Knowing the extracted size of compressed tarball without extracting

kushalkoolwal · 11-04-2005, 02:31 PM

hi,

I have an a compressed tar ball called data.tar.bz2. Can I know the space(inMB) that will be taken after I extract the compressed tar ball without extracting it in the first place?

In short, I don;t want to actually extract the tar ball but somehow know how much space will it take after extraction?

Thanks

bzip2 -dc $tarbz2 | wc -c
or
bunzip2 -c $tarbz2 | wc -c

same with gzip / gunzip
