in reply to Usage of a sparse file

I've found this works

my $total=`du --block-size=1 $line`; my $junk; chomp($total); ($total,$junk)=split /\t/, $total, 2;
But I'd like to do it in perl rather than calling out to the shell.

    Just a parenthetic note. If  $junk is something you don't care about at all, then you don't need to bother capturing it:

    >perl -wMstrict -le "my $total = qq{123\tasdfghhj\n}; print qq{[$total]]}; ;; ($total) = split /\t/, $total, 2; print qq{'$total'}; " [123 asdfghhj ]] '123'
