The uuxqt program is used to execute execute files generated by uux. The uuxqt program may be started by either the uucico or uux programs. The program scans the spool directory for execute files (prefix ``X.''). Each one is checked to see if all the required files are available and if so, the command line or send line is executed.
The execute file is described in the ``Uux'' section above.
The execution is accomplished by executing a sh -c of the command line after appropriate standard input and standard output have been opened. If a standard output is specified, the program will create a send command or copy the output file as appropriate.
