How did I overwrite a file to in "tar" file.
For example I have file "backup.tar" in my home directory, which contains two file "x.sh" and "y.sh"
I made some changes to one of the file "x.sh" and want to update the " backup.tar"
I use tar -uvf, but this appends at the end of the tar file, but what I want is replace the file.
The only way, I know of right now is, delete the file by issuing the following command
tar --delete --file=backup.tar x.sh
and then adding the file again using
tar -uvf backup.tar x.sh
Is there a better way of doing this, on a single command.
Thanks in Advance
