However, I think you've hit the nail on the head on one aspect. I believe that 6.2 disk was originally set up as dangerously dedicated. It was so long ago and I had forgotten all about it, but this does dovetail with what your are getting at. That may be so for you, but nothing less then FreeBSD8.1 or a Gentoo LiveCD has touched this drive. Gentoo only yo prove to myself that a sucessful ext4 filesystem could be created. GPT/GEOM wasn't used, I used all standard disk-creation methods as described in the gentoo handbook. I also used Gentoo's gpart utilities to independatly verify that any artifacts of GPT/GEOM were removed (which they were). Ok. It may still be useful to see what if anything remains in the areas that GPT uses .. see below. was attempting to do a fresh 'minimal' install of 8.0-Release to the old 6.2 disk pulled off a shelf prior to doing restore(s) of a dump from just the day before. It was only done because it could be done immediately, and a newer, larger, better replacement procured after the fact. This is actually something I fear in reinstalling my other FreeBSD system, which is currently 7.3, which has been upgraded successfully from 6.1. But ports has gotten out of hand and I'm rather tired of trying to fix each port, one at a time when there are prolly hundreds currently installed. For sure. I'm going to wait till 7.4-RELEASE, then reinstall all of the ports on my now 7.4-PRERELEASE system from the set of ports (and esp. packages) resulting from the ports freeze .. that way there's much less chance of inconsistencies and mangled dependencies that often occur when trying to upgrade a lot of ports/packages installed some time ago .. Exact copy of error from my notes here: Unable to find device node for /dev/ad4s1b in /dev! The creation of filesystems will be aborted. Then pressing OK brings this: Couldn't make filesystems properly. Aborting. Yes, this is exactly the same error I get. While that is the same, I think there is an underlying issue here that is causing my issue that doesn't exactly pertain to 'dangerously dedicated'. Sure. This from sysinstall and occurs after fdisk, labeling, at the point when sysinstall then tries to write out the config to the disk and newfs. Yerp, sysinstalls pukes at newfs/swap creation, when it can't find /dev/ad4s1b (which is swap) Or any other form of 'garbage'. I'd use the 8.1 LiveFS CD myself just as a personal preference - but either approach should do the job. Well, the garbage I reported was because of a typo on my part. Yes - I agree. Would also be nice to examine it afterward with a hex editor to actually see *if* all writes were zero. Any 'ones' sprinkled in there, especially in the region of the disk we are talking about would indicate corruption. And my wild guess if this is the situation it may possibly indicate some form of subtle hardware incompatibility most likely a clash of firmwares, e.g. controller and disk(s). Some form of non-standard controller implementation, especially wrt to its firmware being buggy. If someone provides the command for this, I will happily run it and see if the output is all zero's... Ok, let's eg look at the first and last 'tracks' of 63 sectors. If you have somewhere you can copy these to (like a USB stick) then you can do that and examine them on another box with hexdump(1) | less(1). If not, as they're expected to be mostly zeroes, you can do it directly: dd if=/dev/ad4 count=71 | hd | less Not sure if Fixit provides hd /or less, though they appear in /usr/bin? That shows you the boot sector ie MBR, plus anything in sectors 1-62, plus the first 4KB of what will be ad4s1, ie the s1 boot blocks (if they've been ever written there yet and haven't been since cleared) According to your earlier report, your disk has: cylinders=1453521 heads=16 sectors/tracks=63 (1008 blks/cyl) and using that (standard) geometry, reformatted a bit: Offset Size(ST) End Name PTypeDescSubtype Flags 0 6362 -12 unused 0 63 14651491051465149167ad4s18freebsd165 Check: 1453521 * 16 * 63 = 1465149168 sectors, numbered 0..1465149167 So since iseek=0 starts at sector 0, then iseek=1465149167 starts at the last sector, right? So: dd if=/dev/ad4 iseek=1465149104 count=63 | hd shows the last 63 sectors (last track) of the drive. If this isn't all zeroes (which is worth knowing, and recording) then make it so with: dd if=/dev/zero of=/dev/ad4 oseek=1465149104 count=63 which is ok for your blank

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).

And yet, you still have the Useless Use of Cat.
I know I'm joining the party late, but... what about:
grep -Ev '(XYZ|bla)' asdf.txt
or
awk '!/XYZ/ !/bla/ {print}' asdf.txt
ok... end useless contribution.
It's odd that people seem to be taking bla-bla so literally, when it's
clearly a place holder for arbitary text.
Maybe because the OP should have said:
How do I get the text between [XYZ] and [/XYZ]
A demarcing field-search is different than a pruning line-search.
This is what the OP was looking for:
awk -v tag=XYZ '
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 }' asdf.txt
or, if you would prefer to have it all on one line:
awk -v tag=XYZ '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 }' asdf.txt
or, if you would like it as an alias:
for bash...
alias between_xyz='awk -v tag=XYZ '\''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 }'\'
for csh:
alias between_xyz 'awk -v tag=XYZ '\''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 }'\'
Usage:
between_xyz asdf.txt
Of course, this can even be improved upon further...
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.

best way to rebuild all perl ports
hi everyone When i installed FreeBSD 8.1 the other day i was just going to keep it a console-based system with no X just to do a bit of coding and stuff. I then installed perl 5.12. A few days later I changed my mind and installed X with a window manager and a few other things. Somehow - not sure when and why - one of the ports installed perl 5.10 as a dependancy setting itself as the default perl installation for the system so i ended with a mix of ports build against different perl versions. I've mostly fixed this by doing a: `env DISABLE_CONFLICTS=1 portupgrade -o lang/perl5.12 -f perl-5.10.\*` followed by: `portupgrade -fr perl` (which didn't do anything :-/ ) or at least i thought i had, but it seems there are a few perl modules that aren't behaving and i think i need to just rebuild all the perl stuff again. I wondered, should i do this and if so if there's a particular ports-management tool that would be best suited to this? jamie ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Re: best way to rebuild all perl ports
Do you have PERL_VERSION= set correctly in /etc/make.conf? This was set automatically when i first installed perl5.12. This line was later over-written when perl5.10 was installed. Since i used portupgrade to change back to perl5.12 this line has been set correctly. Susbsequent ports i've installed that require perl have been built against 5.12. jamie ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
