Extract a column from ps -aux command
Hi,

I have the following output :
Code:
root      9296 81.7  0.2 1115328 20856 ?       Sl   14:38   1:00 /opt/h264rtptranscoder.bin --videoPort=14500 --audioPort=14501 
--serverPort=14500 --framesPerSecond=50 --profilesPath=/opt/transcodingProfiles

I would like to have the following output :


14501 0.2 (third column)


Any suggestions ?

Thanks,

Liviu

do you want to extract audio port also?
# 3  
Old 07-09-2013
Yes, audioPort in numeric format and CPU utilization (which is the 3rd numeric column in the output).

try

Code:
 
your command| awk '{sub(/.*=/,"",$13);print $13" "$4}'

Hi VidyaHar85,

This is what I see by piping my command towards what you've sent me :

/opt/transcodingProfiles 92

This is what I would like to get :

14501 92

Thanks,

Liviu

Code:
export var="root 9296 81.7 0.2 1115328 20856 ? Sl 14:38 1:00 /opt/h264rtptranscoder.bin --videoPort=14500 --audioPort=14501 --serverPort=14500 --framesPerSecond=50 --profilesPath=/opt/transcodingProfiles"

echo $var
root 9296 81.7 0.2 1115328 20856 ? Sl 14:38 1:00 /opt/h264rtptranscoder.bin --videoPort=14500 --audioPort=14501 --serverPort=14500 --framesPerSecond=50 --profilesPath=/opt/transcodingProfiles

echo $var | awk -F'=|--' '/rtptranscoder/{print $5 substr($1, 16, 4)}'
14501 0.2

Code:
ps -eo pcpu,args | awk '{s=$2; sub(".*--audioPort=",""); sub(" .*",""); print $0,s}'

Replace pcpu by pmem, if you mean that.
