makedbz: Rebuild dbz files
makedbz - Rebuild dbz files
SYNOPSISmakedbz [-io] [-f filename] [-s size]
DESCRIPTIONmakedbz 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".
- To ignore the old database, use the -i flag. Using the -o or -s flags implies the -i flag.
- 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.)
