In Perl command line argumnet are stored in @ARGV array

$ARGV[0] contains the first argument, $ARGV[1] contains the second argument, etc

Here is simple program for reading a n number of command line Inputs

PHP Code:

  #!/usr/bin/perl

#---------------------#

#  PROGRAM:  commandlineinput.pl  #

#---------------------#

 
foreach $argnum (0 .. $#ARGV) 

{

  print "$ARGV[$argnum]\n";

}

With Perl, command-line arguments are stored in the array named @ARGV.
$ARGV[0] contains the first argument, $ARGV[1] contains the second argument, etc.

$#ARGV is the subscript of the last element of the @ARGV array, so the number of arguments on the command line is $#ARGV + 1.

Hi buddy....

Here's a simple program:

Code:

#!/usr/bin/perl 
$numArgs = $#ARGV + 1; 
print "thanks, you gave me $numArgs command-line arguments.\n"; 
foreach $argnum (0 .. $#ARGV) { 
print "$ARGV[$argnum]\n"; 
}
