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.)
For more information, see the discussion of dbzfresh
and dbzsize in dbz(3).
