Extract a single file from a tar file to another directory
Hi,

I need to extract a single file from a tar file to another directory.

So far I have this:

This one extract a single file to same directory:
Code:
tar -xvf filename.tar ./file.txt

I tried this but its not working

Code:
tar -xvf filename.tar /home/dir ./file.txt

or this:

Code:
tar -xvf filename.tar -C /home/dir ./file.txt
