| Does anyone here know the difference between the POSIX shell and the Korn Shell? I have been using both recently and so far I cannot tell any difference between them. Anyone? | |

| The Korn shell is an interactive command interpreter and command programming language. It conforms to the Portable Operating System Interface for Computer Environments (POSIX), an international standard for operating systems. POSIX is not an operating system, but is a standard aimed at portability of applications, at the source level, across many systems. POSIX features are built on top of the Korn shell. The Korn shell (also known as the POSIX shell) offers many of the same features as the Bourne and C shells, such as I/O redirection capabilities, variable substitution, and file name substitution. It also includes several additional command and programming language features:

| I know that POSIX is the name of a standard, but in Rafeeq Rehman's book about the HP-UX operating system, he says that the default shell for HP-UX is the POSIX shell, located at /usr/bin/sh (this is NOT the Bourne shell, which is located at /usr/old/bin/sh). The POSIX shell is not a link to any other file, but to me it seems to work just like the Korn shell, so I was wondering if anyone knew what the differences were. Thanks anyway. |
