Moving bash files to relevant directory


Hi
My home directory contains following bash related files:
Code:
.bash_aliases          .bash_functions  .bash_logout   .bashrc
.bash_eternal_history  .bash_history    .bash_profile  .bash_variables
I want to move all these files in a directory (~/.bash). I know how to move all these files and make relevant changes in .bashrc file. When I login, my bash loads ~/.bash_profile file and by making following changes in the contents of ~/.bash_profile I can move ~/.bashrc and other files to ~/.bash:
Code:
# ~/.bash_profile
#

[[ -f ~/.bash/.bashrc ]] && . ~/.bash/.bashrc
But I don't know how can I move ~/.bash_profile itself, as it is the first file which bash looks for after login. So where should I make changes so that bash looks in ~/.bash directory for .bash_profile?
Thanks

You can't. BASH is hardcoded to look for .bash_profile in the root of your home directory.

From the bash-5.0 source code (all indentation preserved):

Code:
      /* Execute /etc/profile and one of the personal login shell
	 initialization files. */
      if (no_profile == 0)
	{
	  maybe_execute_file (SYS_PROFILE, 1);

	  if (act_like_sh)	/* sh */
	    maybe_execute_file ("~/.profile", 1);
	  else if ((maybe_execute_file ("~/.bash_profile", 1) == 0) &&
		   (maybe_execute_file ("~/.bash_login", 1) == 0))	/* bash */
	    maybe_execute_file ("~/.profile", 1);
	}

yes, those files should be there, the location (and name) is hardcoded. Even .bashrc has a default name and location (which can be modified), but easier to keep it as is.

But nothing prevents you from
Code:
mkdir ~/.bash
for f in aliases functions variables
do mv ~/.bash_$f ~/.bash/$f
done
sed -Ei 's,\.bash_(aliases|functions|variables),.bash/\1,g' ~/.bashrc

Thanks a lot.
I was thinking that it can be done by /etc/profile.

I have moved all ~/.bash* files except ~/.bash_profile and ~/.bashrc.
Initially, I had also moved ~/.bashrc to ~/.bash.d/.bashrc and adjust ~/.bash_profile as follows:
Code:
# ~/.bash_profile
#

[[ -f ~/.bash.d/.bashrc ]] && . ~/.bash.d/.bashrc
But bash did not recognize ~/.bash.d/.bashrc. So it looks like that ~/.bashrc is also hardcoded!

you need to read the man page of bash and you will see how and when will these files be processed (look for invocation).

Why did you not include this thought in your original question?
It's possible, but fragile:
- does it really apply to all users?
- what if any of the files bash wants to source automagically is present?
