Why is that?

Answer 1

There is probably another answer with this information in it already, but I am just going to answer and not look for it.

.bash_profile vs. .bashrc

So, .bash_profile is executed when Bash is invoked as an interactive login shell. .bashrc is executed when bash is invoked as a non-login shell.

You can either add your prompt stuff to ~/.bash_profile or, source ~/.bash_profile from ~/.bashrc <- this is pretty common.

Example of sourcing ~/.bashrc from ~/.bash_profile

# ~/.bash_profile

# some lines of stuff

if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

Further troubleshooting

The file /etc/profile is also sourced at some point but I believe it is before hand. I have seen some weird things happen though we people modifying this file.

If the above doesn't work could you update your question with the contents of your ~/.bash* files?
