Perl: Command: Line: Parameter: How to print all command line 
parameters?

---

Use the $ARGV array, which contains by design all command line
parameters. It starts with 0, and ends at $#ARGV

===

Steps: Overview:

 1. -Create a Perl file (e.g. 'test.pl') containing text
     similar to the following

--- cut here: begin --------------------------------------------------

my $I = 0;
my $minI = 0;
my $maxI = $#ARGV;
#
for ( $I = $minI; $I <= $maxI; $I++ ) {
 print( "$ARGV[ $I ] \n" );
}

--- cut here: end ----------------------------------------------------

 2. -On the MSDos command line type the command

      perl <your perl filename> <your parameter1> <your parameter2> ...

     e.g.

      perl test.pl myparameter1 myparameter2 myparameter3

      shows the lines

       myparameter1
       myparameter2
       myparameter3
