CAP_MKDB(1)		     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 con-
     sisting 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  fol-
     lowed 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.
