How do I reset and put the zshrc file back to default?

Question

/Users/ello/.zshrc:source:3: no such file or directory: 
/Users/ello/Projects/config/env.sh
Ello-MacBook-Pro% /Users/ello/.zshrc:source
zsh: no such file or directory: /Users/ello/.zshrc:source
Ello-MacBook-Pro% /Users/ello/.zshrc
zsh: permission denied: /Users/ello/.zshrc
Ello-MacBook-Pro%

This has been happening, after I foolishly edited the .zshrc file. All that remains in the file now, after attempting to reset the shell, is this:

# Created by newuser for 5.3.1
# Add env.sh

How do I undo everything, reinstall zsh, or remake the .zshrc file?

This is on macOS Sierra.

Edit: I reinstalled oh-my-zsh, leading to this message:

# supports them.

Answer 1

There is no such thing as "default". The best you can do, is check if your system has /etc/skel/.zshrc. If yes copy that into your home.

When you log in first time, your home is populated with everything from /etc/skel.

Answer 2

zsh itself does not have a default user configuration. So the default ~/.zshrc is actually no ~/.zshrc.

But as you tagged the question with oh-my-zsh I would assume that you want to restore the default oh-my-zsh configuration. For this it should be sufficient to copy templates/zshrc.zsh-template from your oh-my-zsh installation path, usually ~/.oh-my-zsh:

cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

You may want to backup your current ~/.zshrc beforehand. Although it may have some problems now, you still might want to look up some settings once you reverted to default.

My dumass decided to just put a crash command into the zsh file. Now when I open the terminal, it just kernel panics. so I just deleted the config file using rm -f ~/.zshrc* and by default, it just got replaced with another copy. So good luck.

Answer 4

You can copy .zshrc template from

https://github.com/ohmyzsh/ohmyzsh/blob/master/templates/zshrc.zsh-template

And copy and paste all content in to ~/.zshrc

Answer 5

Make it your default shell using this command:

 chsh -s $(which zsh)
