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
|

|
.TP
|
||
|
\[sh] \fBcpulimit \-P /usr/bin/foo \-l 50\fR
