bashrc not found on MacOS Monterey version 12.0

Question

I am using MacOS Monterey version 12.0

I checked in root directory, I don't have .bashrc and .bashprofile, but my system is using .zshrc and .zprofile

I am getting error that

./bin/temp.sh: line 3: /Users/xyz/.bashrc: No such file or directory

Code of temp.sh file at line 3 :

#!/usr/bin/env bash

source ~/.bashrc. # This line is causing error

Temporarily, I replaced this line with below and it is working

#!/usr/bin/env zsh

source ~/.zshrc. # This is working fine !!

From searching over few answers and posts, I got to know that Mac systems are transitioning to zsh from bash, because zsh is improved version of bash

Can anyone tell me proper solution of routing .bashrc or .bashprofile commands to fetch internally .zshrc or .zprofile ?

what will be best solution so that same script file can run on both systems having zsh and bash shells?

Answer 1

If you want your script to use zsh, you will need to replace the first line which calls your shell, to make it call zsh instead of bash:

#!/usr/bin/env zsh

And then make sure your script isn't using anything specific to bash, or adapt the script to replace tit's "bashisms" with the zsh-specific equivalents.

Alternatively, you could also just create the file you need to source with the content you want. The real question is why is your script trying to source .bashrc? Which variables/functions/whatever does your script want to initialize from there?
