[options] [tarfile] [files]
The tar command copies a file or files to or from

telnet command prompt and replace tarfile with the name
you want to call your archived file, and replace directory
with the name of the directory that contains the files you
want to tar.
To extract the files from a tar format archive, simply type
"tar xvf tarfile at a telnet command prompt and replace
tarfile with the name of the archived file you are
extracting.
For example, you could type tar cvf pages.tar htdocs" at a telnet
command prompt to archive the files in the htdocs
directory to a tar format file called pages.tar.
To view the contents of the pages.tar tarfile without extracting
them, type "tar tvf pages.tar". This will display all files that
are included in the tar archive.
You could also type "tar xvf pages.tar" at a telnet
command prompt to extract into the current directory the
files in the archive pages.tar.

[files]
The compress command shrinks a file or files into
compressed versions to save space on your Virtual Server.
This command is good for you to use on your log files
when they get very large. Simply type "compress

filename(s) with the name of your files you want to
compress.
For example, type "compress access_log agent_log" at a
telnet command prompt to compress the access_log and
agent_log files. The compressed files will then be
access_log.Z and agent_log.Z.
