He did put it in a 'mild enough' way though.

What shell are you using? Probably bash, right? Well, stop it. Or don’t. Just know why you’re using the shell that you have.

I'm a bash user myself. I've tried zshell but didn't stick with it.

I used bash for years, I was just forced into zsh at work and loved it.

Bash is fine, but I didn't know any of its intricacies. I'm not saying don't use bash. I'm saying don't use bash without learning about how to make it work for you (and probably trying other things).

Meh. I use bash on my laptop and zsh on my VM, and barely notice a difference between the two other than my different prompt. That tells me I'm not getting the most out of it, but it also tells me that the out-of-the-box improvements are pretty minimal. Given how many machines I need to attempt to keep my customizations in sync across (git is barely an option, let alone something like dropbox - this is inside a PCI Level 1 environment), stuff that requires a ton of plugins to really be useful is typically more trouble than its worth. Simply managing my SSH keys is bad enough.

My thoughts exactly. Everything mentioned there is just as doable in bash.

The biggest features I use from zsh is awesome tab completion. For example, partial tab completion:

    $ ls
    ./
    ../
    project-foo/
    project-bar/
    $ cd foo <tab> ----> cd project-foo

Expand paths:

    $ cd /ho/wti/Drop <tab> ----> cd /home/wting/Dropbox

Fuzzy matching:

    $ cd /tpm/blh <tab> ----> cd /tmp/blah

Also expanding remote paths.
