The 'env' command prints out all of the environment variables and their values.
Come up with a command that prints a list of environment variables whose names
end with either 'NAME', 'DIR' or 'PATH'.
What I've tried.
Although it highlights the part of the variables it does not list them as it should. It actually prints the whole lines including the variables. Not sure what I'm missing.

tcp-env
tcp-env(1) General Commands Manual tcp-env(1)NAME
tcp-env - set up TCP-related environment variables
SYNOPSIS
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ]
DESCRIPTION
The input for tcp-env must be a TCP connection. tcp-env finds out information about that connection, puts the information into several
environment variables as described in tcp-environ(5), and runs program with the given arguments.
Usually tcp-env is run from inetd. It might instead be run from another server that already sets up the right environment variables; if
PROTO is set to TCP when tcp-env is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
whether the input is a TCP connection.
OPTIONS -r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host.
-R Do not attempt to obtain TCPREMOTEINFO from the remote host.
-ttimeout
Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30.
