A block starts with the word RCS and ends with the pattern ======
I used the following command

awk '/.java,v/,/====/'

and it extracted all the blocks of data for java files i.e. starting and ending with the pattern ======. This is good.

However, I also want to extract some more information from each block and store that also.
For example, I want to count how many revisions are there in each block, how many distinct authors worked on that file, how many lines added/deleted in total for each file, etc.

Can anyone help me out how to extract this information from each block and store that in a tab separated file? Even if I do not get the values of the individual revisions/author names, etc. it is ok. I just want to get the count for revisions (total or the sum of lines added, etc).

Any starting help on even how to work with these individual blocks will be useful. Do I have to use some for loop to work with each block?

Thanks,
Sandeep

cvsconnect

CVSCONNECT(1)															     CVSCONNECT(1)

NAME

       cvsconnect - CVS connection minimizer

SYNOPSIS

       cvsconnect cvsroot [command-to-run ...]

DESCRIPTION

       CVSconnect enables you to do multiple CVS operations on single network connection.  CVSconnect sets up special environment using
       $CVSRSH/$CVSROOT for the command line CVS client.  In the environment, the command line CVS client reuses a network connection.

       CVSconnect is especially designed to use with CVSsuck.  And CVSconnect (or similar) will be integrated to a future version of CVSsuck.
       However, it is planned that CVSsuck directly connects to a cvs server without cvs command.

EXAMPLES

	cvsconnect $HOME/.cvsroot

BUGS

       o   The global option -z for compression cannot be used.  If you use SSH via ext method, you can use compression by SSH instead.

       o   CVS client must be run at a time.  Running two or more clients at a same time will make a trouble.  (will be fixed in future release.)

       o   Some static variables in a CVS server may confuse you.  It's a CVS bug.  Report it to CVS developer :-).

       o   Command line CVS client must request `Root' first.  Don't mind.  There is no implementation which violates this assumption, however I
	   know.  At least, CVS-1.10 and CVS-1.11 should work.

NOTES

       o   When CVS command is failed, CVSconnect automatically re-run the command with reconnected connection when CVS command is failed.
	   Especially the failure is caused by a long running CVS-1.10 server.	Since CVS-1.10 doesn't close some file descriptors, a long running
	   CVS server will exceed a limit of file descriptors.

       o   /bin/sh should be POSIX sh because this script uses ${parameter#pattern}, etc.  If your /bin/sh is ancient Bourne shell, use ksh or
	   bash.
