In Ubuntu, /bin/sh points to /bin/dash by default.

I want to use /bin/bash as my system-wide shell for /bin/sh. What is the best way to do this?

As shown on this Ubuntu wiki page, you should run

sudo dpkg-reconfigure dash

and select the option not to use /bin/dash as the default shell. Making the change this way will not only fix the symlink /bin/sh, but will also configure other parts of your system to behave correctly, such as making sure that man sh points to the bash manpage instead of the dash one.

    It isn't terribly uncommon for certain software to require this. For example, building Linux From Scratch requires /bin/sh to point to /bin/bash.
