How do I run a Perl script on multiple input files with the same extension?

Question

How do I run a Perl script on multiple input files with the same extension?

 perl scriptname.pl file.aspx

I'm looking to have it run for all aspx files in the current directory

Thanks!

Answer 1

In your Perl file,

 my @files = <*.aspx>;
 for $file (@files) {

      # do something.

 }

The <*.aspx> is called a glob.

Answer 2

If you are on Linux machine, you could try something like this.

for i in `ls /tmp/*.aspx`; do perl scriptname.pl $i; done

Answer 3

you can pass those files to perl with wildcard

in your script

foreach (@ARGV){
    print "file: $_\n";
    # open your file here...
       #..do something
    # close your file
}

on command line

$ perl myscript.pl *.aspx

Answer 4

You can also pass the path where you have your aspx files and read them one by one.

#!/usr/bin/perl -w

use strict;

my $path = shift;
my @files = split/\n/, `ls *.aspx`;

foreach my $file (@files) {
        do something...
}

Answer 5

You can use glob explicitly, to use shell parameters without depending to much on the shell behaviour.

for my $file ( map {glob($_)} @ARGV ) { 
   print $file, "\n";
};

You may need to control the possibility of a filename duplicate with more than one parameter expanded.
