Yes, they're generally available in some form (now generally including the ‘originals’ now that V8–V10 have been published). And they're all very simple, which is the whole point of Unix tools.

I've found I'm using the `put`/`take` pair, for splitting a pipeline across shells, more again in the WFH era where I often have multiple ssh sessions into a machine, when I would probably have used the clipboard in a GUI session. Also useful for things like seeing stderr from different parts of a pipeline in different windows. `put` is just `cat >>$(mkpipe "$1")` and `take` is `cat $(mkpipe "$1")` where `mkpipe` is

    fifo="${TMPDIR:-/tmp}/fifo-$(id -u)-$1}"
    test -p "$fifo" || mkfifo "$fifo"
    echo "$fifo"

Not all Unix tools are simple. E.g. make. But I know what you mean - the Unix philosophy.

The TAOUP book by Eric Raymond (The Art Of Unix Programming) has a lot about that.

And my IBM developerWorks tutorial / case study on Developing a Linux command-line utility (in C) may be of interest to people who want to write their own Unix tools that play well with others.
