# autoview

Print the content of the pipeline as a table or list.
It is the implied or default viewer when none is provided.

When reading a single value, a table or a list, `autoview` will attempt to view it.
When reading a string that originally comes from a source file it will attempt
to use `textview`.
When reading a binary file it will attempt to display its content as hexadecimal
numbers and the corresponding characters.

`-h`, `--help`
  Display help message.

## Examples

In all following examples `autoview` can be removed with no change in the output.
The use of `autoview` at the end of the pipeline is implied when no viewer is
explicitly used.

```shell
> which nu | get path | autoview
/home/me/.cargo/bin/nu
```

```shell
> ls | autoview

```shell

> open file.md | autoview
# Hi

Some text
```

`autoview` will use `textview` to colorize the text based on the file format.
The style used by `textview` can be configured in `config.toml`.

```shell
> open --raw $(which nu | get path) | autoview
