osx bash

from https://gimslab.tistory.com/m/entry/Install-bash-again-in-your-Mac-osx-why

It's a very outdated version of the Bash shell on Mac OSX. maybe like GNU bash, version 3.2

I needed full features of a recent version of bash. There are many exceptions in an old version of bash like this.

$ printf %d "'가'" -22 so just I did this to version up.

$ brew install bash and I can get the below version

$ bash --version GNU bash, 버전 5.1.4(1)-release (x86\_64-apple-darwin19.6.0) Copyright (C) 2020 Free Software Foundation, Inc. 라이선스 GPLv3+: GNU GPL version 3 or later <http://gnu.org/license/gpl.html>

This is free software; you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law. I have two versions of bash from now.

$ which -a bash /usr/local/bin/bash /bin/bash new one and the old one

add new bash to the whitelist shell file /etc/shells like below

% cat /etc/shells /bin/bash /bin/csh /bin/dash /bin/ksh /bin/sh /bin/tcsh /bin/zsh /usr/local/bin/bash set it as a default set

$ chsh -s /usr/local/bin/bash Good! I can get this same result with my other bash in Linux.
