On my Mackbook Air the default zsh is:
# use `zsh --version` to get this zsh 5.3 (x86_64-apple-darwin18.0)
I installed the newer version from Homebrew:
brew install zsh
Although, Homebrew installed the newer version (which is 5.8), when I checked it, it was still 5.3.
Then, I tried next steps.
First, find the location of zsh:
$ which zsh /usr/local/bin/zsh
Second, found out what's the shell I was using:
$ dscl . -read /Users/<username> UserShell UserShell: /bin/bash
. is short for localhost, the
<username> expands to my username on the Mac.
Third, I added the zsh's location to the shell file:
$ sudo vim /etc/shells # add `/usr/local/bin/zsh` at the bottom in it # use the next command line to change shell $ chsh -s /usr/local/bin/zsh # confirm whether it has changed $ dscl . -read /Users/<username> UserShell UserShell: /usr/local/bin/zsh
Yes. It has changed! Now I typed
zsh --version it showed the new one:
$ zsh --version zsh 5.8 (x86_64-apple-darwin18.7.0)
