# lines
This command takes a string from a pipeline as input, and returns a table where each line of the input string is a row in the table. Empty lines are ignored. This command is capable of feeding other commands, such as `nth`, with its output.
## Usage
```shell
> [input-command] | lines
```
## Examples
Basic usage:
```shell
> printf "Hello\nWorld!\nLove, nushell." | lines
━━━┯━━━━━━━━━━━━━━━━
# │ value
───┼────────────────
0 │ Hello
1 │ World!
2 │ Love, nushell.
━━━┷━━━━━━━━━━━━━━━━
```
One useful application is piping the contents of file into `lines`. This example extracts a certain line from a given file.
```shell
> cat lines.md | lines | nth 6
## Examples
```
Similarly to this example, `lines` can be used to extract certain portions of or apply transformations to data returned by any program which returns a string.
