Note that in Ubuntu and Debian, /bin/sh is dash, not bash, which is
more strict in its posix sh(1) conformance ('==' for string comparisons
is a bashism). Login shells by default use bash, but shell scripts,
unless explicitly using bash via "#!/bin/bash" will by default be
interpreted by dash.

The checkbashisms script from the devscripts package on Debian and
Ubuntu will highlight issues for you.
