Top Forums Shell Programming and Scripting Getting error in command line arguments Post 302181488 by ranj@chn on Thursday 3rd of April 2008 05:15:11 AM

$#

$# tells the no of arguments passed to the script. Since, in your case you have passed 2 arguments, the first "if" condition gets satisfied and the error message gets thrown.

So, if you want to check that the script should take only 2 arguments, use the second if..then in your script.

Code:
if [[ $# -ne 2 ]]
then
..
fi

So, as you keep on adding parameters, change the count here. I hope it is clear now.

Test::Inline::Content::Legacy(3pm)			User Contributed Perl Documentation			Test::Inline::Content::Legacy(3pm)

NAME
Test::Inline::Content::Legacy - Test::Inline 2 Content Handler for legacy functions SYNOPSIS
Custom script content generation using Test::Inline 2.000+ with a custom generator functions my $header = "...."; my $function = sub { my $Object = shift; my $Script = shift; return $header . $Script->merged_content; }; my $Inline = Test::Inline->new( ... file_content => $function, ); Migrating this same code to Test::Inline 2.100+ ContentHandler objects my $header = "...."; my $function = sub { my $Object = shift; my $Script = shift; return $header . $Script->merged_content; }; my $ContentHandler = Test::Inline::Content::Legacy->new( $function ); my $Inline = Test::Inline->new( ... ContentHandler => $ContentHandler, ); DESCRIPTION
This class exists to provide a migration path for anyone using the custom script generators in Test::Inline via the "file_content" param. The synopsis above pretty much says all you need to know. METHODS
new $CODE_ref The "new" constructor for "Test::Inline::Content::Legacy" takes a single parameter of a "CODE" reference, as you would have previously provided directly to "file_content". Returns a new "Test::Inline::Content::Legacy" object, or "undef" if not passed a "CODE" reference. coderef The "coderef" accessor returns the "CODE" reference for the object process $Inline $Script The "process" method works with the legacy function by passing the Test::Inline and Test::Inline::Script arguments straight through to the legacy function, and returning it's result as the return value.
