I believe the #!/bin/sh shebang translates into something other than bash (mine, for example, a standard Ubuntu Server, defaults to dash).
Since the script seems to work on bash only, why not specify bash there? (Maybe it works with zsh? I don't know, but I believe bash is still pre-installed in all linuxes out there.)
