Output

By default, screens are displayed to the standard output. The set output command redirects the display to the specified file or device.

Syntax:

     set output {"<filename>"}
     show output

The filename must be enclosed in quotes. If the filename is omitted, any output file opened by a previous invocation of set output will be closed and new output will be sent to STDOUT. (If you give the command set output "STDOUT", your output may be sent to a file named "STDOUT"! ["May be", not "will be", because some terminals, like x11 or wxt, ignore set output.])

When both set terminal and set output are used together, it is safest to give set terminal first, because some terminals set a flag which is needed in some operating systems. This would be the case, for example, if the operating system needs a separate open command for binary files.

On platforms that support pipes, it may be useful to pipe terminal output. For instance,

     set output "|lpr -Plaser filename"
     set term png; set output "|display png:-"

On MSDOS machines, set output "PRN" will direct the output to the default printer. On VMS, output can be sent directly to any spooled device.
