dtach is a tiny program that emulates the detach feature of screen,
|
2010-07-01 04:02:06 +02:00
|
|
|
allowing you to run a program in an environment that is protected from
|
|
|
|
|
the controlling terminal and attach to it later. dtach does not keep
|
|
|
|
|
track of the contents of the screen, and thus works best with programs
|
|
|
|
|
that know how to redraw themselves. It is designed to be transparent and
|
|
|
|
|
un-intrusive; it avoids interpreting the input and output between
|
|
|
|
|
attached terminals and the program under its control.

dtach does not, however, have the other features of screen, such as its
|
|
|
|
|
support of multiple terminals or its terminal emulation support. This
|
|
|
|
|
makes dtach extremely tiny compared to screen, making it more easily
|
|
|
|
|
audited for bugs and security holes, and also allows it to fit in
|
|
|
|
|
environments where space is limited, such as on rescue disks.
