Also interesting is "cat /proc/PID/maps" but here one would need to
calculate sizes per line from the two hex addresses given at the start
of each line.
/proc/<pid>/smaps gives a bit more info (including various sizes), but produces
multiple lines per record, making sorting more difficult.
At least on my variant of Linux the following puts the data in one line
and sorts by first size ("Size"). Choosing another columnwould mean
changing the "2" in the sort command.
cat /proc/PID/smaps | \
perl -n -e 'END {print $line, "\n"} chomp(); if ($_ =~ /^[0-9a-f]+-/)
{print $line, "\n"; $line=$_} else {$_ =~ s/.* ([0-9]+ )/$1/; $line =
$line . " | " . $_;}' | \
sort -t '|' -n -k 2
