CentOS - Jan 2011 - tar-ing subdirectories separately

I want to backup a directory using tar, but want separate tarballs for each
subdirectory. For example:
# ls dir1
subdir1 subdir2 subdir3

Will it possible to do it using only tar command? Or will I need another
separate piece of logic/control? I thought of writing a shell script with
three tar commands for each subdirectory, but that's not elegant way of
doing it. Also, it may not scale as number of subdirectories change. Any
other solutions or tips for doing this will be really helpful.

Thank you

You can try something like :
find /dir1 -type d -print -maxdepth 0 | while read DIR ; do tar cfv
$DIR.tar $DIR/; done

not tested, just off the top of my head and it's late, so if it breaks,
you can keep and be happy with all the pieces ;)

No, tar only generates a single output stream.

What's not elegant about a script that does exactly what you want?

Decide how you want to specify the list (in the script, in something the script 
can read, or a wildcard name expansion) and use a 'for' shell loop with
the list
that also expands the name into the output filename.

Use find(1) for such cases.

$ find <dir> -mindepth 1 -maxdepth 1 -type d -exec tar cz {} -f {}.tgz \;
