makedbz - Rebuild dbz files


   makedbz [-io] [-f filename] [-s size]


   makedbz rebuilds dbz(3) database.  The default name of the text file is
   pathdb/history; to specify a different name, use the -f flag.


   -f filename
       If the -f flag is used, then the database files are named
       "filename.dir", "filename.index", and "filename.hash".  If the -f
       flag is not used, then a temporary link to the name "history.n" is
       made and the database files are written as "history.n.index" ,
       "history.n.hash" and "history.n.dir".

   -i  To ignore the old database, use the -i flag.  Using the -o or -s
       flags implies the -i flag.

   -o  If the -o flag is used, then the temporary link to "history.n" (or
       the name specified by the -f flag) is not made and any existing
       history files are overwritten.  If the old database exists, makedbz
       will use it to determine the size of the new database.

   -s size
       makedbz will also ignore any old database if the -s flag is used to
       specify the approximate number of entries in the new database.
       Accurately specifying the size is an optimization that will create
       a more efficient database.  Size is measured in key-value pairs
       (i.e. lines).  (The size should be the estimated eventual size of
       the file, typically the size of the old file.)
