NAME

       qdirstat-cache-writer - script to write QDirStat cache files from cron jobs

Usage:

       qdirstat-cache-writer [-ldvh] <directory> [<cache-file-name>]

              If   not   specified,   <cache-file-name>   defaults   to  ".qdirstat.cache.gz"  in
              <directory>.

              If <cache-file-name> ends with ".gz", it will be compressed  with  gzip.   qdirstat
              can read gzipped and plain text cache files.

       -l     long format - always add full path, even for plain files

       -m     scan mounted file systems (cross file system boundaries)

       -v     verbose

       -d     debug

       -h     help (this usage message)

       QDirStat  can read its information from cache files. This is a lot faster than reading all
       the directories in a directory tree and obtaining detailed information (size,  type,  last
       modification  time) for each file and directory with the opendir() / readdir() and lstat()
       system calls for each individual file and directory.

       QDirStat can also write those cache files ("Write Cache File..." from  the  "File"  menu),
       but  the  whole  point  of cache files is being able to do that in the background when the
       user does not have to wait for it - like in a cron job running in the middle of the night.
       QDirStat  itself  cannot  be  used  to  do  that because it is a KDE program and thus an X
       program that needs access to an X display - which cron does not provide.
