periods in relative paths?


i have a perl script setup that says:
cgi-bin (relative)
enter relative from proframs root directory, e.g. ../cgi-bin

Well my server serves web pages out of the public_html
so my structure is /home/domain_name/public_html/cgi-bin

So what do the .. mean, would I just put /cgi-bin in this type of structure, meaning down one level of directories, or would I leave out the .'s all together in this type of structure?

Thanks,

.. stands for "one nod up in the directory tree". A single. mean "this directory". initiating something with a backslash / means "relative to the root directory", without the backslask means "relative to current directory".

Example:
/usr/share/doc is where you are now. there are, among other, directory nodes to /usr/share/doc/kde and /usr/share/doc/gnome.

../ = /usr/share
./ = /usr/share/doc
./kde = /usr/share/doc/kde (=kde)

use the cd command in a console to experiment around with this stuff. Its really basic and really important!!!

Usually the cgi-bin will be one dir up from your public_html. If you put the page that calls the script in public_html,
it should reference to .. (one dir up so we are in domain_name) and down into dir /cgi-bin
So ../cgi-bin

also look at: http://www.tldp.org/LDP/intro-linux/intro-linux.txt.gz
3.2.2. Absolute and relative paths
Code:
In relative paths we also use the . and .. indications for the current and
the parent directory. A couple of practical examples:
Hope that helps ...
