tar

I have a 32GB .tar.gz archive and I'd like to know the size of the files if I unpack this compressed archive. I'd like to avoid unpacking the archive first and than use e.g. du.

Is it also possible to find out the size of the contained files without unpacking the compressed archive (on a Linux and/or MacOSX system)?

For another archive I know, that it also contains .tar.gz files. Is it also possible to calculate the size of the unpacked archives that are contained within an archive? (for example by setting a level to which the "unpacking" should be simulated?)

Way to avoid ssh connection timeout & freezing of terminal tab

When I connect via ssh terminal to certain servers, it timeouts and "freezes" the terminal (doesn't accept, doesn't disconnect, can't Ctrl-C to kill the ssh process or anything). This is in Ubuntu's Gnome-terminal, though it seems to be pausing the terminal input/output, and doesn't affect the operation… >>> More
