Unix tar does not have a built-in (de)compression.
The advantage is that the newest (de)compression methods can be used without updating the tar binary.
The disadvantage is that you must get used to complex shell code.
Example:
The && is safer than the semicolon.
Is it possible to redirect the output from 'tar xvf' to another directory?
The taped tar image is extracting to my / dircetory - even though i'm running the command from /backups.
The contents list of the tape shows files created from /livebackups/...
Thanks

I would like to confirm my file.tar is been tar-ed correctly before I remove them. But I have very limited disc space to untar it.
Can I just do the listing instead of actual extract it? Can I say confirm folder integrity if the listing is sucessful without problem?

chroot
chroot(1M) System Administration Commands chroot(1M)NAME
chroot - change root directory for a command
SYNOPSIS
/usr/sbin/chroot newroot command
DESCRIPTION
The chroot utility causes command to be executed relative to newroot. The meaning of any initial slashes (/) in the path names is changed
to newroot for command and any of its child processes. Upon execution, the initial working directory is newroot.
Notice that redirecting the output of command to a file,
chroot newroot command >x
will create the file x relative to the original root of command, not the new one.
The new root path name is always relative to the current root. Even if a chroot is currently in effect, the newroot argument is relative to
the current root of the running process.
This command can be run only by the super-user.
RETURN VALUES
The exit status of chroot is the return value of command.
EXAMPLES
Example 1 Using the chroot Utility
The chroot utility provides an easy way to extract tar files (see tar(1)) written with absolute filenames to a different location. It is
necessary to copy the shared libraries used by tar (see ldd(1)) to the newroot filesystem.
example# mkdir /tmp/lib; cd /lib
example# cp ld.so.1 libc.so.1 libcmd.so.1 libdl.so.1
libsec.so.1 /tmp/lib
example# cp /usr/bin/tar /tmp
example# dd if=/dev/rmt/0 | chroot /tmp tar xvf -

Exercise extreme caution when referencing device files in the new root file system.
References by routines such as ttyname(3C) to stdin, stdout, and stderr will find that the device associated with the file descriptor is
unknown after chroot is run.
