NAME

       makedbz - Rebuild dbz files

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

       -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.)
