Commands Reference, Volume 2
dscreen Command
Purpose
Starts the Dynamic Screen
utility.
Syntax
dscreen [ -i InfoFile ] [ -t TermType ]
Description
The dscreen command starts the
Dynamic Screen utility, which allows a single physical terminal to be connected
to several virtual sessions, or screens, at one time.
If no flags are specified, the dscreen command reads the description for the terminal specified in the TERM environment variable from the file specified in the DSINFO environment variable. If the DSINFO environment variable is not specified, the terminal description is read
from the /etc/dsinfo file.
A terminal description typically contains the following configuration information:
- Keys used with the Dynamic Screen utility
and their function
- Number of pages of screen memory the terminal
has available
- Code sequences that must be sent or received
to access and use Dynamic Screen features
Flags
-i InfoFile |
Specifies the file that contains alternate key mappings for use with
the Dynamic Screen utility. This option is useful when the originally defined
Dynamic Screen keys conflict with one of your applications. |
|
If this flag is not specified, terminal configuration
information is read from the file specified in the DSINFO environment variable, if set. Otherwise, information is read from the
/etc/dsinfo file. |
-t TermType |
Identifies the terminal description to be read from the file containing
the key mappings. This option is useful when the desired terminal type does
not match the setting of the TERM environment variable. |
Examples
- To start the Dynamic Screen utility using
key mapping defaults, enter:
dscreen
This
sets the DSINFO and TERM environment
variables as designated in the default /etc/dsinfo
file.
- To start the Dynamic Screen utility and specify
a file that contains alternate key mappings and also identifies a terminal
description to be read from the file, enter:
dscreen -i myfile -t myterm
This uses information from a user-created dsinfo-type file named myinfo
to handle unusual key mapping needs. The myinfo
file also contains a terminal definition named myterm.
- To start the Dynamic Screen utility and specify
an alternate terminal setup, enter:
dscreen -t wy60-wp
This terminal definition (maintained in the /etc/dsinfo file) sets dscreen assigned key actions so they
do not conflict with control key command sequences in the word processing
application being used.
Files
/etc/dsinfo |
Contains the terminal descriptions for the Dynamic Screen utility. |
