Installation
gedit is located in Ubuntu's Main repository and is installed by default. gedit can be installed in Kubuntu, Xubuntu and other distributions although additional libraries are necessary and will be installed on non-GNOME systems. To install gedit:
- Select gedit in Synaptic (System → Adminstration → Synaptic Package Manager)
- From a terminal or ALT-F2:
sudo apt-get install gedit
Opening gedit
gedit incorporates a graphical user interface (GUI) and is opened by going to Applications → Accessories → Text Editor or by pressing Alt+F2 and typing gedit
Command Line Tips
Opening gedit via the command line allows the user to take advantage of several options unavailable from the GUI menu. If a path is not included in the startup command, gedit will look for the file in the current directory. If the file is not found, gedit will open a blank file with the file name entered on the command line:
- To open a specific file:
gedit filename
- To open multiple files:
gedit file1 file2
- To edit system files such as sources.list and fstab, open it with administrative privileges. Note graphical applications use gksudo rather than sudo.
gksudo gedit
- To open at a specific line number, useful when an error message includes the line number, include "+<line number>". (gksudo is used in this example since the file is a system file owned by root):
gksudo gedit +21 /etc/apt/sources.list
Configuration Options
Several popular options which the user may wish to review after the initial installation are:

- Spell Checker: Edit → Preferences → Plugins tab. This feature is enabled by default.
Plugins

Plugins greatly enhance the power of gedit and are are accessed via Edit → Preferences → Plugins. More than a dozen plugins are pre-installed and can be enabled/disabled in this section. Some of the most popular are enabled by default while others must be enabled by the user.
- Tag List. Displays common tags in a side pane and allows for easy insertion into the file.
- External Tools. One of the powerful default plugins available (but not enabled by default), External Tools allows the user to run external commands on the file being edited from within gedit itself.
- Once this plugin is enabled, the user can select custom tools from the Tools menu.
- The addition of shortcut keys and the configuration of tools from the External Tools Manager are accomplished via the Tools → External Tools... menu.

Using gedit for XML / Docbook XML
