Scripting

• In general
  • Consider executing long running processes during overnight hours when fewer users are on the system
• CPU
  • Use the nice command to keep intensive processes from affecting others
    • The nice -n19 -p$$ placed in a script will make sure it runs at the lowest priority.
    • Run a long command at the lowest CPU priority: nice -n 19 ~/bin/command
    • Change the priority of process 923 (also known as “re-nicing a process”) : renice -17 -p923
• Disk
  • On any commands that will heavily use disk, consider using the ionice command so that scripts will not affect interactive users
    • By adding the ionice -c3 -p$$ command to any script, it will only use disk when idle.
    • You can also run a command or script: ionice -c3 -t ~/bin/command

Disk Quotas

• Soft Limit: 1 GB - You'll get a heads-up if you go over this, but you can still use more space up to the hard limit.
• Hard Limit: 3 GB - This is the max. If you hit this limit, you'll need to clear some space before adding more files.
• Grace Period: 1 week - If you exceed the soft limit, you have 7 days to get back under it before the hard limit kicks in.
