Hy,

I tryed this
for a in `ps -eo pid,pcpu,comm | sort -n -k2 | grep 'httpd'|tail -10|awk '{print $1}'`; do pwdx $a; done

works but I want to also insert the cpu % in front something like:

for a in `ps -eo pid,pcpu,comm | sort -n -k2 | grep 'httpd'|tail -10|awk '{print $2 " " $1}'`; do pwdx $a; done

but $a takes both values.
how can this be donne?

Thanks,
Cosmin

You need to try as follows:

Code:

#!/bin/bash
ps -eo pid,pcpu,comm | sort -n -k2 | grep 'httpd'|tail -10 | awk '{ print $1 " " $2}' > /tmp/output
while read line; 
do 
 a=$(echo $line | awk '{ print $1 }'); 
 b=$(echo $line | awk '{ print $2 }'); 
 echo "$(pwdx $a) (${b}%)"; 
done < /tmp/output
/bin/rm /tmp/output

Thanks for the solution, this would work in an script but I would prefer to run it as a single line command, I need to run it on several servers.

call pwdx from awk itself:

Code:

 ps -eo pid,pcpu,comm | sort -n -k2 | grep 'httpd'|tail -10|awk '{ORS="% "; system("pwdx " $1); print $2}'

Read awk man page to get more info about ORS variable.

Yep, works great, thank you.
ORS The output record separator, by default a new line.

Thanks,
