I have input from a "df -k /home" that looks like this:

filesystem kbytes used avail capacity mounted on /dev/dsk/c0b0t0d0s4 12209400 5496486 6712914 46% /home

And a function that parses it for the capacity (creatively named no less):

sub parse_capacity { my ($df_output) = @_; my $capacity; if ($df_output =~ m[(\d+)%\s+/home$]) { $capacity = $1; } else { $capacity = 'Match Error'; } return $capacity; }

This works. I should be done right? Noooo, I'm looking for a more idiomatic way to rewrite the "if regex" for purely aesthetic reasons.

I tried:

($df_output =~ m[(\d+)%\s+/home$]) ? $capacity = $1 : $capacity = 'Mat +ch Error';

Which returns 'Match Error' every time.

Why does the ternary statement not work?
What are the some of the more Perlish ways to rephrase that if statment?

Thanks,
