File Reading for a certain string and echo the line before

Hi Guys,

I have a big file like this. It has cache group line ( the bold lines ) and then followed by 10 status lines showing either Compelte or Failed. This pattern repeats several time. We can assume all the status lines have either Complete or Failed status for that Cache Group line.

I need to find a way to display just the failed cache group lines ( echo of that line ). Here I just want to see one line "call ttcacheautorefreshstatsget('CGOWNER','CG_CLIENT_PLAN');"

Have been struggling for a day but not finding a good solution. Can something like this be achieved using shell scripting or do I have to use perl ?

Hope I didn't confuse in explaining what I want.

Code:

call ttcacheautorefreshstatsget('CGOWNER','CG_CLIENT_NOTE');

pk-debuginfo-install

PK-DEBUGINFO-INSTA(1)						  [FIXME: manual]					     PK-DEBUGINFO-INSTA(1)

NAME

       pk-debuginfo-install - Debugging Packages Installer

SYNOPSIS

       pk-debuginfo-install [--help] [--verbose] [--simulate] [--no-depends]

DESCRIPTION

       This manual page documents briefly the pk-debuginfo-install command.

       pk-debuginfo-install is the command line client for installing debuginfo packages.

WHY DO I NEED DEBUGINFO PACKAGES
?
       When a program crashes, it's often useful to send the developer a backtrace which contains symbol names and variable contents, rather than
       memory addresses. To make this possible, extra packages called debug packages can be installed.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
       below.

       --help
	   Show summary of options.

       --noninteractive
	   Do not be interactive and skip the confirmation before the packages are installed.

       --verbose
	   Show extra debugging information.

       --simulate
	   Don't actually install any packages, only simulate what would be installed.

       --no-depends
	   Do not scan for, or install dependencies of the core packages.

       --quiet
	   Do not display information or progress to the terminal.

RETURN VALUES

       0
	   Success, at least one package was installed

       1
	   Failed with miscellaneous internal error.

       3
	   Failed to get software sources list.

       4
	   Failed to enable software sources.

       5
	   Failed as nothing to do.

       6
	   Failed to find dependent packages.

       7
	   Failed to install.

       8
	   Failed to disable software sources.
