Code:
  
awk '/FAILED/{print p;exit} {p=p"\n"$0}' input_file | tail -50

       [--follow=system]

DESCRIPTION

       The uulog program can be used to display entries in the UUCP log file.  It can select the entries for a particular system or  a	particular
       user.  You can use it to see what has happened to your queued jobs in the past.	Different options may be used to select which parts of the
       file to display.

OPTIONS

       -#, -n lines, --lines lines
	    Here '#' is a number; e.g., `-10'.	The specified number of lines is displayed from the end of the log file.  The default is  to  dis-
	    play the entire log file, unless the -f, -F, or --follow options are used, in which case the default is to display 10 lines.

       -s system, --system system
	    Display only log entries pertaining to the specified system.

       -u, --user user
	    Display only log entries pertaining to the specified user.

       -D --debuglog
	    Display the debugging log file.

       -S, --statslog
	    Display the statistics log file.

       -F, --follow
	    Keep displaying the log file forever, printing new lines as they are appended to the log file.

       -f system, --follow=system
	    Keep displaying the log file forever, displaying only log entries pertaining to the specified system.

       Standard UUCP options:

       -X type, --debug type
	    Turn  on  particular debugging types.  The following types are recognized: abnormal, chat, handshake, uucp-proto, proto, port, config,
	    spooldir, execute, incoming, outgoing.  --debug option may appear multiple times.  A number may also be given, which will turn on that
	    many types from the foregoing list; for example, --debug 2 is equivalent to --debug abnormal,chat.

       -I file, --config
	    Set configuration file to use.

       -v, --version
	    Report version information and exit.

       --help
