CAP_MKDB(1) OpenBSD Reference Manual CAP_MKDB(1)
cap_mkdb - create capability database
cap_mkdb [-iv] [-f outfile] file1 [file2 ...]
cap_mkdb builds a hashed database out of the getcap(3) or terminfo(5)
logical database constructed by the concatenation of the specified files.
The database is named by the basename of the first file argument and the
string ``.db''. The getcap(3) routines can access the database in this
form much more quickly than they can the original text file(s).
The ``tc'' capabilities of the records are expanded before the record is
stored into the database.
The options are as follows:
Specify a different database basename.
-i Expect the capability records to be parsed to be in terminfo(5)
-v Print out the number of capability records in the database.
Each record is stored in the database using two different types of keys.
The first type is a key which consists of the first capability of the
record (not including the trailing colon (`:')) with a data field
consisting of a special byte followed by the rest of the record. The
special byte is either a 0 or 1, where a 0 means that the record is okay,
and a 1 means that there was a ``tc'' capability in the record that
couldn't be expanded.
The second type is a key which consists of one of the names from the
first capability of the record with a data field consisting a special
byte followed by the first capability of the record. The special byte is
In normal operation names are looked up in the database, resulting in a
key/data pair of the second type. The data field of this key/data pair
is used to look up a key/data pair of the first type which has the real
data associated with the name.
