Tar returns the same return values whether it succeeds or fails.
In perl, tar returns 0 whether it fails or succeeds. It especially is a
problem with a command such as
system('tar -zxf failure.tar.gz')
print $?
system('tar -zxf success.tar.gz')
print $?
So, if you use a bad tar.gz file for failure.tar.gz and a good tar file
for success.tar.gz above, you will note that either one returns the same
value of 0. Why?
