That would be cool. Anyone know of a bash command or tool that will do this?
I use tcsh as my shell. The following alias works nicely for me in
xterm, but would have to be adjusted for anything else:
alias highlight 'sed -E '\''s/\!:*/^[[1m^[[0m/g'\'''
Replace ^[ with an escape character, twice. Put it in your .tcshrc if
you like. YMMV.
Side note, I am tailing sendmail after changes to my outbound queue
runners. I want to highlight my sm-mta-out lines but still see all lines.
Right, I do very similar stuff. You'd use this like:
tail -F /var/log/maillog | highlight .*sm-mta-out.*
Quotes seem to confound this alias. I haven't bothered to fix that; as
long as what you're searching for doesn't glob a file, you should be
fine without quotes.
You can also do more complex things in either sed or awk, colour-coding
individual pattern matches. Here's one in awk that I use to highlight
the activity of milter-greylist:
#!/usr/bin/awk -f
BEGIN {
red=^[[31m; green=^[[32m;
yellow=^[[33m; blue=^[[34m;
norm=^[[0m;
fmt=%s%s%s\n;
}
/autowhitelisted/ { printf(fmt, green, $0, norm); next; }
/delayed for/ { printf(fmt, yellow, $0, norm); next; }
# /skipping greylist/ { printf(fmt, blue, $0, norm); next; }
{ print; }
Same deal with the ^[.
Enjoy.

Grep provides for a number of environmental variables, the above being one of them. For example: export GREP_COLOR='0;32' export GREP_OPTIONS='--color=auto' Perfectly acceptable for regular use, but especially useful to test pattern matching before finalising that script you're working on. -- George ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

While I'm sure there are other ways of achieving this, this is the one I use on a regular basis. --Jon Radel smime.p7s Description: S/MIME Cryptographic Signature

A little late to the party now, but the following Perl script will
'highlight' the lines containing $pattern with a blank line above and
below, surrounded by . The lines not matching will be printed
normally. Note, File::Tail must be installed:
#!/usr/bin/perl
# grep.pl
use warnings;
use strict;
use File::Tail;
my $pattern = submission;
my $log = /var/log/maillog;
my $ref=tie *FH,File::Tail,(name=$log, maxinterval=3);
while (FH) {
if ($_ =~ /$pattern/) {
chop ($_);
print \n $_ \n\n;
} else {
print $_;
}
}

You could use this script: http://www.secnetix.de/olli/scripts/bold It's a filter that works like similar to grep, but it highlights the parts that match your regular expression. The script contains usage information. So you can do things like this: $ tail -f /var/log/maillog | bold -l myhost.mydomain (The -l option specifies to highlight the whole line, not just the part that matches.)
