NAME

       atfsrepair - repair corrupted AtFS repository, or convert old repository to new format.

SYNOPSIS

       atfsrepair [-Ceinqv] file1 ...

DESCRIPTION

       Atfsrepair  checks the AtFS repository for inconsistencies in the a given file history. If
       a corrupted archive file is found in the repository, atfsrepair  tries  to  repair  it  by
       reconstructing  missing  parts  and  eliminating inconsistencies. Without a file argument,
       atfsrepair handles the complete repository. Atfsrepair is interactive and (hopefully) self
       explanatory.

       If  you  have permission problems, e.g. your AtFS repository grants group write permission
       but another user from your group can still not save data to the repository, atfsrepair  is
       also  the  right  thing  to  do.   The  programs  straightens  permission  bits within the
       repository.

       Atfsrepair automatically updates archive files,  when  the  archive  file  format  or  the
       arrangement  of  archive files within the AtFS subdirectory was changed. Before taking any
       permanent action, atfsrepair asks the user for  a  confirmation.  This  behaviour  can  be
       switched off by either the -n or the -q option (see below).

       Atfsrepair shall not be called concurrently with other applications on an AtFS repository.
       Make sure, that nobody else works on the repository  to  be  repaired  as  atfsrepair  may
       ignore existing archive locks and does not set own locks.

OPTIONS

       -C     This option causes atfsrepair to try it's hand at a derived object cache.

       -e     Edit  Mode.  Invoking  atfsrepair  with  this option rather serves for manipulating
              archive files than for repairing them.  It shall only be used by  very  experienced
              users.   For  nearly every item in the archive file, atfsrepair asks the caller for
              confirmation or modification. Beware, this level of verbosity can be very  annoying
              when the archive file is big.

       -i     Interactive mode (default).

       -n     Non-interactive  mode.  In  this mode, atfsrepair tries to repair corrupted archive
              files without human assistance. It  does  not  perform  any  user  interaction  and
              behaves  as  if  the  user  would always choose the default decision in interactive
              mode.

       -q     Quiet mode. Same as -n but also supresses all  informative  messages.   Only  error
              messages will be displayed.

       -v     Print current version number. No file processing is done.
