screen is a terminal multiplexor or a virtual terminal manager: it provides for multiple terminal screens from wherever you are - and allows you to put your terminals into the background in order to pick up later, right where you left off. This is a comprehensive introduction covering virtually everything in the GNU Screen Manual, as well as explaining things clearly and completely.

screen is a virtual terminal manager, which provides the UNIX and Linux console user with the ability to have multiple windows no matter where he or she might be. screen also allows detached operations, where a terminal session can be put in the background and picked up later from another location. This book is an updated copy of the Screen User's Guide as included with GNU Screen 4.0.3 in current development.

This book covers UNIX and Linux server system administration topics not extensively covered elsewhere.
