nps

• Process properties: memory, IO, timing information, etc
• System properties: CPU usage, memory usage, load, etc
• Sort by combinations of properties, e.g. TTY first then by memory usage
• Set defaults in a configuration file
• Flexible output formatting:
  • Column widths user-controllable or expand to fit
  • User control over time formats, memory usage abbreviation, etc.

• Compatible with SUSv4 ps
• Flexible process selection:
  • Regexp match on properties, e.g. comm~emacs to get GNU Emacs and XEmacs
  • Compare values, e.g. rss>16M to find heavy memory users (but I repeat myself…)
  • Select by ancestor, user, name, etc.
• --forest to expose process hierarchy
• --csv output for easy spreadsheet import
• --poll to capture information over time

• Configurable system information section
• Modify settings on the fly, without interrupting display
• Pan display left/right to see more than fits in a terminal
• On-screen help
