reading ps command's output line by line
hi;

as a pseudo;

while read psLine
do
myFunc $psLine
done < ps

i don't want to redirect ps command's to a file. in fact, my problem is "how can i
read stdout line by line in bash, sed, awk or any?"

thanks,

Hi agn,

The solution u provided is fine.

can't we do like ,

while read psLine
do
myFunc $psLine
done < `ps`

I tested ur solution and this one , the second one is diplaying the value with ^J as the delimiter.

Can somebody tell the difference between the two approches..

Thanks
Penchal
