# Change To That New Directory
|
|
|
|
The `$_` variable provided by bash is always set to the last argument of the
|
|
previous command. One handy use of this is for changing directories into a
|
|
newly created directory.
|
|
|
|
```bash
|
|
$ mkdir new_dir && cd $_
|
|
```
|
|
|
|
This command will leave you in your newly created directory, `new_dir`.
|
|
|
|
We can imagine using this bash variable in a number of similar scenarios as
|
|
well. What if we are using some language specific command that creates a
|
|
directory? Will it work when creating a new Phoenix or Rails project?
|
|
|
|
It sure will.
|
|
|
|
Give it a try with Phoenix:
|
|
|
|
```bash
|
|
mix phx.new my_app && cd $_
|
|
```
|
|
|
|
or with Rails:
|
|
|
|
```bash
|
|
rails new app && cd $_
|
|
```
