TWPRINT(8)						      System Manager's Manual							TWPRINT(8)

NAME

       twprint - Tripwire database and report printer

SYNOPSIS

       twprint { -m r | --print-report } [ options... ]
       twprint { -m d | --print-dbfile } [ options... ]
	     [ object1 [ object2... ]]

DESCRIPTION

       Prints Tripwire database and report files in clear text format.

   Report Printing mode
       In Report Printing mode, twprint verifies and displays the contents of a Tripwire report file (.twr).  If no report is specified on the
       command line, the report specified in the REPORTFILE variable in the configuration file will be used.  By default, this value includes the
       date and time to the nearest second.  Because this value is constantly changing, twprint may not be able to find the correct report file.
       For this reason, the (-r or --twrfile) flag should be used with the desired report name to print a specific report.

   Database Printing mode
       This option is used to print a Tripwire database file in human-readable (clear text) form.  In Database Printing mode, twprint verifies and
       prints the contents of a specified database to stdout.  If no database file is specified on the command line, the default database
       specified by the DBFILE variable in the configuration file is used.

	   -L localkey	      --local-keyfile localkey

       -t level, --report-level level

       [ object1 [ object2... ]]
	      List of filesystem objects in the database to print. If no objects are specified, every object in the database will be printed. The
	      format for a list of objects is: section: objname objname... section: objname...
