If Options \begin{math}\rightarrow\end{math}Completed tasks is not checked, the task will disapear when you mark it completed. but do not worry, it is not gone forever, just check Completed tasks in the options menu, and you can see and edit it again. \chapter{File Manager} The file manager allows easy access to your file system, letting you browse, copy, move, delete and link files. You can also use it to open the file in an application based upon the file type, or add the file to your ``Documents'' tab, as well as several other filesystem related things. \section{Navigating} To enter a directory, simply press its icon or name in the main view. There are also two buttons in the toolbar which help with navigation. The back arrow will take you back to the directory you were previously looking at, while the up arrow will take you up one level in the directory structure (so, if you are in /usr/bin, it will take you to /usr, regardless of where you were before). The ``Dir'' menu shows the current path, with each directory as a menu item. So, if you are in /opt/QtPalmtop/bin there will be four entries: /, opt, QtPalmtop, and bin. Selecting one of these will take you immediately to that directory. \section{Selecting Files} When you click on a file, its selection status is toggled. So the first time you click on it, it will be selected, and the second time it will be deselected. To select multiple files, simply click on each one you want to select. \section{Moving Files} To copy a file from one directory to another, press and hold on the filename, and select ``Copy'' from the menu that pops up. Then, change into the directory that you want to copy it into, and press the "paste" icon (an image of a clipboard and a piece of paper). To move a file, do the same thing, except select ``Cut'' from the first menu, instead of ``Copy''. You can also move or copy multiple files by selecting all of them and using the cut or copy buttons in the toolbar. \section{Deleting Files} To delete a file, press and hold it to bring up its menu, then select ``Delete'', and click ``Yes'' (or ``No'' to cancel). Delete will delete all the currently selected files, which may be more than the one that you pressed and held on. \section{Renaming Files} To change a file's name, first bring up the input method you want to use (unless you are going to use the hardware keyboard), then press and hold on the filename, and select ``rename''. A new file will appear with a ``Name'' field that is editable, enter the new name, and click another file to keep the new name. \section{Creating Directories} To create a directory, first bring up the input method you want to use (if you are using one), and then click the new directory button (an image of a file folder with a ``+'' sign). A new folder will be created with the name ``New Folder'', and the folder name will be editable. Enter the name you want and then click another file to create the folder. \section{Viewing Files} To view a file, press and hold on a file, and the menu that comes up will contain two entries for vieing the file, the first depends on the filetype, but usually lets you open the file in a specific program. The second is ``view as text'' which will open the file up in TextEdit (regardless of whether or not it is actually a text file). \section{Adding to ``Documents''} \label{docadd} To add a file to your ``Documents'', press and hold the file, and select ``Add to documents'' from the menu. This will add the file to the documents tab, which you can use to quickly open the file (simply click on the icon for the file in the Documents tab). Some programs also use the Documents list to aid in quickly opening files. \section{Sorting Files} To sort the files, use the ``Sort'' menu to select wich field you want to sort the files by (``by Name'', for instance, will sort the file alphabetically by name). If ``Ascending'' is checked, the files will be sorted in ascending order, if it is not, they will be sorted in descending order. You can also press the name of the column in the main view to sort by that field. \section{Viewing Options} The ``View'' menu lets you choose which files to view. If ``Hidden'' is checked, hidden files will be visible (in Linux, hidden files start with a ``.''). If ``Symlinks'' is checked, symbolic links (files or directories which are merely links to other files or directories) will be visible. \chapter{Embedded Konsole} EmbeddedKonsole is Opie's terminal emulator. From here you can do pretty much anything (since Linux is actually a command line based OS by itself). I will not go into much detail on using the linux command line, as that is covered in many other places (http://www.tldp.org is a good place to start, or read O'Reilly's \underline{Running Linux} for a comprehensive look at Linux for the beginner). I will, however, give a quick overview of using a Linux shell. \section{Using Embedded Konsole} Along the top of the window is a row of menus and icons. The ``Font'' menu lets you select the font size that you want the console to use, while the Options menu lets you select various options. Below this row of menus and icons is a pulldown list with various common commands in it. \subsection{Options Menu} The first submenu in the options menu is the ``Command List'' menu, which lets you edit or hide the command list pulldown. The ``Tabs on top'' or ``Tabs on bottom'' (depending on which is currently enabled) allows you to select where the tabs representing multiple terminal sessions are drawn. The ``Colors'' submenu lets you select from a color scheme, or make your own, and the ``Scroll Bar'' submenu lets you select where or if the scroll bar is drawn. \subsection{Icons} The row of icons to the right of the menus allows you to type common keystrokes without having an input method visible, as well as some other things. The icon all the way on the left will open a new terminal session in a new tab, while the icon all the way on the right will paste text from the clipboard into the terminal. The other icons are the same as typing (from left to right) enter, space, tab (for tab completion), up, and down (for the command history). \subsection{Command List} The command list is a pulldown menu with a list of commonly used commands. Selecting one will type the command into the terminal wherever the cursor is. You can edit or hide this menu from Options \begin{math}\rightarrow\end{math}Command List. \section{What is a Shell} A shell is a program that accepts input from a user, and runs commands. 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. \section{Running Programs} 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 \verb+./program+ (``./'' is a special directory that is explained below), or to run a program in /home/username/ you would call \verb+/home/username/program+. Most programs take ``arguments'' when run from the command line. An argument is a string that contains no spaces that changes how the program behaves (a text editor, for instance, might take a single argument, which would be the name of the file you wish to edit). Usually, you can use the arguments ``-h'' or ``--help'' to get a list of the common arguments that that program takes, along with a short usage description, and a short description of what each argument does. \section{Basic Navigation} The command that you will use most often in the shell is probably the ``cd'' command, which stands for ``change directory.'' With this command, you can move around in the file system, by issuing the command like this: \verb+cd [new directory]+, where \verb+[new directory]+ is the directory you want to move to. This directory name does not have to include the entire directory structure, but can be ``relative'' which means it assumes you are talking about directories relative to the directory you are in. For example, if you are in a directory called /home/username and you want to move to the directory /home/username/other/dir you could simply type \verb+cd other/dir+ and you would end up in /home/username/other/dir. You can also specify a full, or ``absolute'' path, by specifying the entire path name starting with / ( / is a special directory called the ``root'' directory, and does not have a ``parent'' directory, which means that it is not in any other directory). There are also two special directories called ``./'' and ``../''. The ``./'' directory is the current directory you are in, and you will probably never use this in conjunction with the cd command (why would you want to move to the directory you are already in?). The ``../'' directory represents the parent directory of the directory you are currently in, so if you are in /home/username, ../ is the same as /home. You can string several ../'s together, so if you are in /home/username/dir/ ../../ represents /home. There is one other special directory, called ``$\sim$/'' that points to your home directory (usually /home/username or /root for the root user). \section{Moving Files} To move files around, you need to use the ``cp'' (copy) and ``mv'' (move) commands. Both of these are run the same way: \verb+command originalfile newfile+. The only difference is that cp creates a new file without touching the old one, while mv deletes the original file. The two path names can be either absolute or relative. If you only specify a directory for the destination, and no filename, it will use the filename for the original file. \section{Deleting Files} To delete a file, run the ``rm'' command, and to delete a directory, run the ``rmdir'' command, each of them take the file to be removed as their only argument. The rmdir command requires the directory to be empty, so if you want to delete a directory that is not empty, along with all its contents, run \verb+rm -r dir+. \section{Linking Files} In Linux, you can have a special file called a ``symbolic link'' that acts just like a copy of another file, except it takes up less space. 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: \verb+ln -s originalfile link+. + +\part{Settings} +\chapter{Software} +%This section needs a lot of work, describing things like destinations, feeds, etc, but this should probably be added after oipkg works properly. + +The ``Software'' application, also called oipkg, is what is used to install and remove software. It is actually a frontend to the command line program ``ipkg'' so most things you can do with oipkg you can also do with ipkg. Oipkg can install things either remotely from a web server (called a ``feed'') or it can install an ipkg package file that resides on the local filesystem. + +Note: There is a bug in oipkg that prevents it from installing packages properly. There is, however, a workaround for it. Simply run oipkg from Embedded Konsole to avoid the bug. + +\section{Installing Software} + +To install software, first select ``Opie'' from the ``Section'' pulldown menu, the press the ``+'' icon next to ``Feeds'' in the main view. This will show all the available Opie packages (you can change which packages to view by selecting something else from the ``Section'' pulldown). Installed packages are marked with a blue circle, while packages that are not installed are marked with a red box. If you click on the icon for an uninstalled package, it will turn into an open box, with a blue circle coming out of it, indicating that you have marked this package to be installed. Mark as many packages as you wish this way, and then press the ``Apply'' icon (same red box and blue dot icon) to install all the marked packages. It will also remove any packages marked for removal (see below). Clicking this will open a window showing all the packages marked to be removed and installed, with some check boxes on the bottom, which represent arguments to be sent to ipkg, which you can usually ignore. After verifying that all the packages to be installed are correct, press ``Ok'' in the upper right corner (or press ``x'' to cancel and go back to the package selection window). The packages should then install, and you should see their icons appear in the Launcher, if they are Opie applications. + +\section{Removing Software} + +Removing software is the same as installing software, except you will press the blue circle icon of an installed package, and it will have a red ``X'' over it. Then press the apply icon, and ``Ok''. You can install and remove packages at the same time by marking the ones you want to install and the ones you want to remove, and then pressing apply. \end{document}
