traditionally pushd/popd are csh/tcsh things for walking around
the directory structure - you may have multiple issues that
you will want to think about as you port over this old
csh/tcsh script....
some of the 'modern' forms of /bin/sh also use this, but
of course you do not 'inherit' that "stack" in any of the
sub processes....
So you may want to check why you are pushd/popd-ing all
over the place in the first place - and may wish to think
about re-organizing this so that a simple chain of movement
would suffice:
my @dir_run = qw( first_dir second_dir )
so that you merely pop them off that array - or reference
them by index.....
