mvt Command


Typesets English-language view graphs and slides.


mvt [ -a ] [ -c ] [ -e ] [ -g ] [ -p ] [ -t ] [ -z ] [ -TName | -DDestination ] [ File ... | - ]


The mvt command typesets its input with the mv macro package for view graphs and slides in a manner similar to the mmt command. The mvt command has flags to specify preprocessing by the tbl, eqn, pic, cw, and grap commands. The flags you select determine which pipelines, flags, and parameters are generated for the troff command and the macro package.

The mvt command, unlike the troff command, automatically pipes its output to a postprocessor, unless specifically requested not to do so. The user should not specify a postprocessor when using the mvt command. The path that the mvt command takes is as follows:

  1. The -z flag (no postprocessor is used).
  2. The -TName flag.
  3. The TYPESETTER environment variable is read.
  4. The default is set to ibm3816.

File specifies the file that the mvt command formats.


Flags can occur in any order, but they must be displayed before the File parameter. If no file is specified, the mvt command prints a list of its flags.

-a Displays readable troff output to the terminal.
-c Calls the cw command.
-e Calls the eqn command; also causes the eqn command to read the /usr/share/lib/pub/eqnchar file.
-g Calls the grap command, which in turn calls the pic command.
-p Calls the pic command.
-t Calls the tbl command.
-z Calls no output filter (or postprocessor) to process or redirect the output of the troff command.
-DDestination Directs the output to the specified device destination. Supported value for the Destination variable is 4014, which is the Tektronix 4014 terminal by way of the tc command.
-TName Creates output for the troff device as specified by the Name variable. The output is sent through the appropriate postprocessor. The default is ibm3816.
- Forces input to be read from standard input.

Any other parameters or flags that you give the mvt command (such as the -a flag) are passed to the troff command.

The mvt command reads standard input when you specify the - (minus) flag instead of the File parameter.

Use the -oList flag of the troff command to specify ranges of pages to be output.

Note: If you call the mvt command with one or more of the -e, -c, -t, -p, -g, or - flags, together with the -oList flag of the troff command, you may receive a broken pipe message. This occurs if you do not specify the last page of the document in the List variable. This broken pipe message is not an indication of any problem and can be ignored.

Environment Variables

TYPESETTER Contains information about a particular printing device.
