Yeah.. thats right.. We can do that in awk too..

But my doubt is simple..

In command line the O/P of the below command is
Code:
$ vgdisplay vgesar | grep -i 'Free PE' | awk '{print $NF}'
69

In shell script to assign this O/P to a variable it is
Code:
A=vgesar
FREE=`vgdisplay vgesar | grep -i 'Free PE' | awk '{print $NF}'`
echo $FREE

How to get the above O/P assigned to a variable in perl script ??
