Be careful of passing parameters with no checks. For example, a simple way might be:
my $status = system ("fred.bash @ARGV");

then someone calls it like this:
$ myscript.pl 'Program Files'

[download]
and two arguments get passed. You also have a problem if the arguments contain shell meta-characters like quotes, $, or ! in the data, which must be 'escaped' before passing. So you end up having to do something like this before calling system:
for (@ARGV) {$_ = "\Q$_\E"}

My point is that you should not blindly throw data from Perl to the shell. Likewise when using arguments in shell scripts always enclose them in double quotes, including: ".\$1", although even that is not bullet proof.
You might also consider just using one language to solve your problem (Perl or Bash) rather than two. I know, sometimes we do that just to get a job done, but it is not a good long term design.
