cap_mkdb
CAP_MKDB(1) BSD General Commands Manual CAP_MKDB(1)
NAME
cap_mkdb -- create capability database
SYNOPSIS
cap_mkdb [-b | -l] [-v] [-f outfile] file ...
DESCRIPTION
The cap_mkdb utility builds a hashed database out of the getcap(3) 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 following options are available:
-b Use big-endian byte order for database metadata.
-f outfile
Specify a different database basename.
-l Use little-endian byte order for database metadata.
-v Print out the number of capability records in the database.
The -b and -l flags are mutually exclusive. The default byte ordering is the current host order.
FORMAT
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 could not 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 a 2.
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.
EXIT STATUS
The cap_mkdb utility exits 0 on success, and >0 if an error occurs.
