Functions

Create a directory and change into it at the same time

Terminal - Create a directory and change into it at the same time
md () { mkdir -p "$@" && cd "$@"; }

Create a directory and change into it at the same time

How often do you make a directory (or series of directories) and then change into it to do whatever? 99% of the time that is what I do.

This BASH function 'md' will make the directory path then immediately change to the new directory. By using the 'mkdir -p' switch, the intermediate directories are created as well if they do not exist.

Alternatives

There is 1 alternative - vote for the best!

Terminal - Alternatives
mkdir /home/foo/doc/bar && cd $_

The biggest advantage of this over the functions is that it is portable.

function mcd() { [ -n "$1" ] && mkdir -p "$@" && cd "$1"; }

I find that I create a directory and then cd into that directory quite often. I found this little function on the internets somewhere and thought I'd share it. Just copy-paste it into you ~/.bash_profile and then `source ~/.bash_profile`.

alias md='mkdir -p'; alias rd='rmdir'; mcd () { mkdir "$@" && cd "$_"; }

I realise that this is just a reiteration of another entry (regardless of whether I came up with all this all by myself), but I would like present my additional alias' in context as a method of managing your directories. Rather convenient.

function mkdcd () { mkdir "$1" && cd "$1" }
echo 'mkcd() { mkdir -p "$@" && cd "$_"; }' >> ~/.bashrc

combines mkdir and cd

added quotes around $_, thanx to flatcap!

Know a better way?

If you can do better, submit your command here.

What others think

This command does not work if the directory has embedded space:

mcd "foo bar"

To fix:

function md () { mkdir -p "$@" && cd "$@"; }

Thanks!

you are correct and I fixed it...

Comment by drewk 238 weeks and 6 days ago

I would remove the redundant and bash specific "function" keyword. I use this in my .bashrc which I've commented on here:

Comment by pixelbeat 238 weeks and 5 days ago

Done!

I usually like to use "function" because it aids interpreting what a function is. I don't have to notice the parens. But it is BASH specific... Liked your web site.

Comment by drewk 238 weeks and 5 days ago

You may want to switch the second one to $_ instead of $@

md() { mkdir "$@" && cd "$_"; }

That way if you want to add some options to mkdir, such as -p to make parents or -m to set mode, they'll get passed to mkdir without blowing up cd.
