![]() ![]() But the change is not effected in the current window, until you do something like exec su - $USER as suggested by or until you close and open a shell window. read /Users/$USER/ UserShell immediately afterwards, and you will see UserShell: /bin/zsh. What chsh -s /bin/zsh does is change this UserShell property to set it to zsh - you can check this by doing dscl. Let’s install zsh using brew and make iTerm2 use it. By default, macOs ships with zsh located in/bin/zsh. If you want to just make your regular Bash Terminal powerful, take a look at my previous blog: Jazz Up Your Bash Terminal. This information will passed to your terminal app when you open a shell window. Zsh is a shell designed for interactive use, although it is also a powerful scripting language. In this blog I’ll cover installing ITerm2, ZSH shell, oh my ZSH, Themes, ITerm2 color schemes, oh my ZSH plugins and enable ligature support to help create a beautiful and powerful Terminal. For example, if, say, bash was your default and you open a new bash shell window from terminal then $ export SHELL="/bin/zsh" echo "$SHELL" would show /bin/zsh but no actual change will occur because if you open a new shell window from terminal and do $ echo $0 then you would see -bash ( $0 contains the name and path of the command that started the shell window, in this case bash, and the - next to it indicates that it is a login shell).Īs pointed out the actual default login shell for the user is controlled by the UserShell property in the user's record in the system's internal database - this can be queried and updated using the command line utility dscl. ![]() brew install zsh Step 4: Install Oh My Zsh Oh My Zsh is an open source, community-driven framework for managing your zsh configuration. You can enrich ZSH by using the Oh My ZSH framework which provides some. I think the SHELL environment variable reflects but does not control the actual default login shell for the user. Zsh is a shell designed for interactive use, although it is also a powerful scripting language. Since macOS Catalina (10.15.2) the default shell is now ZSH instead of Bash. I had a similar problem in doing the opposite on my system (OS X 10.10.1): making bash the default login shell again after I had installed oh-my-zsh, which made zsh the default, and then upgrading bash from 3.2.53 to 4.3.30 using Homebrew (why is Apple shipping Yosemite with an old bash version?). Look here for the excellent explanation and solution posted by [in relation to a bash upgrade problem. ![]()
