If you're just trying to get a print out of each line of Perl
+ code
         as it executes, the way that "sh -x" provides for shell scrip
+ts,
         you can't use Perl's -D switch. Instead do this

           # If you have "env" utility
           env=PERLDB_OPTS="NonStop=1 AutoTrace=1 frame=2" perl -dS pr
+ogram

           # Bourne shell syntax
           $ PERLDB_OPTS="NonStop=1 AutoTrace=1 frame=2" perl -dS prog
+ram

           # csh syntax
           % (setenv PERLDB_OPTS "NonStop=1 AutoTrace=1 frame=2"; perl
+ -dS program)

         See perldebug for details and variations.
