8.71.1. Installation of Procps-ng

Prepare procps-ng for compilation:

./configure --prefix=/usr                            \
            --docdir=/usr/share/doc/procps-ng-3.3.17 \
            --disable-static                         \
            --disable-kill

The meaning of the configure option:

--disable-kill

This switch disables building the kill command that will be installed by the Util-linux package.

Compile the package:

make

To run the test suite, run:

make check

Five tests related to pkill are known to fail due to a problem with tests that were not updated.

Install the package:

make install

Short Descriptions

free

Reports the amount of free and used memory (both physical and swap memory) in the system

pgrep

Looks up processes based on their name and other attributes

pidof

Reports the PIDs of the given programs

pkill

Signals processes based on their name and other attributes

pmap

Reports the memory map of the given process

ps

Lists the current running processes

pwait

Waits for a process to finish before executing.

pwdx

Reports the current working directory of a process

slabtop

Displays detailed kernel slab cache information in real time

sysctl

Modifies kernel parameters at run time

tload

Prints a graph of the current system load average

top

Displays a list of the most CPU intensive processes; it provides an ongoing look at processor activity in real time

uptime

Reports how long the system has been running, how many users are logged on, and the system load averages

vmstat

Reports virtual memory statistics, giving information about processes, memory, paging, block Input/Output (IO), traps, and CPU activity

w
