After upgrading to Catalina and encountering the zsh upgrade reminder when launching Terminal, I've decided to switch to zsh.

The default interactive shell is now zsh.
To update your account to use zsh, please run `chsh -s /bin/zsh`.

However, I'm having trouble getting Terminal/zsh to recognize the .zshrc startup file located in my home folder. ~/zshrc isn't loaded on launch, and executing source ~/.zshrc returns source: no such file or directory.

The file only contains one line, an alias tying python to python3.

Finder showing .zshrc presence next to an open TextEdit window of the file Terminal showing the lack of any aliases and the failed source command

    Please run ls -ltra to check whether the file exists in your home directory, see example below: ``` ls -ltra ~/.zshrc -rw-r--r-- 1 user staff 475 Jul 30 22:52 .zshrc ``` Thanks.

  • If the source command says that the file does not exist, the file really does not exist. Jun 3 at 10:02

The issue turned out to be that .zshrc had a hidden .txt file extension. Somehow it was automatically named .zshrc.txt, probably when I used TextEdit to edit it, and source doesn't infer the text extension. Finder also doesn't display the .txt extension by default unless you inspect the file, so I hadn't noticed the issue.

  • Well, if the file has a different name, of course zsh does not find it. The problem seems more to be related to your text editor, which adds a .txt without your permission, and a weird setting of your Finder, which hides extensions. This is something I would solve once and for all, otherwise it will bite you again someday. Jun 3 at 10:04

Somewhat similarly, my terminal/zsh wasn't recognizing my .zshrc file also, so running source ~/.zshrc helped me find that my zshrc file was formatted improperly (it contained spaces before/after an equals symbol in alias g="git").
