well the simple way to create a tar file from the current directory of stuff you're currently sitting in...

cd /mysourcedir
tar cvf .tar .

where is the name of the tar file you wish to create, or the name of the tape drive you're trying to hit (e.g. /dev/rmt/0m).

so
cd /mysourcedir
tar cvf mysourcedir.tar .
or simply
tar cvf mysourcedir.tar /mysourcedir

would create a tar file of the contents of /mysourcedir. The first example buries the name of the directory as "." and the second buries the name of the directory as "/mysourcedir". This makes a difference when you extract the data later on.

To extract the data:

cd /mydestdir
tar xvf .tar .

would put the contents of .tar in the current directory (/mydestdir).

If you used the second method (mentioned above) to create the tar file with the absolutepath /mysourcedir embedded in the tar file, then you don't have much choice but to extract the data into /mysourcedir as well.

tar xvf .tar

would create the directory "/mysourcedir", if it doesn't exist, and put the files from the tar file in the /mysourcedir directory.

There's more, but that's the main two commands for tar.

Of course,

"man tar" for the rest.

Essentially the same way you use tar on any other UNIX box. Man tar will tell you all you need to know.

Hi Manuales:

# tar -cvf /tmp/archive /home

..would (c)reate a (f)ile named "/tmp/archive" for the contents of the '/home' directory and (v)erbosely record to your terminal the files archived.

# tar -xvf /tmp/archive

...would e(x)tract the archive (back into '/home' since we used absolute paths (not always a good thing!)

# tar -tvf /tmp/archive

...would merely list the contents of the archive.

With 'tar' archives (whether to a tape or to a file) it is ofter better to use relative paths. Thus in our first example:

# cd /home && tar -cvf /tmp/archive .

...would allow restoration later in a directory of our choice without a great deal of bother.

See the manpages for 'tar' and its cousin 'pax'.

Regards!

Hi Manuales..
the use of tar command is same in all the flavour of unix...

tar is basically used for backup purpose.means you can take a backup of ur file by using tar..

# tar cvf < name of destination>

name of destination= /dev/rmt/0mn (device name of ur tape drive).

# tar cvf /dev/rmt/0mn /home
it will take a backup of ur home directory...

and you can view

# tar tvf /dev/rmt/0mn

and you can extract the backup

# tar xvf /dev/rmt/0mn

you can also make a archive file by using tar

tar cvf home.tar /home

i think this will solve youe doubt. see man page also..

regards
karan
