cups does not stop
 

While I was trying to get the Linux driver for our Minolta PagePro working, apparently cups sent a Test Print page to the printer.

For about four days now the printer has been causing some really wierd problems. I could not find any active print jobs on my network, so I thought the printer was starting to fail.

As a last shot, I logged into the Linux system and loaded cups. I then went to Administrative Tasks and found a Test Print job still active? Why didn't this show as an active print job on the network?

It turns out that cups continues to run and trying to send the print job, even though it errors out - waiting for an endjob command, I had quit the cups application and logged out from the system.

I thought that when I quit the cups application that it stopped. So, how do I know what processes like cups are still running in the background?

In MS I have the Task Manager. Is there an equivalent process monitor in Linux?

Thanks

ps is the command you're looking for; it reports on process status. The standard way to invoke it to see all the processes that are running on your system is as "ps -aux", though check the man page for all available switches. grepping the output of this could help once you know what you're looking for, as can the command pgrep, which essentially does the same thing.

Another good command
 

Thanks Dtsazza.

Just one more step in the long learning curve of Linux.
