calculating total and free disk space on a system

[Viktor Balogh · Accepted solution]

here it is corrected:

vgdisplay 2>/dev/null |grep "VG Name"|awk '{print $3}'|while read a
do
vgdisplay $a|grep "PE Size"|awk '{print $4}'|read b
vgdisplay $a|grep "Total PE"|awk '{print $3}'|read c
vgdisplay $a|grep "Free PE"|awk '{print $3}'|read d
echo "$a $((b*c)) $((b*d))"
done



it should work like a charm:

# vgdisplay 2>/dev/null |grep "VG Name"|awk '{print $3}'|while read a
> do
> vgdisplay $a|grep "PE Size"|awk '{print $4}'|read b
> vgdisplay $a|grep "Total PE"|awk '{print $3}'|read c
> vgdisplay $a|grep "Free PE"|awk '{print $3}'|read d
> echo "$a $((b*c)) $((b*d))"
> done
/dev/vg00 139968 63712
/dev/vghomeora 139968 103968
/dev/vgquorum1 14368 13856
/dev/vgignite 115072 30336

there was a pipe in the first line at the end of the awk statement ;)
(and i added the error redirection just to don't get confused because of disabled VGs)
