cap_mkdb

CAP_MKDB(1)						    BSD General Commands Manual 					       CAP_MKDB(1)

NAME

     cap_mkdb -- create capability database

SYNOPSIS

     cap_mkdb [-v] [-f outfile] file1 [file2 ...]

DESCRIPTION

     Cap_mkdb 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 options as as follows:

     -f outfile
	     Specify a different database basename.

     -v      Print out the number of capability records in the database.

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 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 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.

RETURN VALUE

     The cap_mkdb utility exits 0 on success and >0 if an error occurs.
