I'm using Ubuntu 14.04 and I'm experiencing this behavior I can't seem to understand:Run the yes command (in the default shell: Bash)Type CtrlZ to stop yesRun jobs. Output:[1]+  Stopped     yesRun kill -9 %1 to stop yes. Output:[1]+  Stopped     yesRun jobs. Output:[1]+  Stopped     yesThis is on Ubuntu 3.16.0-30-generic running in a parallels virtual machine. Why didn't my kill -9 command terminate the yes command? I thought SIGKILL can't be caught or ignored? And how can I terminate the yes command?
Why doesn't SIGKILL terminate a stopped program (yes)?
shell;job control
