       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 link 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.)
