How to navigate directories faster with Bash (2015)

Re:How to navigate directories faster with Bash (2015) by W0lf on Thursday April 22, 2021 @05:16AM (#26900549)

For this exact use case I defined the following many years ago in my bash profile:

    # create a new directory and enter it
    function mkd() {
        mkdir -p "$@" && cd "$_";
    }

And use it like: mkd foo

Beware that using "$@" there might not be what you want, as it passes space-separated arguments to mkdir.

What does: "mkd foo bar" do? It creates both directories, and cd's into "bar".

Might be worth checking that only one argument has been passed, or use "$*" which instead would treat all arguments as one parameter, and "mkd foo bar" would create a "foo bar" directory instead (and cd to it)

YMMV.

Thanks a lot for pointing this out. I will happily fix this now!

All Bash manuals and tutorials should start from explaining this issue. And I really mean it. I can't remember how many times I was bitten by it until I finally read it up.

I feel one should also install shellcheck, and follow it religiously while looking up every warning they get - to understand what it's about, why it's a problem, and why the solution / "correct" incantation is so.

It's also a good way to "learn by doing", which works for many.

I still have to read it up from time to time even though I know it already. The difference is huge.
