38 Verifying the Installation
The arguments follow the
cvf
options in the command line. Their values
depend on the operating system; suggested values are given in “System-
Specific Arguments” on page 39 . The arguments are as follows:
Note Make sure you prefix the file name with ‘
.
’ when you back it up
to tape. If you do not, the restore operation in step 3 will
overwrite the original copy on disk.
5 Read the file back from tape:
% cd /tmp
% tar xvf <archive name>
The ‘
x
’ option to
tar
here means “extract from the archive”.
Use the same value for the
<archive name
> argument as in step 2.
6 Compare the original with this retrieved file:
% cmp <original file> /tmp/<retrieved file>
This step compares the retrieved file and the original file byte by byte. If
they are the same, there should be no output, and this verifies that the
installation is correct. The arguments are as follows:
Example:
