/bin/sh is a symlink to /bin/bash on ipfire systems. Using /bin/sh in the scripts as shebang hurts in two ways: 1. We use features which do not work with sh as shell. This is not really a problem but if we rely on features of a real bash we can state this clearly. 2. The syntay highlighting in vim does not work without a correct shebang. As I want and need correct syntax highlighting I propose to change the shebang. Signed-off-by: Jonatan Schlag <jonatan.schlag@ipfire.org> Signed-off-by: Michael Tremer <michael.tremer@ipfire.org>
