/bin/sh should be used for shell scripts, and any scripts should avoid
anything that only Bash supports.

As for perl, /usr/bin/perl is fairly standard if Perl is installed, so I
see no problem leaving it that way.  However, the following could be
used if you want to make perl scripts more flexible:

  #!/usr/bin/env perl

The only real downside to this is if scripts can be run as root.  Using
env method could be a potential vulnerability.
