hi, following is the regex (in perl) that i have came up w/ so far to filter large make logs, like (build|install)(world|kernel). does anybody have suggestions for other "interesting" regexes? ------- filter-log .perl -------- #!/usr/bin/perl -w use strict; # line-wise buffering $|=1; while (<>) { # print "status" & errors+warnings, but not compiler lines print if (m#[-=>]{3,}|\b(?:warning:|error|stop)#i && ! m#^cc.+#i); # print 'time' statistics print if m#(?:real|user|sys)\s+\d+m\d+\.\d{3}s# } ---------------------------- i use it like this... # cd /source/src && (make buildworld )>& /log/some/where & # # tail -f /log/some/where | filter-log ideally i would have done this, tail included... ------- filter-log .sh -------- #!/bin/sh if (test -f $1 -a -r $1) then tail -f | egrep -i '\-\-\-|===|warning:|error|stop|real.*m.s' | grep -v '^cc ' fi ---------------------------- ...but due to buffering, 2d grep would result in no output; otherwise i would have to sacrifice the 2d grep... any suggestions? -- so, do you like word games or scrabble? - parv To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
