ex (stands for extended) is a text editor in Linux which is also termed as the line editor mode of the vi editor. This editor simply provided some editing commands which has greater mobility. With the help of this editor, a user can easily move between files. Also, he/she has a lot of ways to transfer the text from one file to another. A user can quickly edit blocks of text larger than a single screen and also can make substitutions throughout a file for a given pattern by using the global replacement.
