Answers

• How do I find processes?

  To find processes running on the system, use the command ps. The manpage describes the different options it takes. Here are some common examples:
  • SunOS 5
    List all of your processes:

    ps -fu yourusername
    

    List all processes on the system:

    ps -aef
    

    SunOS 5 also has /usr/ucb/ps, which acts like the SunOS 4 version of ps.

• What if I want to leave a process running for a long time?

  If you plan to have processes running when you log out, you should leave a note in your .plan file mentioning the processes and the machines they are running on. The operators may kill jobs if you are not logged in and they have reason to believe that they are strays.

  You should probably also ask help which machine(s) are appropriate for running your particular type of job on. We may recommend some machines and/or disallow others.
