thufir@doge:~$ cpulimit -z -b -l 22 -e web content
Error: You must specify exactly one target process
thufir@doge:~$ CPUlimit version 2.1
Usage: cpulimit TARGET [OPTIONS...] [-- PROGRAM]
TARGET must be exactly one of these:
-p, --pid=N pid of the process
-e, --exe=FILE name of the executable program file
The -e option only works when
cpulimit is run with admin rights.
-P, --path=PATH absolute path name of the
executable program file
OPTIONS
-b --background run in background
-c --cpu=N override the detection of CPUs on the machine.
-l, --limit=N percentage of cpu allowed from 1 up.
Usually 1 - 200, but can be higher
on multi-core CPUs (mandatory)
-q, --quiet run in quiet mode (only print errors).
-k, --kill kill processes going over their limit
instead of just throttling them.
-r, --restore Restore processes after they have
been killed. Works with the -k flag.
-s, --signal=SIG Send this signal to the watched process when cpulimit exits.
Signal should be specificed as a number or
SIGTERM, SIGCONT, SIGSTOP, etc. SIGCONT is the default.
-v, --verbose show control statistics
-z, --lazy exit if there is no suitable target process,
or if it dies
-- This is the final CPUlimit option. All following
options are for another program we will launch.
-h, --help display this help and exit
q
The program 'q' can be found in the following packages:
* python-q-text-as-data
* python3-q-text-as-data
Try: sudo apt install <selected package>
