Paste it into vim, BBEdit or what ever your choice and run it and it'll return your

my path was to download the ppt perl version of head

and put the personal modification into it
# Get the options.
if ( $ARGV[0] =~ /-(\d+)/ ) {
#
# drieuxish hack to allow for the old school
# head -12 file
$ARGV[0] = -n$1;
}
this way I can still do

Re: [article] Installing 5.8.0 on Jaguar
Apple updated their own copy in an update. Would you use your copy and perhaps some of its libraries? This is the main reason I've decided to keep my entire Perl installation in /usr/local, including all of its modules. Apple's Perl can stay right where it is, Apple can do what it wants to it via its OS upgrades, and I don't worry about it. True. If Apple updated their Perl in the same way as in the past, /usr/bin/perl (which, per the article, is a copy of the same Perl installed in /usr/local/bin/perl) would be wiped out. That new binary would also reenable /System/Library/Perl support. If the Apple install is wipe/replace, then it would also trash your installed modules under /Library/Perl. One other thing I noticed is that you use XML::Parser as an example CPAN module to install. If you are indeed installing Perl on a clean Jaguar install, this will likely fail, as you haven't installed Expat yet. Also, if and when you *do* install Expat, and you install it in /usr/local Perl won't be able to find it, because the /usr/local/lib and /usr/local/include directories didn't exist when you installed Perl. I found this out the hard way myself. Argh. I coulda swore I used HTML::Parser as an example instead of XML::Parser for the exact same reason you mention here. I *know* there's extra magick needed for an XML::Parser install, and I'm surprised I used such a bum example as this. I'll see if I can get it fixed. And finally, in the final section, you discuss CGI. I think it would be important to remind users that, if they're running Apple's Apache, then their CGI scripts will be run under Perl 5.6.0, not 5.8.0. Although you mention earlier that Apache will need to be recompiled, the CGI section should be more explicit about this, IMO. That'd only be the case if the user was running the scripts under mod_perl - normal CGI scripts won't be affected. -- Morbus Iff ( i'm the droid you're looking for ) Culture: http://www.disobey.com/ and http://www.gamegrene.com/ Please Me: http://www.amazon.com/exec/obidos/wishlist/25USVJDH68554 icq: 2927491 / aim: akaMorbus / yahoo: morbus_iff / jabber.org: morbus
