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