Users type (sometimes cryptic) +commands to perform file management, system administration, or in fact +almost anything that can be done within Linux that does not involve +graphics or video. + +For example, typing **pwd** (Print name of current/Working Directory) at +the command line in the home directory gives that location as +/home/olpc, and typing **ls** at the command line in /home/olpc in a +fresh installation of Sugar 0.94.1 in English results in this listing of +its contents. + +Where to get Terminal +===================== + +Terminal is provided with Sugar on every XO. However, by default it is +not selected for display in the Home view as a Favorite. + +- To select Terminal as a Favorite, go to Home view, then click the + List view icon. Type Te into the search box. Click the star next to + Terminal. When you switch back to the ring of icons in Home view, + Terminal will be visible. + +- Alternatively, you can leave Terminal unselected, and start it from + list view by clicking its icon or selecting Start from its hover + menu. + +If for some reason Terminal is not installed, it can be downloaded from +its [Activity +page](http://activities.sugarlabs.org/en-US/sugar/addon/4043) + +Using +===== + +- Type commands with options that modify their effects and arguments, + usually file names or other indications of where to get input and + where to put output. + +Examples: pwd and ls, as shown above + +- Chain programs together, so that the following program processes the + output of the earlier program. + +<!-- --> + + ls | grep "Sugar" + +Get a listing of the current directory, but show only lines where the +file or directory name includes the text "Sugar". The | symbol, read +pipe, represents the data link between the programs. + +- Get information on programs. For example, many commands respond to + the -h or --help options with a concise summary. + +<!-- --> + + grep -h + Usage: grep [OPTION]... PATTERN [FILE]... + Try `grep --help' for more information. + +The man and info utilities are unfortunately not available on XOs, but +will undoubtedly be included in Sugar whenever the XO of that time is +capacious enough for all of the manual and information pages in all of +the supported languages. + +The Toolbars +============ + +- Activity: Name this session, Exit +- Edit (scissors icon) Copy and Paste +- View (eye icon) Increase or Decrease font size; Full Screen +- Tabs: Open new tab; Close current tab; Next tab; Previous tab + +Learning with Terminal +====================== + +Terminal is essential to learning advanced Linux functions, such as +system administration, compiling software, and many other such topics. + +Extending Terminal +================== + +Users have the option of installing text-mode software that works in a +terminal window. Examples include text editors such as pico, or file +managers such as Midnight Commander. MC simplifies many command line +activities for the user, providing equivalents to many command in menus +and text windows. To install mc, enter + + yum install mc + +This invokes the Yellow Dog Update Manager to install the Red Hat/Fedora +package for mc, including the program, documentation, and other files. +Then the user can type mc at the command line and get a two-panel +display of files in the same or different directories, together with +function buttons and menus for creating and deleting directories, moving +or copying files, viewing or editing files, changing file permissions, +and much more. + +See the FLOSS Manuals manuals + +- [Terminal](http://en.flossmanuals.net/terminal/) about the Sugar + Terminal activity +- [Introduction to the Command + Line](http://en.flossmanuals.net/command-line/) for a user's + tutorial on command line functions + +Credits +======= + +- Sayamindu +- Wadeb +- Activity Team |
