# `rename`

> **Note:** this page refers to the command from the `util-linux` package on Linux or Homebrew's `rename` package.

## TL;DR

```sh
# Show what would change without changing anything (dry run).
rename -vn foo bar *

rename -n 's/^(\d{4}-\d{2}-\d{2})  (.*)$/$1  addition  $2/' 'file'
rename -n 's/^What.*(\d{4}-\d{2}-\d{2}) at (\d{2}\.\d{2}.\d{2}\..*)/$1 $2/' *
```
