And for the commands that do not take a filename as an argument, you can do:

$ command < file

or

$ nc -l -p 6666 < file

Regarding tar, by default it uses STDIN, so -f - is the default behavior. Therefore, these two commands do the same thing:

$ tar -c /data
$ tar -cf - /data

(Ditto with the tar -x)

All in all, great article! Thanks.
