moveSync(src, dest[, options])

Moves a file or directory, even across devices.

• src <String>
• dest <String> Note: When src is a file, dest must be a file and when src is a directory, dest must be a directory.
• options <Object>
  • overwrite <boolean>: overwrite existing file or directory, default is false.

Example:

const fs = require('fs-extra')

fs.moveSync('/tmp/somefile', '/tmp/does/not/exist/yet/somefile')

Using overwrite option

const fs = require('fs-extra')

fs.moveSync('/tmp/somedir', '/tmp/may/already/exist/somedir', { overwrite: true })
