`mkdir -p cool-fedi-project/{postgres-data,redis-data}`

Which creates cool-fedi-project and then both postgres-data and redis-data underneath!

@box464 You can even have that in the middle of the path, so you could have written it as mkdir -p cool-fedi-project/{postgres,redis}-data

@box464 Okay, that is *neat* and very handy. <bookmarks>

That’s a standard shell feature. A more efficient way of writing same is

mkdir -p cool-fedi-project/{postgres,redis}-data

or even

mkdir -p cool-fedi-project/{postgre,redi}s-data

It also supports ranges, e.g.,

mkdir -p cool-fedi-project/data-{0..5}

creates 6 folders. They can be combined

mkdir -p cool-fedi-project/{a..z}-data-{0..9}{0..9}

creates 2600 folders (26 from letters, 100 2-digit numbers)

mkdir -p cool-fedi-project/{a..z}-data-{0..99}

Also creates 2600 folders, but with a mix of single and double digit numbers.
