!$ is a bash variable that expands to "last
term/string/word in the previous command". When you did "ls -l
network-*", !$ would point to network-* - The last term of the
command. When you did "date", it is single-word command. So, !$ would
point to that.
When you do
$ !$
You are asking bash to execute the last term of the previous command.
It would work for date because there is an executable with such a name
in your $PATH. It wouldn't work for network-* because that is not an
executable. Thanks
