Description:

The procps package contains a set of system utilities that 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 are 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.
