You can re-symlink /bin/sh to /bin/dash, which can improve system performance, but first you must verify that none of the scripts that aren't. 29 Jul A reoccurring topic on Debian lists is the use of dash (Debian Almquist Shell) as opposed to bash (GNU Bourne-Again Shell). Currently /bin/sh defaults to bash on a Debian system, but some would like the default to be dash.

It can be usefully installed as /bin/sh (because it executes scripts somewhat faster than bash), or as the default super-user shell. Because it depends on fewer libraries, it is therefore less likely to be affected by an upgrade problem or a. GitHub is where people build software.
