From the bash man page:
When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.
When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc
Every new terminal window/tab that you open will load .bashrc
On a brand new user account, none of these files will exist, they can be created with any suitable text editor that is capable of creating plain text files with unix style (LF) line endings. Save them into your home folder (~/)
Adding aliases to this file has exactly the same affect as putting the aliases in .bashrc the advantage of .bash_aliases is that having all your aliases in one file makes it easier to re-load them when you make changes.
Add the following to .bashrc so that .bash_aliases is always loaded:
if [ -f ~/.bash_aliases ]; then
The command . ~/.bash_aliases will source (load) ~/.bash_aliases in the context of the currently running shell.
bash prompt - PS1
bashrc_dispatch - use symlinks to reorganise .bashrc, .bash_profile and .profile
.inputrc - Startup files (Set Key bindings and Tab completion)
alias - Create an alias
