The MirBSD Korn Shell R33b has just been released; as per the Changelog this is a minor update: portability fixes, support for dæmonising scripts, and manual page improvements.

Online manual: HTML, PDF (ISO A4 paper, we don’t support Imperial units, as even the USA has converted to Metric)

UPDATE 02.04.2008: mksh R33c is out, with a bugfix and a new fully supported OS (ULTRIX 4.5).

mksh R33 has been released; read the ChangeLog for details. (Happy Birthday to everyone who has on this day.)

The news in short and human-readable:

  • Improved build system, once again; better error tracking; better portability with regards to tools in /usr/bin at build and compilers
  • Integrate all changes from OpenBSD ksh
  • Integrate some changes from Debian: the “dot” command needs an argument; prevent namespace conflict between (built-in) aliases and (POSIX, not Korn) shell functions
  • Add \uXXXX and \xXX escapes to the print builtin
  • No longer check if we are called as “sh” for special handling
  • Implement here strings: you can now replace print -r -- "$foo" | command with command <<<"$foo" – like ksh93, zsh; GNU bash behaves differently if and only if $foo is not quoted
  • Implement string replacement ${var/pattern/string}

Especially cool feature: replace x=$(print -r -- "$x" | sed -e 's/foo.*bar/baz/g') with x=${x//foo*bar/baz}

Note: the distfile is not here yet, it’ll take a while to be released. Once it’s uploaded, the mksh homepage will be updated with appropriate information. UPDATE: It’s out now.
