Okay. Odd, but possible.

To my knowledge, cd is not a Perl command. Are referring to a shell
command from the command prompt?? You should not assume that you can
make any conclusions out from that as regards the need to escape
things in Perl.

Do you always write strings in Perl code without quotes? Suppose not.
Please show us what you actually wrote, or else it's hard to help you.

Btw, have you studied the posting guidelines for this group?

In your previous message you said that you did:

     $fileName =~ s/\$/\\\$/g;

         if (-e $fileName) {

etc., but if $fileName had been assigned the string
'/var/newbinary/$BASEDIR/bin/foo', you should _not_ add that
backslash.
