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?
