Hi

File::Spec with the splitpath method can help you determine file paths. This doesn't give the extension, but you can find it yourself pretty easily. Or you can do a quick and dirty split on "/" to get a path and filename. You could do either:

 use File::Spec;
 use warnings;

 foreach my $systempath ( <DATA> )
 {
  chomp $systempath;

  print "-"x50, "\nPATH: $systempath\n\n";
  my ($volume,$directories,$file) = File::Spec->splitpath( $systempath
+ );

  #-- regex with replacement to get the extension
  my $extension = "";
  if ( $file =~ s/(\.[^\.]*)\s*$// )
  {
   $extension = $1;
  }

  print "File::Spec way\n";
  print "Vol\t", $volume, "\n";
  print "Dir\t",$directories, "\n";
  print "File\t", $file, "\n";
  print "Ext\t", $extension, "\n";

}

__DATA__
C:\program files\temp\abc.exe
/usr/local/bin/abc
C:/this/is/a path/only/
/is/this/a/path/or/a/file
/this/is/a/path/

Some further suggestions.

• Don't use $`, $&, etc. See 673. Use the $1, $2, instead
• Use s/// . For example: $extension =~ s/^\.// will remove the leading "." from extension
