Why do you think this is SUSE only. Every distro has a default shell, which is what you get when you do not specify the shell to use.
/bin/sh is a link to a shell. Linda, find out which it is in your system.
And note that if you invoke /bin/bash by the /bin/sh link then some bashisms are disabled.
To give an example ...
rudi@tenfore:~> ls -l /bin/sh lrwxrwxrwx 1 root root 4 2012-11-13 23:17 /bin/sh -> bash rudi@tenfore:~> bash -c ". .bashrc" rudi@tenfore:~> sh -c ". .bashrc" sh: line 0: .: .bashrc: file not found rudi@tenfore:~>
Yep! But the most perfide thing is: some of the bashisms still work. If a script still works with "/bin/sh -> bash", do the test again, with "/bin/sh -> ash", as not even zsh, nor (t)csh are disabling all the "extras" when called as /bin/sh . Happy debugging!
