I don't like the use of perl either. However, please note that perl is "essential": $ dpkg -s perl-base | grep Essential: Essential: yes Thus you can use it and you don't need to add an explicit dependency on it (as long as you don't require any module from the "full" perl package). > The part about the non-maching regexps I > don't get, could you explain that a bit further?

Because ps ax doesn't limit its output when its ouput is piped... at least "ps ax | less" shows you the full line. I wonder if the bug has not been badly diagnosed.
