Each "command" in the shell is actually a separate program (unless you are using a shell like BusyBox, which makes some of the more common commands part of its own program in order to save space). Shells can actually be very powerful, and many + + of them allow you to write something called "shell scripts" which are just a sequence of commands, sometimes with some flow control statements, saved to a file and run each time the script is run. For the most part, the average user does not need to know about any of this, though. If you are running Opie on the Familiar distribution, it is advisable to install the bash shell (ipkg install bash) because it offers things like tab completion, use of the backspace key, and a command history, as well as offering a more advanced scripting languauge than most other shells. </para> </section> <section><title>Running Programs</title> <para> To run a program or a command (remember, a command is just another program), you simply type the name of the program and hit "Return" (in Linux, program names do not have a special suffix like they do in windows, in fact the "." character has no special meaning unless it is at the begining of a filename, in which case it makes the file "hidden"). When you type a program name and hit "Return" the shell looks in a special list of directories called your "path", and if it cannot find it in any of those directories, it stops looking and tells you it could not find them. If you want to run a program that is not in your path, you must specify an absolute or relative path to that program. For instance, to run a program that is in the directory you are currently in, you would type <literal>./program</literal> ("./" is a special directory that @@ -125,39 +127,39 @@ directory (usually /home/username or /root for the root user). </para> </section> <section><title>Moving Files</title> <para> To move files around, you need to use the "cp" (copy) and "mv" (move) commands.

This is convinient if two applications are looking for the same file in two separate places, because the file can be in both places at once, without taking up any extra space, and any change to one is automatically applied to the other (really, there is only one file, the link is just a file pointing to the original file). This is also useful for naming applications independant of their version number. For instance, you could have a link called "application" that points to "application1.0". To create a link, use the following command: <userinput>ln -s originalfile link</userinput>. </para> </section> -</chapter>

The default destination is "/" (called "root") so +if the package says to install a file in opt/QtPalmtop/ then the file will be +installed in /opt/QtPalmtop/.
