackd was started. If an empty string is provided for logfile, no event messages will be written. -o --outfile Put the server information into the specified file outfile.. -p --port Listen for announcements on the specified UDP port number. If this option is not specified, the port number defaults to 6114. -P --pidfile Record the process ID of the tracking daemon in the specified file. If this option is not specified, this information is not writ- ten to any file. -u --update Set the period of time in seconds between updates of the outfile. If this option is not specified, 150 seconds is used. -v --version Causes bntrackd to print its version number and exit. NOTES
