Linux – How to have Linux ls command show second in time stamp

You can use PipeViewer for this

pv firstfile | cmp -l secondfile > output

It did not work because you changed the timestamp of the archive, not of the files it contains. If you run stat on the tar.gz file you will find that the time was changed correctly. touch cannot access the files stored within the archive until you extract them so they were left unchanged.

In any case, this should not be a problem, just untar the archive, then change the timestamp of the files:

mkdir foo
mv openssl-1.0.1e.tar.gz foo/
cd foo/
tar xvvzf openssl-1.0.1e.tar.gz
find . -exec touch -am '{}' \;
