Questions tagged [pdksh]

pdksh is the public domain clone of the AT&T Bell Labs Korn shell.

pdksh lacks the following features of the official version:

  • The built-in variable LINES.

  • The DEBUG fake signal. The fake signals ERR and EXIT within functions.

  • Functions inherit the trap settings of the main script.

  • The POSIX file expansion character classes ([[:alpha:]], etc.) are not available.

  • The read command and select loop do not use the command-line editing modes.

  • The last command of a pipeline is not run in the parent shell. Thus, echo hi | read x; print $x doesn't work the same as in ksh. (Most Bourne-style shells work this same way.)

  • The set -o option form of ksh is set -X option in pdksh.

pdksh is superseded by mksh, The MirBSD Korn Shell; pdksh has last seen active upstream development in 1999.
