From the Debian Policy Manual:

All command scripts, including the package maintainer scripts inside
the package and used by dpkg, should have a #! line naming the shell
to be used to interpret them. In the case of Perl scripts this
should be #!/usr/bin/perl.

....

Shell scripts (sh and bash) other than init.d scripts should almost
certainly start with set -e so that errors are detected. init.d
scripts are something of a special case, due to how frequently they
need to call commands that are allowed to fail, and it may instead be
easier to check the exit status of commands directly. See Writing the
scripts, Section 9.3.2 for more information about writing init.d
scripts.

...

If a shell script requires non-SUSv3 features from the shell
interpreter other than those listed above, the appropriate shell must
be specified in the first line of the script (e.g., #!/bin/bash) and
the package must depend on the package providing the shell (unless
the shell package is marked "Essential", as in the case of bash).

...

If in doubt whether a script complies with these requirements, use
/bin/bash.

...

csh and tcsh should be avoided as scripting languages.
