Multiple shell management with GNU Screen

"Harry Potter may have his wand, Thor may have Mjöllnir, and Buckethead may have his axe, but all those gizmos pale in power to the QWERTY. With a few taps at the command line, you can launch a Web site, recruit legions to your cause, or vanquish a marauding thunder lizard.

"Alas, even the mighty QWERTY has a fatal weakness: It succumbs easily to a cut connection. A noisy phone line, a lost cellular or wireless connection, or a network time-out spells certain death for a remote shell. If you've spent hours on a task, such as debugging an application, it can be frustrating and maddening to lose your work in an instant.

"But don't smash Mjöllnir into your head. Instead, adopt GNU Screen. Screen creates and manages multiple shell windows within a console (say, a dumb terminal physically connected to the host), an xterm window, or a Secure Shell (SSH) login. You can switch from one shell window to another in a flash, and you can leave shells running perpetually and reconnect at any time. Effectively, Screen provides many virtualized consoles."
