I have an O/p file below and I'm looking for a bash and Perl solution:
Aggregate total used avail capacity
aggr0 100 59 41 41%
aggr1 200 100 100 50%
aggr2 300 150 150 50%
aggr3 400 200 200 50%
I would like to calculate the sum of all individual column except Col-1. The final state should look like this:
Aggregate total used avail capacity
aggr0 100 59 41 41%
aggr1 200 100 100 50%
aggr2 300 150 150 50%
aggr3 400 200 200 50%
=========================================================
1000 509 460 50.9% (Used % of all aggr's)
infile是其中包含数据的文件
perl -ape 'next if $.==1; for my $i (1..4) { $s[$i] += $F[$i]; } END { $s[4]=sprintf("%.2f%%",$s[2]/$s[1]*100); $"="\t";print "total\t\t @s\n";}'
Perl is probably more suitable to this task, but it can be done from bash too :)
tail -n +2 my_op_file.txt | while read n c1 c2 c3 c4;do
total=$(($total + $c1 ))
used=$(($used + $c2 ))
avail=$(($avail + $c3 ))
capacity=$(($capacity + ${c4%%%}))
echo $total $used $avail $capacity
done
