Thanks that was just what I needed. Now building on that I tried
this

std_text='No ALTQ support in kernel ALTQ related functions disabled'

ret_ob=`(echo $outrule) | pfctl -a doorman_ob:$session_name_ob -f -
2>&1`
ret_ob=`printf $ret_ob | sed 's/\$std_text//g'`

The goal here is to remove the std_text from the output of the
pftctl command.

I get this error "printf missing format character"

Does sed need different syntax or have I got it all wrong?
