# Interacting with the client
|
||
|
||
`dagger.#Plan` has a `client` field that allows interaction with the local machine where the `dagger` command line client is run. You can:
|
||
|
||
- Read and write files and directories;
|
||
- Use local sockets;
|
||
- Load environment variables;
|
||
- Run commands;
|
||
- Get current platform.
|
||
|
||
## Accessing the file system
|
||
|
||
You may need to load a local directory as a `dagger.#FS` type in your plan:
|
||
|
||
```cue file=../tests/core-concepts/client/plans/fs.cue
|
||
```
|
||
|
||
It’s also easy to write a file locally:
|
||
|
||
```cue file=../tests/core-concepts/client/plans/file.cue
|
||
```
|
||
|
||
## Using a local socket
|
||
|
||
You can use a local socket in an action:
|
||
|
||
import Tabs from '@theme/Tabs';
|
||
import TabItem from '@theme/TabItem';
|
||
|
||
<Tabs defaultValue="unix" groupId="client-env">
|
||
|
||
<TabItem value="unix" label="Linux/macOS">
|
||
|
||
```cue file=../tests/core-concepts/client/plans/unix.cue
|
||
```
|
||
|
||
</TabItem>
|
||
|
||
<TabItem value="windows" label="Windows">
|
||
|
||
```cue file=../tests/core-concepts/client/plans/windows.cue
|
||
```
|
||
|
||
</TabItem>
|
||
</Tabs>
|
||
|
||
## Environment variables
|
||
|
||
Environment variables can be read from the local machine as strings or secrets, just specify the type:
|
||
|
||
```cue file=../tests/core-concepts/client/plans/env.cue
|
||
```
|
||
|
||
## Running commands
|
||
|
||
Sometimes you need something more advanced that only a local command can give you:
|
||
|
||
```cue file=../tests/core-concepts/client/plans/cmd.cue
|
||
```
|
||
|
||
:::tip
|
||
You can also capture `stderr` for errors and provide `stdin` for input.

||

|
||
|
||
## Platform
|
||
|
||
If you need the current platform though, there’s a more portable way than running `uname` like in the previous example:
|
||
|
||
```cue file=../tests/core-concepts/client/plans/platform.cue
|
||
```
