This could mean almost anything (witness another response which excludes lines containing blah or XYZ, which gives the desired output on your test input). Are you actually trying to extract all the lines inside [XYZ]...[/XYZ] tags? are the tags guaranteed not to occur on the lines you need to extract, as they appear here? Because (all on one line) perl -ne 'print if ($check = m{\[XYZ\]} .. m{\[/XYZ\]}) 1 and $check !~ /E0$/' asdf.txt output.txt produces the same output as you have above for the test input. (The .. range operator in scalar context is true as soon as the left-hand expression is true, and false as soon as the right-hand expression is true. It returns 1 each time it becomes true, incrementing integers as it stays true, and appends E0 to the last number as it becomes false, which lets you exclude both endpoints).

As a shell function: # between $what $file [$file ...] # # Split out lines between [$what] and [/$what] using awk(1). # between() { awk -v tag=$1 ' BEGIN { buf = } $0 ~ \\[tag\\], $0 ~ \\[/tag\\] \ { if ( match($0, \\[/tag\\]) ) \ { buf = buf substr($0, 0, RSTART - 1) sub(.*\\[tag\\], , buf) sub(/^\n*/, , buf) sub(/\n*$/, , buf) print buf buf = next } else buf = buf $0\n } END { if ( length(buf) ) print buf } ' $@ } Or, for those csh users, how about a fancy alias?: alias between 'awk -v tag=\!^ '\''BEGIN { buf = } $0 ~ \\[tag\ \], $0 ~ \\[/tag\\] { if ( match($0, \\[/tag\\]) ) { buf = buf substr($0, 0, RSTART - 1); sub(.*\\[tag\\], , buf); sub(/^\n*/, , buf); sub(/\n*$/, , buf); print buf; buf = ; next } else buf = buf $0\n } END { if ( length(buf) ) print buf }'\'' \!:2-$' Usage: between XYZ asdf.txt AND... (lol)... last but not least... If you want to have case-insensitivity, you'll have to change: BEGIN { buf = } to: BEGIN { IGNORECASE = 1; buf = } NOTE: FYI, when you need to grab text that spans multiple lines between two field delimiters, C/C++ is superior to perl/awk which excel at line- based I/O versus block I/O. However, I conclude that the OP wanted something that was executable from the command-line (considering that he/she actually gave a basic construct for a perl one-liner (which might as well be an awk one-liner considering FreeBSD doesn't come with Perl in the base anymore and thus not every machine is guaranteed to have perl -- while every machine has awk). ANOTHER NOTE: The above is not intended to start a language flame-war... just an observation. If you have observed an easy _and_ convenient method that _does_ use perl/awk (in a manner more efficient than the above), I'm sure the OP/list would love it. Otherwise, I really do view this operation as being easier in C using functions like strchr, strrchr, etc. -- Cheers, Devin Teske - CONTACT INFORMATION - Business Solutions Consultant II FIS - fisglobal.com 510-735-5650 Mobile 510-621-2038 Office 510-621-2020 Office Fax 909-477-4578 Home/Fax devin.te...@fisglobal.com - LEGAL DISCLAIMER - This message

I guess I was a little thrown because the bsdpan modules are showing up with portversion and portupgrade, which I had always associated with just the ports database and ports collection. And yes, if you can find expected module in ports tree, it is better install from ports than install from cpan driectly.. Okay...question... When I set up this server, it was (at the time) just for the purpose of this portal server (web based). I followed their directions for Linux and FreeBSD, and did it to the letter, etc...a lot of install this and this from CPAN using this command line instruction... etc. etc. In this case, R'ing the F'ing M was apparently a bad idea :-( Wish this server software were available as a port! Anyway, I am tentatively hoping to replace the bsdpan modules with ports' p5 modules. Is there a method AND ORDER to best attempt this, so the application (hopefully) won't break? I don't want to install a p5 port and remove a bsdpan module only to have the bsdpan module erase parts of the p5 modules in the process :-( -Bart ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

It works without problems(ideally ofcourse). Always use ports if you can and there should be no problems installing software like you might find on linux. To see the differences go to /usr/ports/lang/per_or_whatever and you can read everything in there. The files folder contains the actual patches and changes to the original source to make it work without problems. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

OT: Another perl question
Is there an easy way of determining file - determine file type in perl? at least as certain as magic(5) can ascertain? E.g: if (($ftype = file ($ARV[i])) eq script){ ## do abc; } else if ($ftype eq Mail){ ## do def; } else if ($type eq C program){ ## do xyz; } . . .

RE: Perl question... calculating difference in time..
look into the perl module Date::Calc, it's has ALOT of features that are quite useful for date manipulation. jeff. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Eric Six Sent: Thursday, December 05, 2002 1:44 PM To: '[EMAIL PROTECTED]' Subject: Perl question... calculating difference in time.. I know this isn't a perl list, but this is a perl on freebsd question! ;) I have a script that is sorting log files. I want to calculate the total time between log entrys. Here is the format of the log files: Dec 05 09:51:48.452 info info.info data ... Dec 05 09:53:49.543 info info.info data The output should return something along the lines of: total time between log entries 02:01:01.091. I have the time fields pulled out but I cannot figure out how to seprate them into a calculatable format. And if this was run from after midnight and the log files rolled back to 23:00, how to calculate this..Any help is much appreciated!

The Time::ParseDate module by David Muir Sharnoff looks just the ticket. http://search.cpan.org/author/MUIR/Time-modules-2002.1001/lib/Time/ParseDate.pm It essentially does the reverse of strftime(3) --- and once you've got the time expressed as seconds since the epoch, the rest of the calculations required should be easy. It's available in ports as part of devel/p5-Time.
