@(#)cap_mkdb.1 8.1 (Berkeley) 6/6/93
.Dd June 6, 1993 .Dt CAP_MKDB 1 .Os .Sh NAME .Nm cap_mkdb .Nd create capability database
p .Sh SYNOPSIS .Nm .Op Fl b | Fl l .Op Fl v .Op Fl f Ar outfile .Ar file1 .Op Ar file2 ...
p .Sh DESCRIPTION .Nm builds a hashed database out of the .Xr getcap 3 logical database constructed by the concatenation of the specified files .
p The database is named by the basename of the first file argument and the string .Dq .db . The .Xr getcap 3 routines can access the database in this form much more quickly than they can the original text file(s).
p The ``tc'' capabilities of the records are expanded before the record is stored into the database.
p The options are as follows: l -tag -width XXXXXX -indent t Fl b Use big-endian byte order for database metadata. t Fl f Ar outfile Specify a different database basename. t Fl l Use little-endian byte order for database metadata. t Fl v Print out the number of capability records in the database. .El
p The .Fl b and the .Fl l flags are mutually exclusive. The default byte ordering is the current host order.
p .Sh FORMAT Each record is stored in the database using two different types of keys.
p 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.
p 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 a 2.
p 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. .Sh EXIT STATUS The .Nm utility exits 0 on success and >0 if an error occurs. .Sh SEE ALSO .Xr dbopen 3 , .Xr getcap 3 , .Xr termcap 5
