TAR Help.....

[Rajkumar_3]

Hai all,

I have 3 directories /home/classes ,home/lib, /home/config..

I need to take a backup of these three directories using "TAR".But while extracting i will declare an environment variable some thing like "TEST_HOME=/../.. . In this i will specify the path to extract the 3 directories...

How can we take perticular those 3 directories and how can we extract those directories in different paths...??

Any help please...

Raj

You can't tell tar to use an arbitrarily defined environment variable.
Try this:
cd /home; tar cv classes lib config (... or just *)
Then , when you want to extract, you can do this:
cd $TEST_HOME; tar xv
This will extact all the directories tarred into $TEST_HOME.
If you want a separate path for each directory, use a temp directory like so:
mkdir -p /tmp/extracts; cd /tmp/extracts; tar xv ; mv ; mv ; ...

HTH

Uh-oh.. Apologies to anyone who wanted to post a "I know the answer, but I wont post it till you improve your points allocation record"

Hi,

Use tar's -T (or --files-from F)option to get names to extract or create from file F

Hope this helps. Regards.

Hi Raj,

If you create the tar using absolute pathnames for the files you backup, you will not be able to restore them to an alternate location. You will need to use relative pathnames for your backup.

HPUX 11.0's tar does not have either T or F option.

Deepak has the answer for you:
cd /home
tar cvf tarfilename classes lib config
cd $TEST_HOME
tar xvf tarfilename

Very important: be sure cd $TEST_HOME is successful before un-tarring. If not (for exampe the directory doesn't exist), you will be extracting into whatever directory you were in before trying to cd. After the cd command, check that $? = 0.

Hi,

I forgotten to mention that for the -T option, you will need to install GNU tar to have this option.

As already pointed out, the default tar that comes with HP-UX does not have it.

Hope this helps. Regards.

Hi

If you backup using ./home/classes ,./home/lib, ./home/config
you will be able to restore anywhere you want.
