Why does /bin/sh point to /bin/dash and not /bin/bash? [duplicate]
As far as I understand bash is the default shell in Ubuntu, so why does /bin/sh point to /bin/dash?
Solution 1:
The default login shell is still /bin/bash. What was changed was the default system shell /bin/sh.
The change of the default system shell started from Ubuntu 6.10, and the main reason to switch was efficiency.
