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...

You should use this: testscript.pl  blah
where blah is the value to pass.

ben,
the alternative of course is to look into
        perldoc Getopt::Long
where you can do many majical voodoo with...
Oh dear, just found my old DOG about getopt
<http://www.wetware.com/drieux/pbl/Sys/NextStuff/getOptStd.txt>
oye is that old... and yes it was built to have
code start code that does the GetOpt stuff...

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

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...
