Restoring a single file from a group of files using tar
Hello
I take a backup using the following command on Solaris 9

tar cvf /dev/rmt/0n data

the data volume contains a number of files say a, b, c , d ... etc

Now I want to restore only one file (eg b) from the data volume.
When I issue the command
tar xvf /dev/rmt/0n data/b
I don't get the file restored.
How can I do that please?

First look for your file if it exist:

Code:
tar --list -f archive.tar | grep foobar.txt

then extract:

Code:
tar -x -f archive.tar my/path/to/foobar.txt

if you have a catalogue with the name "On data" you might need to put "" around your whole file name so tar recognizes the file name.
