while true
do
lpstat -a printername
sleep 5
done
this will loop until you do a Control -C

Hi:

# while true; do
> lpstat -a printername
> sleep 5
> done

Using a Ctrl-C will interrupt (terminate) the loop.

Write a little two line script:

lpstat -a printername
echo "full_path_of_myscript" |at now +5 minutes

The invoke that script with "echo "full_path_of_myscript" |at now +5 minutes"

Hi,

the triggy part is
>>
or if I press the enter key
<<

A solution - which is HP specific - is the command
line -t 5
(the -t option is only available under HP-UX):

while :
do
dummy=$(line -t 5)
lpstat -a printer
done
