bash script, I'm using tools like
tcpdump to output results to a file, but wish to hide the standard message displayed on the first output line on the command line after executing the command/script.
conntrack v1.0.0 (conntrack-tools): 6 flow entries have been shown.
After reading the
bash man page, I've tried things like:
conntrack -L|grep "dport=6439" &> /tmp/file
No matter what redirect option I try, the
conntrack message stating the number of flow entries is always displayed in the shell where I execute the script. Same thing goes for
tcpdump where it lists the capturing device and number of packets captured, etc.
Of course, I could add
clear after the
tcpdump commands to quickly hide the output, but that solution is ugly.
How can I hide these kinds of messages?
