How To Use X Windows Utility Gedit?

Gedit is a GNOME application that provides functionality similar to Windows Notepad. You can use it to open and change the contents of plain text files, search and replace text, and create new files.
The gedit interface is a bit spartan, but for quick editing of simple text files, it does the trick.
You can launch gedit with the command:
$ gedit &
or, if gedit is not on your path, with the command:
$ /usr/bin/gedit &
or you can click the main GNOME System menu and choose Programs > Applications > Gedit.
The interface is simple. Across the top is the tool bar with self-explanatory buttons for loading and saving files, cutting, copying, pasting and searching for text.
To load an existing file, click the Open button or choose File > Open. A dialogue box appears, where you can browse for and select a file to open.
You can save a file you have opened by clicking the Save button on the tool bar or by choosing File > Save.
The Find button on the tool bar brings up the Find dialogue box. You can also open this dialogue box by choosing Edit > Find.
Using the dialogue box is relatively simple: Fill in the text to search for and click the Find button. You can also indicate if you prefer to start your search at the beginning of the document or the current cursor position and whether or not the search should be considered case-sensitive.
Replace takes thing one step further, you can open the Replace dialogue box by selecting Edit > Replace. This dialogue box looks like the Find dialogue box except that it has an additional field for indicating the text with which to replace each found item. In addition, you can use the Replace button to indicate that you want to be prompted before replacing any text.
