Figure 3: The tree structure of the file system
look something like the sketch in Figure 3, which shows how a user (here
s001234) might have his or her home folder placed in the global structure of
the databar system.
Immediately after logging in, you will be in your own home folder, which
is named according to your individual User ID. The user has write access to
his or her own home folder, and thus can place documents and other folders
in it.
In Figure 3 you see an example where the user s001234 has placed two
documents (dok1 and dok2) in the home folder plus one folder (bib.no.1/),
and that folder contains two more documents (brev and gml.brev).
6.5.2 UNIX commands
As mentioned before, in UNIX your work on a project can be either graphic or
command oriented. The big advantage of the command oriented use is that it is
much faster as soon as you get some practice in it. UNIX commands are keyed
in at a terminal window (see the section 6.1.2).
UNIX commands are generally written in the following syntax:
command 〈parameter〉 〈filename(s)〉
where the parameter “filename(s)” could also be “foldername”. File names can
include one or more joker characters or wild cards. Two joker characters that are
good to know are * which can stand for any other character or any sequence of
characters, and ? which can stand for a single character (note that the words
“document” and “file” mean the same thing. Sometimes we denote them as
documents, and sometimes as files.)
An example of the ls-command for listing files is
