They have to an extent. The /proc file system on Linux is directly inspired by plan 9 IIRC. Other things like network sockets never got that far and are more related to their BSD kin.

Not at all, /proc comes from Solaris.

Looking into it we are both wrong. Plan 9 implemented /proc after 8th edition Unix. Solaris and Linux both implemented it at the same time in 1992.

There's also /dev/tcp in Linux

    exec 5<>/dev/tcp/www.google.com/80
    echo -e "GET / HTTP/1.1\r\nhost: www.google.com\r\nConnection: close\r\n\r\n" >&5
    cat <&5

/dev/tcp does not exist in Linux.
ls /dev/tcp
It is an abstraction in GNU Bash.
