2 . Next up is changing the theme setting in our ~/.zshrc. For VI or VIM users simply type: vi ~/.zshrc For people that are not familiar with the vim commands or just prefer a simple text editor, type: open ~/.zshrc In our ~/.zshrc, you will find a paragraph that looks like this (usually third paragraph from the top): Now open your .zshrc file: open ~/.zshrc paste the copied code at the end and save it. Then RUN the below command, source ~/.zshrc When on iterm2 or the terminal, you should see a (base) pop up in there Just run open ~/.zshrc on the command line, which will open your .zshrc file in your default text editor (usually TextEdit) and, as long as you save it as plain text, you’ll be fine. It doesn’t really matter where you paste it into your .zshrc file, as nothing else in there depends on it. Step 5: Apply Changes. Run the below command in terminal to apply changes to Zsh shell. Copy. source ~/.zshrc. Now if you do a java --version, you should see that you have the JAVA_HOME JDK being used. [Macbook % java --version openjdk 21 2023-09-19 OpenJDK Runtime Environment (build 21+35-2513) OpenJDK 64-Bit Server VM (build 21+35-2513, mixed And according to the documentation I need to change the ~/.zshrc file and total a ZSH_THEME value: Once yourself find a theme this you want to use, you will need to edit the ~/.zshrc file. You'll see into environment variable (all caps) in there that looks like: ZSH_THEME="robbyrussell" The problem is ME don’t know where in find the ~/.zshrc If you're trying to debug a script, then don't use set -x on the terminal (that's debugging the shell running in the terminal). You can instead start the script with the -x option to the interpreter (e.g., zsh -x [] ). If, for example, you have a zsh script named ex.zsh, then you can do: Open Mac Terminal, Move to /etc directory: cd /etc You will find a zshrc file here (this is not a hidden file), Open this file using nano or vim editor: vi zshrc Note: If you make any changes in the /etc/zshrc file, the changes will be applied to all users on the Mac even if the .zshrc file is not available for any user or now. - Facing issues? On starting a new shell just run the command source ~/.zshrc by configuring in the. Preferences -> Profiles -> Select Default Profile (default profile will be starred) -> General -> Command -> Select Login Shell -> Send text at start: Enter the value source ~/.zshrc.

It might be a good moment to make a copy of the .zshrc file first to return to the original state. 3. 4. You're missing /. Your command source ~.zshrc tries to lookup the home directory for a user called .zshrc. The source command would presumably attempt to execute that user's home directory - and fail. What you probably meant was this, which looks up your home directory with ~ and then source can execute the commands in a file .zshrc in there. tatJe3.
