Nu comes with a set of built-in commands (listed below).

If a command is unknown, the command will shell-out and execute it (using cmd on Windows or bash on Linux and macOS), correctly passing through stdin, stdout, and stderr, so things like your daily git workflows and even `vim` will work just fine.

||||
|
||||
If you want to pull a pre-built container, you can browse tags for the [nushell organization](https://quay.io/organization/nushell)
|
||||
on Quay.io. Pulling a container would come down to:
|
||||
|
||||
```bash
|
||||
$ docker pull quay.io/nushell/nu
|
||||
$ docker pull quay.io/nushell/nu-base
|

docker pull quay.io/nushell/nu
|
||||
docker pull quay.io/nushell/nu-base
|
||||
```

Both "nu-base" and "nu" provide the nu binary, however nu-base also includes the source code at `/code`

|
|||
To build the base image:

||||
|
||||
```bash

||||
$ docker build -f docker/Dockerfile.nu-base -t nushell/nu-base .
|
||||
docker build -f docker/Dockerfile.nu-base -t nushell/nu-base .
|
||||
```
|
||||
|
||||
And then to build the smaller container (using a Multistage build):
|
||||
|
||||
```bash
|
||||
$ docker build -f docker/Dockerfile -t nushell/nu .
|
||||
docker build -f docker/Dockerfile -t nushell/nu .
|
||||
```
|
||||
|
||||
Either way, you can run either container as follows:
|
||||
|
||||
```bash
|
||||
$ docker run -it nushell/nu-base
|
||||
$ docker run -it nushell/nu
|
||||
docker run -it nushell/nu-base
|
||||
docker run -it nushell/nu
|
||||
/> exit
|
||||
```
|
||||
|

The second container is a bit smaller if the size is important to you.

# Philosophy
|
||||
## Philosophy
|
||||
|
||||
Nu draws inspiration from projects like PowerShell, functional programming languages, and modern CLI tools.
|
||||
Rather than thinking of files and services as raw streams of text, Nu looks at each input as something with structure.
|
||||
For example, when you list the contents of a directory, what you get back is a table of rows, where each row represents an item in that directory.
|
||||
These values can be piped through a series of steps, in a series of commands called a 'pipeline'.
|
||||
|
||||
## Pipelines
|
||||
### Pipelines
|
||||
|
||||
In Unix, it's common to pipe between commands to split up a sophisticated command over multiple steps.
|
||||
Nu takes this a step further and builds heavily on the idea of _pipelines_.
|
||||
|
|
@ -138,40 +139,40 @@ Additionally, commands can output structured data (you can think of this as a th
|
|||
Commands that work in the pipeline fit into one of three categories:
|
||||
|
||||
* Commands that produce a stream (eg, `ls`)
|
||||
* Commands that filter a stream (eg, `where type == "Directory"`)
|
||||
* Commands that filter a stream (eg, `where type == "Dir"`)
|
||||
* Commands that consume the output of the pipeline (eg, `autoview`)
|
||||
|
||||
Commands are separated by the pipe symbol (`|`) to denote a pipeline flowing left to right.
|
||||

||||

```
|

|

Because most of the time you'll want to see the output of a pipeline, `autoview` is assumed.
|
||||
We could have also written the above:
|
||||
|
||||
```
|
||||
/home/jonathan/Source/nushell(master)> ls | where type == Directory
|
||||
```shell
|
||||
> ls | where type == Dir
|
||||
```
|
||||
|
||||
Being able to use the same commands and compose them differently is an important philosophy in Nu.
|
||||
For example, we could use the built-in `ps` command as well to get a list of the running processes, using the same `where` as above.
|
||||
|
||||
```text
|
||||
/home/jonathan/Source/nushell(master)> ps | where cpu > 0

### Opening files
|

Nu can load file and URL contents as raw text or as structured data (if it recognizes the format).
|
||||

|
||||
|
||||
```
|
||||
/home/jonathan/Source/nushell(master)> open Cargo.toml

||||
## Configuration
|
||||
### Configuration
|
||||
|
||||
Nu has early support for configuring the shell. You can refer to the book for a list of [all supported variables](https://www.nushell.sh/book/en/configuration.html).
|
||||
|
||||
To set one of these variables, you can use `config --set`. For example:
|
||||
|
||||
```
|
||||
```shell
|
||||
> config --set [edit_mode "vi"]
|
||||
> config --set [path $nu.path]

||||
```

||||
## Shells

||||
### Shells

# alias
|

|

This command allows you to define shortcuts for other common commands. By default, they only apply to the current session. To persist them, add `--save`.
|

|
||||
Syntax: `alias {flags} <name> [<parameters>] {<body>}`
|
||||
|
||||
The command expects three parameters:
|
||||
|
||||
* the name of alias
|
||||
* the parameters as a space-separated list (`[a b ...]`), can be empty (`[]`)
|
||||
* the body of the alias as a `{...}` block

## Persistent aliases
|
||||
|
||||
Aliases are most useful when they are persistent. For that, add them to your startup config:
|
||||
```
|
||||
|
||||
```shell
|
||||
> config --set [startup ["alias myecho [msg] { echo $msg }"]]
|
||||
```
|
||||
|
||||
This is fine for the first alias, but since it overwrites the startup config, you need a different approach for additional aliases.
|
||||
|
||||
To add a 2nd alias:
|
||||
|
||||
```shell
|
||||
> config --get startup | append "alias s [] { git status -sb }" | config --set_into startup
|
||||
```
|
||||
config --get startup | append "alias s [] { git status -sb }" | config --set_into startup
|
||||
```
|
||||
|
||||
This first reads the `startup` config (a table of strings), then appends another alias, then sets the `startup` config with the output of the pipeline.
|
||||
|
||||
To make this process easier, you could define another alias:
|
||||
```
|
||||
|
||||
```shell
|
||||
> alias addalias [alias-string] { config --get startup | append $alias-string | config --set_into startup }
|
||||
```
|
||||
|
||||
Then use that to add more aliases:
|
||||
```
|
||||
addalias "alias s [] { git status -sb }"
|
||||
|
||||
```shell
|
||||
> addalias "alias s [] { git status -sb }"

- `append` does not change a file itself. If you want to save your changes, you need to run the `save` command

- if you want to add something containing a whitespace character, you need to put it in quotation marks

Nushell works on the idea of a "pipeline". Pipelines are commands connected with the '|' character.
|
||||
Each stage in the pipeline works together to load, parse, and display information to you.
|
||||
|
||||
[Examples]
|
||||
|
||||
List the files in the current directory, sorted by size:
|
||||
ls | sort-by size
|
||||
|
||||
Get information about the current system:
|
||||
sys | get host
|
||||
|
||||
Get the processes on your system actively using CPU:
|
||||
ps | where cpu > 0

## Image Variants
|
||||
|
||||
### `nu:<version>`
|
||||
|
||||
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
|
||||
|
||||
<details><summary>example</summary>
|
||||
|
||||
Let say you create a plugin in Rust.
|
||||
|
||||
- create a Dockerfile in your root project
|
||||
|
||||
```dockerfile
|
||||
FROM nu:0.2
|
||||
|
||||
COPY /target/debug/nu_plugin_cowsay /bin/
|
||||
ENTRYPOINT ["nu"]
|
||||
```
|
||||
|
||||
- build your project first then run it via docker
|
||||
```console
|
||||
|
||||
```bash
|
||||
cargo build
|
||||
docker run -it .
|
||||
```
|
||||
|
||||
</details>
|
||||
|
||||
### `nu:<version>-slim`
|
||||
|
||||
This image does not contain the common packages contained in the default tag and only contains the minimal packages needed to run `nu`. Unless you are working in an environment where only the `nu` image will be deployed and you have space constraints, it's highly recommended to use the alpine image if you aim for small image size. Only use this image if you really need **both** `glibc` and small image size.
|
||||
|
||||
### `nu:<version>-alpine`
|
||||
|
||||
This image is based on the popular [Alpine Linux project](https://alpinelinux.org/), available in [the alpine official image][alpine]. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
|
||||
|
||||
This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use `musl` libc instead of `glibc` and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See [this Hacker News comment thread](https://news.ycombinator.com/item?id=10782897) for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.

|
|||
To minimize image size, it's uncommon for additional related tools (such as `git` or `bash`) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the [alpine image description][alpine] for examples of how to install packages if you are unfamiliar).

This image is based on [`scratch`](https://hub.docker.com/_/scratch) which doesn't create an extra layer. This variants can be handy in a project that uses multiple programming language as you need a lot of tools. By using this in [multi-stage build][], you can slim down the docker image that need to be pulled.

This image is based on [Busybox](https://www.busybox.net/) which is a very good ingredient to craft space-efficient distributions. It combines tiny versions of many common UNIX utilities into a single small executable. It also provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. Basically, this image provides a fairly complete environment for any small or embedded system.

## Bare Words
|
||||
|
||||
In Nu, bare words work the same way they do in most shells.
|
||||
|
||||
In most shells, bare words serve two purposes:
|
||||
|
||||
```
|
||||
```bash
|
||||
$ ls
|
||||
# ^^ the name of a command
|
||||
$ cat Cargo.toml

|

Consequences:
|
||||
|
||||
- Bare words cannot also refer to variables. Variable names are prefixed with `$`.
|
||||
- Bare words, in almost all contexts, cannot be keywords.
|
||||
- Numbers and operators aren't bare words.

The utility of a command's output drops off extremely rapidly after a full screen of content.
|

By default, Nu prefers to present output that can fit into a screen rather than more complete output that spans many screens.
