@agent.kgb:

You don't need GNU-tar, it is possible with a standard tar too by untarring to stdout:

Code:
 tar xf - /path/to/file.tar | grep "<what-you-search>"

@sanjaydubey2006:

As far as i can see agent.kgb (and the other people in the second thread you opened) have given you very sound advice. If you still are not able to do what you want to do there are two possible reasons:

Either you have not described your problem well. Instead of having asked for what you really want to do you asked for something you thought you might need to do what you want to do. Analysing a problem correctly at least to the point where one is able to concisely state what the problem is is trait you absolutely will need as a systems administrator - especially a UNIX systems administrator. Think about that.

Or - and this would pose an even greater problem - you absolutely have no idea how what you want to do is done and expect us to give you a turn-key solution. Now, i hate to break the news to you, but we cannot teach you the basics of script programming in specifc, programming in general and how a UNIX system works over the internet in a forum. This is simply not the right place for such an endeavour and i suggest you get a good book about this, take some classes or whatever means of getting tought about the topic is available for you. If this will leave specific questions you will be welcome to ask them here and get answers.

Second: we want to help, but we cannot do your work for you. We all have jobs of our own and cannot do yours. We can help you to help yourself but this is "UNIX for beginners", not "have your script written for you by willing volunteers".

There i suggest you rethink your attitude and/or the correlation of job requirements in contrast to your expertise and start over.

I hope this helps.

bf_tar

BF_TAR(1)						    Bogofilter Reference Manual 						 BF_TAR(1)

NAME

       bf_tar - shell script to write a tar file of a bogofilter directory to stdout

SYNOPSIS

       bf_tar [-r] [-R] bogofilter_directory

DESCRIPTION

       bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see
       EXAMPLES below).

OPTIONS

       The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log
       files.

       The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive
       is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files.

EXIT STATUS

       The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.

EXAMPLES

       o   bf_tar ~/.bogofilter > outfile.tar

	   Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar.

       o   bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz

	   Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz.

       o   bf_tar `pwd`/mydirectory > outfile.tar

	   Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path.

NOTES

       This script is meant for use with Berkeley DB based bogofilter versions.

       This script requires a SUSv2 compliant pax utility.

       This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so
       that /usr/xpg4/bin/sh can be used.
