.SH NAME
cpulimit -- limits the CPU usage of a process
.SH SYNOPSIS
.B cpulimit
\fITARGET \fR[\fIOPTIONS\fR...]
.SH DESCRIPTION
.P
\fITARGET \fRmust be exactly one of these:
.TP
\fB\-p\fR, \fB\-\-pid\fR=\fIN\fR
pid of the process
.TP
\fB\-e\fR, \fB\-\-exe\fR=\fIFILE\fR
name of the executable program file
.TP
\fB\-P\fR, \fB\-\-path\fR=\fIPATH\fR
absolute path name of the executable program file
.P
\fIOPTIONS\fR
.TP
\fB\-l\fR, \fB\-\-limit\fR=\fIN\fR
percentage of CPU allowed from 0 to 100 (mandatory)
.TP
\fB\-v\fR, \fB\-\-verbose\fR

.TP
\fB\-z\fR, \fB\-\-lazy\fR
exit if there is no suitable target process, or if it dies

display this help and exit
.SH EXAMPLES
Assuming you have started \fB`foo \-\-bar`\fR and you find out with \fItop\fR(1) or
\fIps\fR(1) that this process uses all your CPU time you can either
.TP
\[sh] \fBcpulimit \-e foo \-l 50\fR
limits the CPU usage of the process by acting on the executable program file
(note: the argument "\-\-bar" is omitted)
.TP
\[sh] \fBcpulimit \-p 1234 \-l 50\fR
limits the CPU usage of the process by acting on its PID, as shown by
\fIps\fR(1)
.TP
\[sh] \fBcpulimit \-P /usr/bin/foo \-l 50\fR
same as \fI\-e\fR but uses the absolute path name
