This configures the eslint config to allow ES6 features. This fixes some lint errors caught in the new config, but this mostly suppresses new warnings.

//@ ### ShellString.prototype.to(file)
|
|
//@
|
|
//@ Examples:
|
|
//@
|
|
//@ ```javascript
|
|
//@ cat('input.txt').to('output.txt');
|
|
//@ ```
|
|
//@
|
|
//@ Analogous to the redirection operator `>` in Unix, but works with
|
|
//@ `ShellStrings` (such as those returned by `cat`, `grep`, etc.). _Like Unix
|
|
//@ redirections, `to()` will overwrite any existing file!_ Returns the same
|
|
//@ [ShellString](#shellstringstr) this operated on, to support chaining.
