Re: Mac OS alias from Perl
For the traditional method if you can't find a module or common method just use the quote below the tilde, ie `ln -s /path/to/my/interest / path/to/my/alias`, note if this will run in a cron, you will have to give the full path ot ln, just do a whereis ln command (mine and yours should be in /bin.

Perl handles those natively, and they can be accessed from the command line. The Finder just treats them the same as aliases. Not quite. I forget the details at the moment, but Finder aliases are kind of like firm links: while hardlinks point to inodes, and softlinks point to file pathnames, aliases point to the logical file in a more robust way than symlinks. For example, if the reverent file moves, symlinks break, but aliases shouldn't. If you really want aliases, I think the CPAN modules of Dan Kogai and Chris Nandor are the place to start. I forget who wrote what, but modules like (I think) MacOS::File and Mac::Glue can either make the right calls directly, or leverage Applescript / OSAscript to do this for you. Or if symlinks/softlinks are enough, just use the traditional Perl / Unix methods to make those. -- Chris Devers

Albert, check out CPAN, you should find something like Device::Serialport , I've used a slightly modified version to talk to a keyspan device. dave On 3/7/05 12:13 PM, Albert Kaltenbaeck [EMAIL PROTECTED] wrote: I run a mac server and want to control an external DishNetworks Sat. receiver from my server.

Re: Perl Win32 vs. OS X
Bruce,
depending on the platform of the originating text file, and in OSX that
covers 2 bases really, the newline character is different.
Moc OS9 below = \r
Unix = \n
Dos = \n\r
OSX = \n but many text files are still \r from legacy
So, to make you code good all around, try this instead
if ($line =~ /^\n|\r\n?/) {
# Do Something
}

All,
I am having a problem with a parser which works in DOS, but does not work in

Why would this happen? Any ideas?

Re: Advice for enabling perl on OSX
The one I caught was that you couldn't run it from the command line with proper permissions. Do a whereis perl to ensure it's there, a perl -v to check it's info, and verify that you can run the script from the commandline. dave On Apr 22, 2004, at 6:59 AM, Eric Curts wrote: Greetings! I while back I wrote about assisting a neighboring school district with some perl scripts I had written to allow teachers to easily make web pages. Thanks very much to everyone who gave such good advice. That really helped. Now we are actually in the process of getting the scripts to work for them and have hit an early problem... I loaded a simple script to just test things out (one that just prints out environment variables) and it will not run. When I try to bring up the script I get: Forbidden You don't have permission to access /hck/cgi-bin/printev.cgi on this server. --- - Apache/1.3.26 Server at eagle Port 16080 I set the permissions to 755 for the script, and the folder is web accessible because html files open up fine from that location. When I make a terminal connection and try to run the script from the command line, it will not work either. I think it may be a more fundamental problem, such as needing to edit something in their httpd.conf file or needing to enable something else on the server so that perl scripts will be executed. They have never runs scripts before, so nothing has every been set up for this. I would appreciate any suggestions you have for this problem, especially an idea of what configurations are needed the first time to get an OSX server to execute perl scripts.

Re: Web servers with cable DSL
I actually do this, I run a family web site and a club web site, but I have a couple of special things with my DSL. My provider, Speakeasy.org, explicitely states that it is ok to run your own web services, ie you paid for the bandwith (going both ways!!) so use it as you please. If you greatly abuse it, they may have an issue tho. I also have a particular package which provides reasonable upload capability (600 kB upstream/1.5 mB down w/2 static ip addresses), which makes it so a page doesn't take forever to load. btw, I chose this provider for those very reasons, as I didn't want to do it offline.

Re: Device::SerialPort
Rob, I got it to compile on 10.2, but I had to do some tweaks. I'm using it to talk to serial port on a keyspan usb-serial device, and also in a imac with a stealthport, works great. I used version 0.7 tho, and I'd have to get it down to do a diff. If your interested, I can send you the gzip of a compiled version ready for install, or look at it via a diff, but that'll take longer.

I do have a couple pieces of sample source for talking to serial ports on OSX, but was wondering if anyone else had looked at this type of thing or ported similar code that needs to do ioctl's etc. Specific examples of serial port devices that do show up under OSX in the /dev directory would be the Keyspan USB-serial adaptors and (I believe) the Griffin Stealth Serial plugin card that goes in the modem slot.

Re: DBD::mysql help
Not likely, as if you look at the ones that failed, dropping/adding a
database, those are the ones that need some particular permissions. You can
modify test scripts if you like, but if the access is working, you can
probably install and get to work on it.

What do you want to do with the ending, change it, kill it, or just know it. To kill all of those types, you can use chop to remove the last character, or better yet chomp to only remove \r or \n. Dave gomez
