oksh VS zsh

David Korn's ksh93 was passed on to a new set of developers, who attempted to release a new version; AT&T rolled back these changes due to performance problems which raised questions of support status. It does appear that ksh93 development has resumed, and a new version was released late last year.

The independent pdksh spawned mksh, which is the default shell used in Android (as it has a BSD license); mksh appears to be very much active.

OpenBSD also forked oksh from pdksh. This is certainly well-maintained.

I don't know if this is helpful or just annoying unsolicited "advice"

Anyway, for those of us who like openbsd ksh(all two of us) which is derived from pdksh. there is the project oksh.

I like oksh: https://github.com/ibara/oksh

...and that ksh descended from pdksh, and is distributed as the oksh portable project here:

The MirBSD Korn Shell also descended from pdksh, and it can be found here:

http://www.mirbsd.org/mksh.htm

I don't know about the feature differences and code quality between these two; they both implement most of ksh88, and a small amount of ksh93.

I prefer mksh when I need something more than a POSIX shell.

Brian Callahan publishes a portable version here: https://github.com/ibara/oksh

Porting from OpenBSD, look for the portable versions and their compat layer. https://github.com/ibara/oksh/blob/master/portable.h

https://github.com/zsh-users/zsh/blob/47c7bc9b1493c7374f076b... has a comment about this behaviour, but no justification. I think it's just an optimization to save a little bit of time by not forking, and to avoid having the zsh process hanging around taking resources for no reason.

As a developer, the command line is one of the tools you will be using most frequently. It can be intimidating to venture into the world of CLI tooling but I can assure you it is one of the most rewarding experiences too. In this post I want to walk ya'll through my personal CLI setup. It is based on 3 technologies which I'll coin as the "Holy Trinity" of the command line: TMUX, ZSH, & Neovim.

Just like macOS, bash is included by default in most Linux distributions. Zsh on the other hand, needs to be installed manually. The installation process varies for different distributions but you can always check how to go about it for your distro on zsh website.

POSIX Shell [sh] such as bash[bash] or zsh [zsh] are used to run the commands.

this looks like the zshell implementation.

You can mass rename, using zsh zmv module. Tutorial

I use kitty, with a Nord theme, transparency, and Zsh with Oh My Zsh, using the clean theme.
