Ubuntu – .bashrc configuration

.bash_profile vs. .bashrc

Ref: https://apple.stackexchange.com/questions/51036/what-is-the-difference-between-bash-profile-and-bashrc

• .bash_profile is executed for login shells
  • When you login (type username and password) via console, either sitting at the machine, or remotely via ssh, .bash_profile is executed to configure your shell before the initial command prompt
• .bashrc is executed for interactive non-login shells
  • If already logged in, just open a new terminal window (xterm) then .bashrc is executed before the window command prompt.
  • .bashrc is also run when you start a new bash instance by typing /bin/bash in a terminal.
• On OS X, Terminal by default runs a login shell every time, so this is a little different to most other systems, but you can configure that in the preferences

Call .bashrc from .bash_profile

Add the following to your .bash_profile, you can then move everything into your .bashrc file so as to consolidate everything into one place instead of two:

if [ -f $HOME/.bashrc ]; then
    source $HOME/.bashrc
fi
