# A Taste of Nu
|
||||
|
||||
Nu has built-in commands for ls and ps, loading these results into a table you can work with.

Commands are linked together with pipes, allowing you to select the data you want to use.
|
||||
|
||||
```text
|
||||
~\Code\nushell> ps | where name == chrome.exe | first 5
|
||||

|

|
||||
chrome.exe - 0.00 13432 Runnable
|
||||
----------------------------------------
|
||||
```
|
||||
|
||||
The name of the columns in the table can be used to sort the table.
|
||||
|
||||
```text
|
||||
~\Code\nushell> ls | sort-by "file type" size
|
||||
----------------------------------------------------------------------------------------
|

```
|
||||
|
||||
You can also use the names of the columns to down-select to only the data you want.
|
||||
```text
|
||||
~\Code\nushell> ls | column "file name" "file type" size | sort-by "file type"
|
