So Im learning to develop in Rails, and have discovered the power of zsh. However, for some of my other tasks, I wish to use normal Bash. Although they are the same, I just feel comfortable with the lay out of bash in some situations. How do I switch back and forth, or turn zsh on and off? Thanks!
You should be able just to type bash
into the terminal to switch to bash, and then type zsh
to switch to zsh. Works for me at least.
you can try chsh -s /bin/bash
to set the bash as the default,
or chsh -s /bin/zsh
to set the zsh as the default.
Terminal will need a restart to take effect.
you can just type bash
or if you always want to use bash:
on "iTerm2"
bash
Test by closing iTerm and open it again
I switch between zsh and bash somewhat frequently. For a while, I used to have to source my bash_profile every switch. Then I found out you can (typically) do
exec bash --login
or just
exec bash -l
zsh has a builtin command emulate
which can emulate different shells by setting the appropriate options, although csh will never be fully emulated.
emulate bash
perform commands
emulate -R zsh
The -R flag restores all the options to their default values for that shell.
See: zsh manual
In Mac OS Catalina default interactive shell is zsh. To change shell to zsh from bash:
chsh -s /bin/zsh
Then you need to enter your Mac password. Quit the terminal and reopen it. To check whether it's changed successfully to ssh, issue the following command.
echo $SHELL
If the result is /bin/zsh, your task is completed.
To change it back to bash, issue the following command on terminal.
chsh -s /bin/bash
Verify it again using echo $SHELL
. Then result should be /bin/bash.
For Bash, try
chsh -s $(which bash)
For zsh, try
chsh -s $(which zsh)
if it is just a temporary switch
you can use exec as mentioned above, but for more of a permanent solution.
you can use chsh -s /bin/bash (to switch to bash) and chsh -s /bin/zsh (to switch to zsh)
You can easily switch back to bash by using command "bye"
