cpulimit wrapper for limiting CPU of multiple processes
./cpulimit-all.sh --limit=1 -e firefox -e firefox-esr -e chromium -e chrome\ --watch-interval 0 --max-depth=1
Limit CPU of all currently running browser processes to 1%, but do not watch for new processes.
Usage: ./cpulimit-all.sh [TARGET] [OPTIONS...] [-- PROGRAM] TARGET may be one or more of these (either TARGET or PROGRAM is required): -p, --pid=N pid of a process -e, --exe=FILE name of a executable program file -P, --path=PATH absolute path name of a executable program file OPTIONS for ./cpulimit-all.sh --max-depth=N If 0, only target explicitly referenced processes. Otherwise, target subprocesses up to N layers deep. --max-processes=N Maximum number of processes to limit. After this limit is reached, new processes will be limited as old ones die. --watch-interval=INTERVAL If 0, targets will be selected at setup. Otherwise, every INTERVAL (argument to sleep(1)), search for more possible targets. --subprocess-watch-interval=INTERVAL During setup, delay INTERVAL (argument to sleep(1)) between searches for more subprocesses to avoid spending 100% CPU searching for targets. -- This is the final ./cpulimit-all.sh option. All following options are for another program we will launch. -h, --help display this help and exit OPTIONS forwarded to CPUlimit -c, --cpu=N override the detection of CPUs on the machine. -l, --limit=N percentage of cpu allowed from 1 up. Usually 1 - 800, but can be higher on multi-core CPUs (mandatory) -q, --quiet run in quiet mode (only print errors). (Also suppresses messages from ./cpulimit-all.sh.) -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
