-f file |
If the ‘‘-f’’ flag is used, then the database files are named
file.dir,
file.index, and
file.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 |
The program 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.)
For more information, see the discussion of
dbzfresh and
dbzsize in
dbz(3).
