NAME

ppdduprev - uprevs ppdd data  

SYNOPSIS

This program allows the user to bring data on an existing ppdd device into line with any format changes between revisions.  

DESCRIPTION

The program takes exactly three arguments:
the old revision, the new revision and the file or device name.  

e.g. ppdduprev 0.7 0.9 /dev/hda3  

Depending on the revision levels it may ask for a pass phrase and it may also take a long time. Some revision changes are however very quick. In any case the program should not be interrupted.  

Supported levels

If the program is run without any arguments it displays a help message including the supported revision levels.
Currently 0.7 to 0.8, 0.7 to 0.9 and 0.8 to 0.9 are supported.  

RETURN VALUE

The program returns 0 if it worked correctly.
The program returns 1 if anything has gone wrong.
 

ERRORS

All ppdd utilities display fairly meaningful errors (mostly on stderr). In all cases the errors have a unique error number to help locate the problem in the source code. If an error message is not clear then best source of explanation at this stage is the source itself.  

ENVIRONMENT

The program does not use any environment variables.  

FILES

Files (and devices) are specified as arguments.
