Problem

Shell startup file .bashrc not being sourced specially on Topaz

This is specially a Centos / RedHat Specific issue as the .bashrc is sourced by the user shell startup

  • Magnus / Galaxy / Zeus are essentially based on SuSE SLES12 where the default user profile automatically sources this
  • Whereas Topaz ie Centos 7 does not


To understand the problem 

Centos Specific basically in short

  • ".bash_profile" is sourced for login shell
  • ".bashrc" is sourced for interactive non-login shells.

The dummy default Centos Specific home area, they have a dummy file for .bash_profile and .bashrc ie

  • Notice in the dummy default .bashprofile they execute ~/.bashrc
  • Notice in the dummy default .bashrc they source /etc/bashrc
  • So they have to be explicitly sourced in the user version's of .bashprofile and .bashrc which is not needed in SUSE SLES12

Solution

Thus to fix this, I would do the following assuming you have a default SLES based home area

For ".bashrc" in your home area (ie /home/{username}/.bashrc

  • Add the following lines
if [ -f /etc/redhat-release ]; then
    if [ -f /etc/bashrc ]; then
	    . /etc/bashrc
    fi
fi


Similarly for ".bash_profile" in your home area (ie /home/{username}/.bash_profile

  • Add the following lines
if [ -f /etc/redhat-release ]; then
    if [ -f ~/.bashrc ]; then
	    . ~/.bashrc
    fi
fi
