# trim
|
|
|
|
Trim leading and following whitespace from text data
|
|
|
|
## Example
|
|
|
|
```shell
|
|
> echo " Hello world"
|
|
Hello world
|
|
```
|
|
|
|
```shell
|
|
> echo " Hello world" | trim
|
|
Hello world
|
|
```
|
|
|
|
Trim can also be passed a list or table of text, for which it will trim each item individually.
|
|
It will fail if any element in the list or table is not of type String.
|
|
|
|
```shell
|
|
> open greetings.json | to json
|
|
[" hi ", " hello ", " wassup "]
|
|
```
|
|
|
|
```shell
|
|
> open greetings.json | trim | to json
|
|
["hi", "hello", "wassup"]
|
|
```
|

|
|
> cargo search shells --limit 10 | lines | parse "{crate_name} = {version} #{description}"
