Script to find tar archives, read tar file contents, output content to an index file.

Just doing some tests, making directories into tar files:

find . -type d -links 2 -exec tar cvf {}.tar {} \;

Works fine.

I have been trying to do:

$ find . -type f -name \*.tar -execdir tar tvf {} > {}.lst \;

The result:

tar: Error is not recoverable: exiting now
tar: ./Outbox.tar: Cannot open: No such file or directory

Among other things (-iname, choosing between -execdir and using fixed or user-supplied full paths with loops, extension checking, getting rid of error messages) you need proper quoting as in

Code:

find /some/path/ -type f -iname \*.tar.\* 2>/dev/null|egrep -ie "\.(bz|bz2|gz|xz|z)$" 2>/dev/null|while read FILE; do tar -tf "${FILE}" > "${FILE}.ndx" 2>/dev/null; done

I'm mostly a hardware guy, so please go easy on me.

Yes, I still have much to learn.

And, thanks!

NP, that's what we're here for. Here's some help if you need it BTW:

Code:

Thank you for your help. With the nice kick start above, I was able to create some of my own scripts that did the job just nice.
