SHOW TERMINAL

Displays the current characteristics of a specific terminal. Each characteristic corresponds to an option of the SET TERMINAL command.

Format

SHOW TERMINAL [device-name[:]]

Parameter

device-name[:]
Specifies the name of the terminal for which you want the characteristics displayed. The default is your terminal (SYS$COMMAND).

Description

The SHOW TERMINAL command displays the information about terminal settings for such things as terminal speed, width, number of lines, graphics, and device type.
Note that the SHOW TERMINAL command does not describe terminal fallback characteristics if any are activated. If the Terminal Fallback Facility (TFF) is enabled, you can invoke the Terminal Fallback Utility (TFU) and issue the subcommand SHOW TERMINAL/FALLBACK. For more information, see the OpenVMS Terminal Fallback Utility Manual (available on the Documentation CD-ROM).

Qualifiers

/BRIEF
Displays a subset of more commonly used terminal characteristics.
/FULL (default)
Displays all terminal characteristics.
/OUTPUT[=filespec]

/NOOUTPUT
Controls where the output of the command is sent. If you do not enter the qualifier, or if you enter the /OUTPUT qualifier without a file specification, the output is sent to the current process default output stream or device, identified by the logical name SYS$OUTPUT.
If you enter the /OUTPUT qualifier with a partial file specification (for example, specifying only a directory), SHOW is the default file name and .LIS the default file type. If you enter a file specification, it cannot include the asterisk (*) and the percent sign (%) wildcard characters.
If you enter the /NOOUTPUT qualifier, output is suppressed.
/PERMANENT
Requires LOG_IO (logical I/O) or PHY_IO (physical I/O) privilege.
Displays the permanent characteristics of the terminal.

In this example, the SHOW TERMINAL command displays the characteristics of this specific terminal. If you are displaying statistics about a terminal allocated to another user, the input, output, LFfill, CRfill, width, page, and parity statistics are not shown (see the next example).
