Appendix E Genfile
******************
This appendix describes 'genfile', an auxiliary program used in the GNU
tar testsuite. If you are not interested in developing GNU tar, skip
this appendix.
Initially, 'genfile' was used to generate data files for the
testsuite, hence its name. However, new operation modes were being
implemented as the testsuite grew more sophisticated, and now 'genfile'
is a multi-purpose instrument.
There are three basic operation modes:
File Generation
This is the default mode. In this mode, 'genfile' generates data
files.
File Status
In this mode 'genfile' displays status of specified files.
Synchronous Execution.
In this mode 'genfile' executes the given program with
'--checkpoint' option and executes a set of actions when specified
checkpoints are reached.
Menu
* Generate Mode File Generation Mode.
* Status Mode File Status Mode.
* Exec Mode Synchronous Execution mode.
