[asterisk-users] say I wish to run tail command on messages file to pick up if any "channels unavailable" messages appear.

[Danny Nicholas]

Try this first:
Cat /var/log/asterisk/messages|grep "channels unavailable"

Once you get grep output from this, changing the grep on the tail command
should produce the desired results.

Since the tail -f is a dynamic situation, it is much easier to make the test
on the fixed cat command.
