Tar up only 3 specific files in command line with linux

Question

Is it possible with one command to tar up 3 files into one tar archive?

For example, tar up:

public_html.tar.gz

dbapp.sql

dbwp.sql

into a tar file called bak.tar.gz

Solution

tar acf bak.tar.gz public_html.tar.gz dbapp.sql dbwp.sql

Or if you dont have a option

tar zcf bak.tar.gz public_html.tar.gz dbapp.sql dbwp.sql
