Where can I put commands that I want to run for all interactive, non-login shells?

Normally, in bash, the answer would be ~/.bashrc or /etc/bash.bashrc. But unfortunately Ubuntu is sourcing these files from ~/.profile and /etc/profile respectively. So, where should I put such commands on Ubuntu?

It appears there is no standard place for such commands on Ubuntu (without modifying behaviour that may be considered standard on Ubuntu). Here is a work-around that I came up with:

Add this to the beginning of /etc/profile:

IS_LOGIN_SHELL=1

Then, in /etc/bash.bashrc or ~/.bashrc test for this variable:

if [ -n "${IS_LOGIN_SHELL-}" ]; then

   # Put your commands here

fi

Hopefully the variable name won't collide with anything else and this doesn't change what other parts of Ubuntu may rely on.
