# clipboard
|
|
|
|
> Perform copy and paste operations on the system clipboard.
|
|
|
|
Process: [Main](../glossary.md#main-process), [Renderer](../glossary.md#renderer-process)
|
|
|
|
The following example shows how to write a string to the clipboard:
|
|
|
|
```javascript
|
|
const { clipboard } = require('electron')
|
|
clipboard.writeText('Example String')
|
|
```
|
|
|
|
On Linux, there is also a `selection` clipboard. To manipulate it
|
|
you need to pass `selection` to each method:
|
|
|
|
```javascript
|
|
const { clipboard } = require('electron')
|
|
clipboard.writeText('Example String', 'selection')
|
|
console.log(clipboard.readText('selection'))
|
|
```
|
|
|
|
