Multiple consoles, sessions, screens

Linux offers multiple consoles on the PC (or ThinkPad) display. The keys Ctrl-Alt-Fn are used to select a console. Ctrl-Alt-F1 through Ctrl-Alt-F6 produce traditional UNIX-style command lines, and Ctrl-Alt-F7 produces the X windows GUI desktop. Each of these consoles is a separate Linux session, requiring a separate login. You can log in with different userids in each session, or use the same userid in several sessions. You can switch between sessions at any time, using Cnrt-Alt-Fn keys.

You can also have multiple command line windows open on the desktop. These do not require separate logins.

Text editors

Traditional UNIX users and many Linux users regard vi as their primary text editor. Traditional mainframe users often avoid vi, if possible. The kde desktop offers the Advanced Editor, which can be started from the fountain pen nib icon in the toolbar. This is much like a simple PC text editor and very unlike vi. It is suitable for almost all the text editing we required while installing and customizing FLEX-ES. Anyone comfortable using any version of Windows or OS/2 should have no trouble using this editor. The Red Hat Linux distribution includes a number of editors, and you can select the ones you like best.
