# Command Snippets

> Save and reuse commands across terminal sessions.

Snippets reduce repetitive typing and help standardize frequent operations.

## Features

* Create, edit, and delete snippets
* Organize commands by purpose
* Use dynamic values/placeholders for reusable commands
* Run snippets in active terminal sessions

## Good Snippet Categories

* deploy/restart commands
* health checks
* log inspection commands
* environment bootstrap commands

## Writing Tips

* Use action-oriented names (`Restart API`, `Tail Nginx Error Log`)
* Prefer explicit flags over ambiguous defaults
* Use placeholders for values that change between environments
* Keep production-impacting commands clearly labeled

## Dynamic Values (Runtime Injection)

Use placeholders directly in the command, for example:

```bash theme={null}
ssh {USER}@{HOST} -p {PORT}
```

How it works:

* Placeholders use `{NAME}` format
* Supported names are uppercase letters and underscores (`{HOST}`, `{DB_USER}`)
* Values are requested in a dialog when you click **Run**
* All values are required before command execution

Notes:

* Replacement happens at run time, not when saving the snippet
* **Paste** is available only for snippets without placeholders
