Topaz: .bashrc Not Being Sourced

Problem

Shell startup file .bashrc not being sourced specially on Topaz

This is specially a CentOS/Red Hat 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, that is 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. For example:

• 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

$ cat .bashrc 
# .bashrc

if [ -f /etc/bashrc ]; then
	. /etc/bashrc

# Uncomment the following line if you don't like systemctl's auto-paging feature:

# User specific aliases and functions

$ cat .bash_profile 
# .bash_profile

if [ -f ~/.bashrc ]; then

export PATH

root@topaz-1:/etc/skel>cat .bashrc 
# .bashrc

Solution

Thus to fix this, 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

  Listing 1: Additional lines for the .bashrc file

  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

  Listing 2: Additional lines for the .bash_profile file

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