| 29 | <application>Dash</application> is a POSIX compliant shell. It can be

| 30 | installed as /bin/sh or as the default shell for either <systemitem
|
---|
| 31 | class="username">root</systemitem> or a second user with a userid of 0.
|
---|
| 32 | It depends on fewer libraries than the <application>Bash</application>
|
---|
| 33 | shell and is therefore less likely to be affected by an upgrade problem
|
---|
| 34 | or disk failure. <application>Dash</application> is also useful for
|
---|
| 35 | checking that a script is completely compatible with POSIX syntax.
