filename as argument 1

[woobie]

I'm using Perl on UNIX. How do I make my program take
a filename as an argument? In other words, I have a
program that operates on an existing file and I want to
be able to type in my program name followed by a space followed by a file name and have my program operate on that file. I don't want to have to prompt the user for the filename.

Thanks. [sig][/sig]

Hi,

Look into @ARGV which contains the command-line arguments entered by the user.

if you call your Perl script like this:

perl_script.pl the_data_file

You can get at the filename on the command line like this:

my $fname = shift || die "No filename on command line\n";

As Russ says, the command line arguments are stored in @ARGV, shift returns the first element of @ARGV and then removes it from @ARGV [sig]<p>Mike<br><a href=mailto:michael.j.lacey@ntlworld.com>michael.j.lacey@ntlworld.com</a><br><a href=
