To install the zsh shell on a FreeBSD system, you will need to do the following:
# pkg update
zsh package using the pkg package manager:# pkg install zsh
This will install the zsh shell on your FreeBSD system.
To make zsh the default shell for a user, you can use the chsh command.
For example, to make zsh the default shell for the foo user, you can run the following command:
# chsh -s /usr/local/bin/zsh foo
This will change the default shell for the foo user to zsh.
To start the zsh shell, you can simply run the zsh command on the command line.
For more information about using and configuring the zsh shell on a FreeBSD system, you can refer to the zsh documentation and the zsh man page by running man zsh on the command line.
