I’m using GNU tar version 1.14 on Linux 2.6.9-22.ELsmp

I’m looking into using command: tar --directory=/home/brendan/tarFileTest -xzvf Archive.tgz

Is the whole process (unzip and untar) done in memory? Or in a step-by-step process - unzip to directory, then untar in directory?

Where can I find the error codes when the above command is executed when there is none or not enough free space in the directory the untar’d and unzip’d files are to be extracted to?

Is there some switch or other way to find out from the Archive.tgz file how much disk space would be required to hold the extracted files before executing the tar xzf command?
