passing command line arguements to script

[larryperl]

Hi,

I have a my script here--

print "The Perl Script does the User health check and system health check...\n";
print "---------------------------------------------------------------------\n";
# use strict;
my($OS);
$OS = $^O;
# need to test @ARGV before GetOptions shifts it
if (@ARGV == 0) {
   print "\nNo options provided, using defaults (use -h to view options)\n";
}

#GetOptions( 'h|help' => \$_help
        #   ,'u|userdata' => \$_userdata
        #   ,'s|systemdata' => \$_systemdata
		 #  ,'a|authresponsecode' => \$_authresponsecode
		 #  ,'o|outpur_dir' => \$_output_dir);
	  
#if( $_help ) {
  # printUsage(); # automatically exits the program
#}
use Getopt::Std;


##############################################################################
# Print the usage info and automatically exit
##############################################################################
sub printUsage() {
   print "\n\nUsage:";
   print "\n  perl MSLogStat.pl [options] [logfile1] [logfile2] ... [logfile(n)]";
   print "\n\nOptions:";
   print "\n  -h            * display usage help";
   print "\n  -o            * redirect the output to a directory";
   print "\n  -u            * display user related data";
   print "\n  -a            * display auth response codes";
   print "\n  -s            * output only system related data";
   print "\n";
   exit;
}
##############################################################################
# Print the authresponsecode
##############################################################################
sub authResponseCode () {
	print "AAFW_AUTH_SUCCESS				= 0";
	print "AAFW_AUTH_MORESTEPS				= 1";
	print "AAFW_AUTH_ID_NOT_FOUND			= 2";
	print "AAFW_AUTH_INVALID_CREDENTIAL	    = 3";
	print "AAFW_AUTH_ACCOUNT_EXPIRED		= 4";
	print "AAFW_AUTH_ACCOUNT_INACTIVE		= 5";
	print "AAFW_AUTH_ATTEMPTS_EXHAUSTED	    = 6";
	print "AAFW_AUTH_TOKEN_EXPIRED			= 7";
	print "AAFW_AUTH_CHALLENGE_EXPIRED		= 8";
	print "AAFW_AUTH_INVALID_REQUEST		= 9";
	print "AAFW_AUTH_CRED_REISSUED			= 10";
	print "AAFW_AUTH_INTERNAL_ERROR		    = 11";
	print "AAFW_AUTH_UNSUPPORTED_MECH		= 12";
    print "AAFW_AUTH_LAST					= 13";
}
# redirect output to a directory:
if( $_output_dir ) {	
   # does this directory already exist?
   if (! -e $_output_dir) {
      if( $OS =~ "Win32" ) {
      	`mkdir $_output_dir`;
      }
      else
      {
      	`mkdir -p $_output_dir`;      	
      }
   }
   if (! -e $_output_dir) {
      die "Failed to create output directory $_output_dir\n";
   }
}

if( $_authresponsecode ) {
	print "Printing the Auth Response Codes";
	authresponsecode();
}

sub userData() {
   #$LOG = $_logfile_name;
   $username=$2;
   open($LOG,"logfile.txt") or die "\nUnable to open log file:\n";
   @stock = <$LOG>; 
   @matches = (grep(/$username/, @stock));
   print @matches;
}
my $opt = "hu:sao";
my %options;
getopts( $opt , \%options );
printUsage() if  defined  $options{h} ;
authResponseCode() if defined  $options{a} ;
userData() if defined  $options{u} ;

in function userData() i want to make changes so that my script take username as command line arguement and logfile name also to be entered from command line,it can be multiple log files.
Please advice me how can i do that. Please do suggest me if you find something to be changed here to work it more efficiently.

Thanks
NT

You are not using

Getopt::Std

properly. If you want command line switches you can use Getopt and then say:

getopts("a:b:u:hs");

for example. That will automatically put -a data into the variable $opt_a. h and s will be switches and if set (-h for example) will set $opt_h = 1.

So in your username example use:

use Getopt:Std;
getopts("u:"); #the colon makes it an input field vs a switch
$username=$opt_u;
