tar

In Unix, how can I uncompress *.Z or *.tar.Z files?

If you are on a Unix system, to uncompress *.Z or *.tar.Z files, at the shell prompt, enter:

 uncompress *.Z

Use the ls command to check the resulting files. If uncompress creates a .tar file, you must extract the files by entering:

 tar -xvf *.tar

Alternatively, to do this in one step and avoid creating the intermediate *.tar file, enter:

 zcat *.Z | tar -xvf -
