[ale] Fun bash thing

[Charles Shapiro]

Learned this off mastodon today.

**

Here's an interesting Bash pattern I just used for the first time.

some-command <<<"$(< some/file)" >some/file

It reads all of some/file into memory before writing it to some-command's
stdin. This lets some-command's stdout be redirected to some/file without
the usual problems of reading/writing from the same file.
