Ups... be my guest then ;)

Let's try to archive file file.txt:
me@ember:~$ ls -l file.txt*
-rw-r--r-- 1 me users 21 Apr 18 12:06 file.txt
me@ember:~$ tar cf ./file.txt.tar ./file.txt
'f' option allowed us to specified the name of the archive file and place
where we want to put the archive file.
me@ember:~$ ls -l file.txt*
-rw-r--r-- 1 me users 21 Apr 18 12:06 file.txt
-rw-r--r-- 1 me users 10240 Apr 18 12:08 file.txt.tar
Ok, seems to have tar working for us. :)
Let's try to not specify 'f' in the tar command:
me@ember:~$ tar c ./file.txt.tar ./file.txt
tar: can't open /dev/sa0: Device not configured
Oops! tar tried to open non existent device to put archive file in there as
it has said that in the default configuration which doesn't require to
specify anything with 'f' option it should work in this way. :)
As I said in the part of jar manual it works similar. Instead of default set
to the archive device jar has your screen as the default.
Hope you understood my english and I am not mistaken about the manuals ;)
