Indenting output in a shell script with pr

When printing output in a shell script, it’s quite useful to be able to indent information to group it.

The easiest way to do this is with pr, like this:

body=$(curl -s "http://localhost:8888/")
echo "Response:"
echo "$body" | pr -to 4

This generates:

        "links": {
            "games": "/games"

Given that pr appeared in version 1 of AT&T Unix, I’m late to the party with this one, but it’s a useful thing to know!
