- Version 2.0 Release Notes:
-
- Release 2.0 has had significant parts re-written and much of the POSIX (Korn)
- Shell functionality implemented.
-
- Addition New Functionality:
-
- 1. The format of the history file has changed match some of the
- functionality provided by the POSIX shell.
-
- 2. The format of the EXTENDED_LINE file has changed to provide a number of
- difference ways of processing command line parameters and overcoming
- the 127 or 255 byte limitation of DOS and OS/2.
-
- 3. The OS/2 port has been tested (on release 1.3 and 2.0 beta) and a number
- of OS/2 specific builtins have been added.
-
- Missing POSIX Shell functionality:
-
- 1. The PS1 prompt is not expanded.
- 2. The getopts builtin is not implemented
- 3. POSIX command line editing is not implemented.
- 4. OS/2 uses files and not pipes to pipe data.
-
- The following enhancements/bugs remain outstanding:
-
- 1. The processing of the escape character (\) is not consistent with the
- Korn shell. The MS-Shell always strips the first escape character.
- The Korn shell only strips escape characters when it detects a shell
- special character following.
-
- ie. echo "\033[H" works under Korn however echo "\\033[H" is required
- in the MSDOS shell.
-
- This problem requires a large amount of rework to one 30K source file
- and I haven't been able to start on it yet.
-
- 2. 8 Bit character are not supported. This is tied in with the processing
- of escape characters. The shell uses the 8-bit to mark escaped
- characters.
-
- 3. Interrupting a swap at the wrong time may cause the shell to hang. I've
- not been able to track this down.
