/bin/sh - POSIX?

[Yongwei Wu]

>From the man page:

Bash is largely compatible with `sh' and incorporates useful
features from the Korn shell `ksh' and the C shell `csh'.  It is
intended to be a conformant implementation of the IEEE POSIX Shell and
Tools portion of the IEEE POSIX specification (IEEE Standard 1003.1).
It offers functional improvements over `sh' for both interactive and
programming use.

and

Starting Bash with the `--posix' command-line option or executing `set
-o posix' while Bash is running will cause Bash to conform more closely
to the POSIX standard by changing the behavior to match that specified
by POSIX in areas where the Bash default differs.

When invoked as `sh', Bash enters POSIX mode after reading the
startup files.
