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.

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

> ls | autoview
