Vmstat
I m checking idle time using vmstat, below are the results
Code:
var=$(ssh wmtmgr@$hostname vmstat | tail -1 | awk '{print $15}')

89

and now im subtracting 89 with 100 & im getting expected results
Code:
expr 100 -  $var

11

Now How can I get the result 11 in one line code?

Code:
 var=$(ssh wmtmgr@$hostname vmstat | tail -1 | awk '{print 100 - $15}')
 echo $var

Thanks,

How about vmstat 1 1 instead of piping through tail -1?

Thanks R.P singh, it works,

@RudiC
If I use vmstat 1 1 or vmstat both are giving same results
