My favourite is setting "git" as a suffix alias to clone repo urls I copy paste:

    alias -s git="git clone"

I always liked tcsh for how they did for loops. It's taken me 20 years of bash and I still always get the syntax wrong the first time. I need to figure out how to alias it.

I like the ^R trick. In bash I usually just !(whatever the string is) which only matches the last one or the more infamous !?(whatever the file/obj you were applying the command to)?

Please, no. Bash (or better, sh) are just fine. They are good enough, and they are standard. I can log in anywhere and do things.

I'd also dare to bet the author's favourite pizza is Hawaiian/pineapple

Salty/sweet contrast is the core of Hawaiian pizza appeal, and flavour/texture contrasts are the foundation of some of the most interesting foods, for instance salted caramel, pork and apples, etc.

Pineapple, banana pepper, and jalapeño may be my favorite pizza.

My favourite feature of zsh (it might be oh-my-zsh), is the tab expansion of unambiguous abbreviated paths. Say if you do:

    $ cd /u/b/l

That will expand into /usr/bin/local. If there are ambiguities at any point, it will expand as much as it can and let you fix it at the point where a decision needs to be made (pressing tab again will show you the options, like Bash et al). For example:

    $ /u/b/gr
    $ /usr/bin/gr
    grep  groff  groups

the kerning in the screenshots is "hilarious"

looks like a version of Comic Sans, possibly http://www.comicneue.com/ or as recently discussed Comic Mono: https://news.ycombinator.com/item?id=25520510 https://dtinth.github.io/comic-mono-font/

Those would be better kerned. This is probably using the default Comic Sans forced to fixed width. Which is predictably bad.

> Ctrl-q "parks" the command

What is the zsh functionality behind this? I couldn't test it because my terminal eats Ctrl-q and a search for "zsh ctrl-q" didn't turn up anything useful.

Knew most of those, not much interested in "shell plugins".

One thing that many people miss are parameter expansions. Those are in Posix, so pretty much any bare shell should be able to use that, too. So dash/bash/zsh/ksh…

    echo Hello ${PLANET:-World}

to have a default if you're not sure a variable is set. Replace "-" with "=" to actually set it, not just use it for this statement.

Or removing suffixes:

    filename=/tmp/foobar.tar.gz
    echo ${filename%.*} # -> /tmp/foobar.tar
    echo ${filename%%.*} # -> /tmp/foobar

Saves you some useless sed/awk.

I still wish the Linux shells (bash/zsh) would start to finally get some more features from friggin' ksh93.

A lot of the tips from TFA can be done in BASH as well and I'm sure the following of my own zsh tips also have a bash equivelant, but I'd like to share anyway:

Pure theme - My absolute favorite shell theme. Has almost all the bells and whistles of the powerlevel9k shown in the article, but looks, much cleaner and less in-your-face.

After downloading the theme, I've added this to my `.zshrc` file:

    # PURE theme - see https://github.com/sindresorhus/pure
    fpath+=$HOME/.zsh/pure
    
    autoload -U promptinit; promptinit
    prompt pure

Fuzzy find makes searching history much more powerful than what is listed in the article. I only use it together with ctr-r, but you can set it up for even more goodness.

    # Fuzzy find - see https://github.com/junegunn/fzf
    [ -f ~/.fzf.zsh ] && source ~/.fzf.zsh

Lastly I've added a syntax highlighter, which is really neat.

      # ZSH Syntax Highlighter - see https://github.com/zsh-users/zsh-syntax-highlighting
      source $HOME/.zsh/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

I don't use oh-my-zsh, but I think my terminal is as fully fledged as even the best oh-my-zsh can offer.

That makes a lot of sense. Admittedly the only Hawaiian pizza I've ever had came from the freezer.

Whenever the local Italian restaurant opens back up I'll go and try a properly made Hawaiian pizza :)
