Is it possible to do a substitute in a value of a variable?

[jtripper6]

I have a directory where a majority of filenames are in the format of basename.ext.new. What I want to do is rename them basename.ext using a perl script. I'm not sure, however, if it's possible to do a substitution on the value of a variable.

#!/usr/bin/perl
  2 @fnames = qx{ls};
  3 $i = 1;
  4 $elements = @fnames;
  5 print "\@fnames has $elements elements.\n";
  6 foreach $element (@fnames) {
  7   if ($element =~ /.new$/) {
  8      print "$i: $element";
  9      $i++;
 10   }
 11 }

If the file ends with .new I want to remove it. I can do it in a shell using the following command:

ls | awk '{print $1}' | perl -pe 's/(.new)//'

I've been unable to incorporate the second part where the substitution occurs. Any ideas?
Thanks,
jt

Are you wanting to rename actual files?

Do you really need to use Perl? With bash, you could just say:
[tt]
for F in *.new; do mv $F $(sed 's/\.new$//' <<< $F); done
[/tt]
