This is to announce a new version of the public domain ksh, a clone
of the AT&T Korn shell. This version is believed to be quite stable.
It is available from:
ftp.cs.mun.ca:pub/pdksh/pdksh-5.1.0.tar.gz (320 kbytes)
[MD5 (pdksh-5.1.0.tar.gz) = 167eeb19992945fdec44ae81a097fd89]
(newer versions will also be placed here as they are created)
The following bits are extracted from the README file:
PD-ksh is a mostly complete AT&T ksh look-alike (see NOTES file for a list
of things not supported). Work is currently underway to make it fully
compatible with both POSIX and AT&T ksh (when the two don't conflict).
Since pdksh is free and compiles and runs on most common unix systems, it
is very useful in creating a consistent user interface across multiple
machines. For example, in the CS dept. of MUN, pdksh is installed on a
variety of machines including Suns, HPs, DecStations, pcs running Linux,
etc., and is the login shell of ~3700 users.
suggestion. A short list of things that have been added since the last
public pdksh release (4.9) are auto-configuration, arrays, $(( .. )),
[[ .. ]], variable attributes, co-processes, many POSIXisms and many bug
fixes. See the NEWS and ChangeLog files for other features added and bugs
Note that pdksh is provided AS IS, with NO WARRANTY, either expressed or
implied. Also note that although the bulk of the code in pdksh is in the
public domain, some files are copyrighten (but freely distributable) and
subject to certain conditions (eg, don't remove copyright, document any
The following lists things in AT&T ksh that aren't in pdksh yet (taken
from the NOTES file):
General features of at&t ksh that are not (yet) in pdksh:
- exported aliases.
- exported functions.
- set -t.
- signals/traps not cleared during functions.
- trap DEBUG, local ERR and EXIT traps in functions.
- ERRNO, LINENO, LINES parameters.
- cd/pwd doesn't have -L or -P options (not all at&t ksh's have this).
Also, doesn't have posix file globbing (eg, [[:alpha:]], etc.)
- use of an `agent' to execute unreadable/setuid/setgid shell scripts
