How to change the `sh` command to run scripts in bash 4 I have installed bash 4 with Homebrew and bash --version shows me the version 4.

If I have following test script:

#!/usr/local/bin/bash
# test-version.sh
echo $BASH_VERSION


And I make it executable chmod +x configurer.sh and run it ./test-version.sh I also get the version 4.

But if I run it with the sh command sh test-version.sh I get the version 3.

I have put the new shell into /etc/shells:

sudo bash -c 'echo /usr/local/bin/bash &gt;&gt; /etc/shells'


And changed to the new shell:

 chsh -s /usr/local/bin/bash


I also changed the path in iTerm Settings > Profiles > Command to /usr/local/bin/bash.

Thanks!

EDIT: I've come to realize that it's good to leave sh alone. When wanting to run scripts with Bash 4 just don't use sh.
I used homebrew to install BASH4 and I use the shebang #!/bin/bash every time. This works for me with both sh and ./ styles of running.
