I am writing a script that uses "top" command.
When i use top i can see the average CPU USE:
Cpu(s): 41.9%us, 9.4%sy, 0.0%ni, 48.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
i know i can press "1" to view each CPU separately:
Cpu0 : 8.8%us, 3.0%sy, 0.0%ni, 85.5%id, 2.6%wa, 0.0%hi, 0.1%si, 0.0%st
Cpu1 : 9.7%us, 3.2%sy, 0.0%ni, 83.6%id, 3.4%wa, 0.0%hi, 0.0%si, 0.0%st
but how can i integrate it into a script when i can't use keypresses?
You can press 'W' to save your current state. That will generate a .toprc file in your user's home directory it will also mean that the next time you run top as that user all cores will be shown.
It will look something like:
RCfile for "top with windows" # shameless braggin' Id:a, Mode_altscr=0, Mode_irixps=1, Delay_time=3.000, Curwin=0 Def fieldscur=AEHIOQTWKNMbcdfgjplrsuvyzX winflags=30009, sortindx=10, maxtasks=0 summclr=1, msgsclr=1, headclr=3, taskclr=1 Job fieldscur=ABcefgjlrstuvyzMKNHIWOPQDX winflags=62777, sortindx=0, maxtasks=0 summclr=6, msgsclr=6, headclr=7, taskclr=6 Mem fieldscur=ANOPQRSTUVbcdefgjlmyzWHIKX winflags=62777, sortindx=13, maxtasks=0 summclr=5, msgsclr=5, headclr=4, taskclr=5 Usr fieldscur=ABDECGfhijlopqrstuvyzMKNWX winflags=62777, sortindx=4, maxtasks=0 summclr=3, msgsclr=3, headclr=2, taskclr=3 You can check out man top to understand most of this stuff or just screw around in top and 'W' to see what comes out the other end.
winflags value, 193844 versus 161076 in my case.
