you're just fine. I have a habit of being *in* the dir that I want to tarball, and put the ball one up. For example:
tar -czvf ../all.tar.gz *
... this is because I often want the 'ball to just have the files in the root, not in a subdir when I spit it back out. Could be that I have my head up my butt though.

../ means "one above where I currently am" ./ means "right here in this damn directory."

So what does the ./ mean in i guess when you
run a file from somewhere else, like ./usr/games/fortune

./usr/games/fortune
is the same as
usr/games/fortune
... it means "from right here." but not the same as
/usr/games/fortune
which means from the root and
../usr/games/fortune
which would mean, go UP one directory, then down into the usr/games and run fortune.

to explain anotherway.
. = here
.. = parent
/ =directory
so ./ = here-directory, which is redundant and blabbery. the . alone is the important part really. same thing with ..
if you type>> cd .
you wont go anywhere.
type>> cd ..
and you go up 1 dir
type>> cd /
and you end up at root
type>> cd ./
you just typed 1 more char than you needed to.

Actually, 5: c d . / [enter] ... because that command does exactly... nothing  |

cd -
goes to the directory in which you previously were, regardless of your current location and
cd ~
goes to your home directory, though if you type cd ~ and then hit tab, it will spell out your home directory's full path.
./ may be redundant, but the superstitious UNIX sysadmin in me always does it to execute shell scripts anyway. Don't ask me why.

Well, isn't the local directory after the defined constants in the shell? So if you
root# ./myscript.sh
and
root# myscript.sh
... you're actually in an (unlikely but possible) situation where there is a script in the search path named myscript.sh that would be found and executed before the one in your current directory... I think anyway. I always do ./myscript as well, because it's really clear to the shell what I want.

Well yeah if you have like a myscript.sh in your /bin or /usr/bin
That's probably why I do it, I had just forgotten the reason long ago.

Not sure if it is so much in vogue anymore. Big thing in ancient days before www was to make a script of some common name like lets say "ls" Then place it in some directory like "/tmp" then when administrator logged in, if he did not have his path set correctly, then it would execute your ls (which would call the real one) and u could steal root priviledges. Big thing in those days was to make directories called like ".../.../..." and the hide warez in them on FTP sites |

Here is a one-liner: tar -cvzf /path_name_of_tarball/bakup.2009.4.28.tgz -C /path_name_of_dir . With "-C" you cd into the directory. The "." at the end is important. It means that all files from that directory will be packed into the tarball. |
