NAME
       cpulimit -- limits the CPU usage of a process
 
SYNOPSIS
       cpulimit TARGET [OPTIONS...]
 
DESCRIPTION
       TARGET must be exactly one of these:
 
       -p, --pid=N
              pid of the process
 
       -e, --exe=FILE
              name of the executable program file
 
       -P, --path=PATH
              absolute path name of the executable program file
 
       OPTIONS
 
       -l, --limit=N
              percentage of CPU allowed from 0 to 100 (mandatory)
 
       -v, --verbose
              show control statistics
 
       -z, --lazy
              exit if there is no suitable target process, or if it dies
 
       -h, --help
              display this help and exit
 
EXAMPLES
       Assuming  you  have  started "foo --bar" and you find out with top(1) or ps(1) that this process uses all your CPU
       time you can either
 
       # cpulimit -e foo -l 50
              limits the CPU usage of the process by acting on the executable program file (note: the argument "--bar" is
              omitted)
 
       # cpulimit -p 1234 -l 50
              limits the CPU usage of the process by acting on its PID, as shown by ps(1)
 
       # cpulimit -P /usr/bin/foo -l 50
              same as -e but uses the absolute path name
