U may use some flag, set it as needed and use it to run last command OR not to run.

echo "Listener $LSNR is being ran as $lsnr_ownr owner"...

On HP-UX

Some other shells do support this functionality as well, but you have to type:
set -o emacs

This normally works on BASH shell, so you may have to enable the BASH shell. I know the extended information will come in trailing replies.

$ lsnrctl version|grep Version| awk '{print $5}'| awk -F. '{print $1}'|uniq |head -1
