command line commands passed to perl script?
Hi all, Sorry, should have added this to my last email. Does anyone know how to pass values to a perl script through the command line? Do you use param as in CGI scripting/ I want a user to be able to specify certain parameters for the perl script (in case they want to run an overnight scheduler on it). Eg. testscript.pl /? gives you help or testscript /a gives you another capability... Ben __________________________________ Do you Yahoo!? New Yahoo!

You should use this: testscript.pl blah where blah is the value to pass. Ben Crane wrote: >Hi all, > >Sorry, should have added this to my last email.

If you want to use the DOS command line switch (/) you could write your own parser for the @ARGV array however Perl provides the Getopt::Std and Getopt::Long modules which use the more standard '-' and '--' for processing command line switches. perldoc Getopt::Std perldoc Getopt::Long John -- use Perl; program fulfillment

=20 IMHO, parsing command-line options sounds a lot easier than it is. Definitely use the modules unless you have a good reason for not doing so. The author(s) of the module have probably already dealt with the forehead-slappers that might not be obvious right off the bat, and it will save you a lot of time down the road. Save your brainpower for the more important parts of your program rather than reinventing this particular wheel. Again, it's just my opinion...

[PATCH] dprofpp
I've been frustrated at times that I can't do this: dprofpp -p 'foo.pl -v 1 -d 4 -flubber -haha' and have it work right. The simple patch (against dprofpp.PL in bleedperl) below my sig makes that work. Given that dprofpp can be used in a lot of ways, I'm not sure what harm it might do... There are a lot of cases in which it WON'T work, but for simple command-line args it does. And that's what I'm after--something which handles more cases than what it does today. Thoughts? Flames?

KDE4 icons and command line commands
I'm running Suse 11.3 with KDE4. I have an icon in my Kickoff Application Launcher for xterm. When I click on the icon, it apparently executes the command /usr/bin/xterm which generates a large window with a large font. I would like to get a smaller window with a smaller font. I know how to do that on a command line but to execute the command I need to _already_ have a window open so I can run the command. So how do I (a) add a new icon to the KDE launcher which generates the command I want or (b) change the existing icon so that it executes MY command and not the basic...
Cool command line prompt command
Last night I rebooted a web server, and after doing so, I couldn't RDP into it. So, in the meanwhile, while I awaited a response from those in power who could go to the data center and physically restart the server, I thought there must be a command line prompt command that I can run from one of the other servers to reboot it. I found a command called shutdown. I ran shutdown /r /f ComputerName and it rebooted the server and then I was able to access it via RDP. shutdown /r /f ComputerName /r - Restart/f - Forced restartRyan OlshanASPInsider | Microsoft MVP, ASP.NEThttp://ryanolshan.c...
