Sourcing from a different bashrc

Question

My original .bashrc script is currently used to run model runs. Now I need to manipulate it to compile a completely new model.

My question is, if I save my original .bashrc, as something such as .bwwbashrc, do I need to manipulate the file in some way so it is able to be read or recognized as the .bashrc when I source it within my scripts?

original sourcing

source /home/tsee/.bashrc

What I think the new sourcing would be. (after creating .bwwbashrc)

source /home/tsee/.bwwbashrc

Just not sure if I need to save it with a certain extension or edit the executable in some sort of way.

Answer 1

Nope, you can name it whatever you want. Executable bit isn't required either.

If you aren't aware of it, the bash --login option might be of interest to you.

Answer 2

To complement Matt's correct answer, I'd also point out that you can start a new Bash shell that sources your alternative file instead of .bashrc at start-up.

bash --rcfile .bwwbashrc

From the bash man page:

--rcfile file

Execute commands from file instead of the standard personal initialization file ~/.bashrc if the shell is interactive (see INVOCATION below).

If you want to replace your current shell (with commands and settings from .bashrc ), you can run

exec bash --rcfile .bwwbashrc
