Weird behavior in bash and .bashrc

Question

I have added echo thisIsMyBash at the end of my .bashrc file. Now when I write create a new terminal with ctrl+alt+t , thisIsMyBash is written a the beginning. This is as expected.

Now when I type /bin/bash in my terminal thisIsMyBash is also displayed in my terminal.

But when I write /bin/bash -c "source ~/.bashrc" in my terminal, nothing is written. Why?

Also when I actually write /bin/bash -c "source ~/.bashrc" && exec /bin/bash -li thisIsMyBash also is displayed. Why that?

Any idea?

If you use the "-i" option of bash it will work as desired. This option make the shell interactive. Try this:

/bin/bash -i -c "source ~/.bashrc"
