hi let's think about the way we access the file which contained in a tar file may we can untar the whole thing and we find the file we want to access or we can use the t option with tar to list all the files in the tar and then untar the only one file we want to access. but with the help of the tarfs,we can mount a tar file to some dir and access it easily and quickly.it's like the tarfs in mc. just mount -t tarfs tarfile.tar /dir/to/mnt -o loop then access the files easily. it was writen by Kazuto Miyoshi (kaz@earth.email.ne.jp) Hirokazu Takahashi (h-takaha@mub.biglobe.ne.jp) for linux 2.4.0 and i make it work for linux 2.6.0. now a patch for linux 2.6.10-rc1-mm3 the patch is to big to send it as plain text, so i can only send it as an attachment thanks -- Yours andyliu
