Here, `{}` is a placeholder for the search result. `{.}` is the same, without the file extension.
See below for more details on the placeholder syntax.
+The terminal output of commands run from parallel threads using `-x` will not be interlaced or garbled,

#### Placeholder syntax
The `-x` and `-X` options take a *command template* as a series of arguments (instead of a single string).
