This is an implementation of SUSv4 ps, and a compatible top, for Linux.

It has the following features:

• Process properties: memory, IO, timing information, etc
• System properties: CPU usage, memory usage, load, etc
• Sort by combinations of properties
• Read defaults from a configuration file
• Flexible process selection (e.g. rss>1M, regexp match on command, etc)
• Flexible output formatting, including CSV output from ps
• Modify top settings on the the fly, without interrupting display
• On-screen help

⚠ I don't use this program any more, do not expect updates. ⚠

./configure
make
sudo make install

See INSTALL for generic instructions.

nps --help
nps --help-format
man nps

nps-top --help
man nps-top

Within nps-top, press h to cycle through help.

nps
nps -ef
nps-top

If you like them more than the system versions:

alias ps=nps
alias top=nps-top
