If you write really portable scripts, i.e. scripts that only use POSIX standard commands and arguments and if these scripts might be executed on heterogeneous platforms, the recommended way, despite popular belief, is either not to use the shebang or to adapt it to the host OS at installation time.

From the Shell Command Language specifications: If the first line of a file of shell commands starts with the characters "#!", the results are unspecified.

#!/bin/sh is not defined by the POSIX standard to point to the location of the POSIX shell. If you run in a POSIX compliant OS and environment and launch an executable script that has no shebang, the proper shell will execute the script, wherever this shell is located.

Thanks for that. Not that my scripts are likely to stray far from linux!
