# ensureDirSync(dir[,options]) Ensures that the directory exists. If the directory structure does not exist, it is created. Like `mkdir -p`. If provided, options may specify the desired mode for the directory. **Aliases:** `mkdirsSync()`, `mkdirpSync()` - `dir` `` - `options` `|` ## Example: ```js const fs = require('fs-extra') const dir = '/tmp/this/path/does/not/exist' const desiredMode = 0o2775 const options = { mode: 0o2775 } fs.ensureDirSync(dir) // dir has now been created, including the directory it is to be placed in fs.ensureDirSync(dir, desiredMode) // dir has now been created, including the directory it is to be placed in with permission 0o2775 fs.ensureDirSync(dir, options) // dir has now been created, including the directory it is to be placed in with permission 0o2775 ```
