grep return more than one line
Hi,

I have a lot of log files which contain lines in the format of (date info) or (info), and when I use grep to search for "date" I was able to get the (date info) line, but some info lines are a separate line after the (date info) line... for example like:

(date info info info)
(date info info)
(info info)
(date info) (or end of file)
I want grep to return the date info line and any further info lines containing the date parameter i enter.

any help would be greatly appreciated, thanks.

avbdiagnose

avbdiagnose(1)						    BSD General Commands Manual 					    avbdiagnose(1)

NAME

     avbdiagnose -- diagnostic tool for AVB.

SYNOPSIS

     avbdiagnose

DESCRIPTION

     The avbdiagnose tool is used to capture a snapshot of the current AVB system state and help diagnose common issues with AVB.

     avbdiagnose looks for the system to determine that it actually has AVB capable interfaces and that at least one of these has been enabled.

     avbdiagnose will produce a number of warnings which may not be errors depending on the setup of the system.  Things such as missing local or
     remote attributes for MSRP will be flagged as a warning but is not an error if the Mac is not sourcing or sinking streams as appropriate for
     the warning.

     avbdiagnose will flag potential errors and warnings and suggest filing a radar report at http://bugreporter.apple.com.  Please attach the
     generated file at /tmp/avbdiagnose-<date>.bz2 to the bug report. An error or warning report may be the result of a network device. Please use
     your best judgement before filing the bug report.

     The following options are available:

     --no-enumeration
	 Disable the reading of the AVDECC AEM from the device and archiving it in the result.

     --no-coreaudio
	 Disable dumping of the state of the AVB audio driver device tree.

     --acmp-state
	 Enabled reading of and dumping the ACMP state of the entities.

     --stream-info
	 Enable sending of the AVDECC AECP AEM GET_STREAM_INFO command to each of the possible stream sources and sinks and including in the info
	 dump.

     --stream-counters
	 Enable sending of the AVDECC AECP AEM GET_COUNTER command to each of the possible stream sources and sinks and including in the info
	 dump.

     --no-info-tree
	 Disable dumping of the state of the AVB info tree.

     --no-timesync
	 Disable dumping of the state of the Time Sync info tree.

FILES

     /tmp/avbdiagnose-<date>.bz2		   output The information gathered by avbdiagnose including the command line output, an ioreg dump
						   and the current system.log and kernel.log files.
