How to get the memory or CPU usage from a pid
sometimes i want to know the memory or cpu usage of just one process.
this can be done easy with ps -p {PID} -o %cpu,%mem
in this examples, i use 28386 as the process id (pid)
if you use the command like this: ps -p {PID} -o %cpu | tail -n1 you get only the number (without the extra line with %MEM or %CPU)
only memory usage:
ps -p 28386 -o %mem
example output:
%MEM
4.0
only cpu usage:
ps -p 28386 -o %cpu
example output:
%CPU
13.2
memory and cpu usage:
ps -p 28386 -o %mem,%cpu
example output:
%CPU %MEM
13.2 4.0
