Description:

The procps package contains a set of system utilities which provide
system information. Procps includes ps, free, skill, snice,
tload, top, uptime, vmstat, w, and watch. The ps command displays
a snapshot of running processes. The top command provides a
repetitive update of the statuses of running processes. The free
command displays the amounts of free and used memory on your system.
The skill command sends a terminate command (or another specified signal)
to a specified set of processes. The snice command is used to change the
scheduling priority of specified processes. The tload command prints a graph
of the current system load average to a specified tty. The uptime command
displays the current time, how long the system has been running, how many
users are logged on and system load averages for the past one, five and
fifteen minutes. The w command displays a list of the users who
are currently logged on and what they're running. The watch program
watches a running program. The vmstat command displays virtual
memory statistics about processes, memory, paging, block I/O, traps
and CPU activity.
