Terminal prints all brew commands whenever I open terminal

Yes, I think there is some issue with using zsh shell. Because I switched to bash and it didn't print anything.

I did echo $SHELL and it showed /bin/zsh. I didn't understand what exactly I need to do in this case.

The following command shows which shell you are using:

echo $SHELL

You are using zsh.

Exactly what you need to do next is to review and debug the contents of your login-related scripts.

This will entail learning more about the command line and the shell.

Here are the zsh-related scripts:

Review each of those for a brew-related command or script.

Your existing login scripts have calls to other scripts (whether added by you or others or other installed apps or tools), and you need to review each of those other scripts, too.

You also have two package installation managers installed, which can make for a more complex command-line environment; both SDKMAN! and Homebrew. SDKMAN! is not one I’ve used. Homebrew, yes, I have and do use that. (I see a total of three references to SDKMAN! around here in ASC too, and two of them are from you here.)

There are books and online resources on learning zsh, likely also videos and classes. Homebrew has some doc, but the issue here looks to be with a brew command, which should be fairly visible in whatever shell script is being run, and running awry.

I have been running Homebrew for years and it does not insert any command into any SHELL dot file. Doesn't even modify the PATH variable, which you will need to do on your own if you want to access and /opt/homebrew/bin commands on an Apple Silicon Mac.

Launch the Terminal. Enter the following command so there is no doubt about the SHELL you are using:

echo $SHELL

If that says /bin/zsh, then you should create and enter your SHELL PATH and other content in the ~/.zshrc file. If it is /bin/bash, then use ~/.bash_profile.

In either SHELL case, you should not have any function, alias, or command in your dot file that runs brew.

We cannot help with any Google SDK or related commands, or your not following directions in your ~/.zshrc file.

This happens because brew must have installed some command to run in one of the files that run automatically - perhaps in ~/.bash_profile (if your shell is bash) or ~/.zshrc (if your shell is zsh), but it could be in other files.

You may do

cat ~/.bash_profile

or

cat ~/.zshrc

and tell us what you get

Ok, then whatever we might do to .bash_profile is immaterial, and instead we need to focus on the zsh files.

What is in ~/.zshrc ?

Is suspect that the two lines at the end may be causing this.

To make sure, you could edit this file and prefix those final lines (the ones starting with eval) with the comment character #:

# eval "$(/opt/homebrew/bin/brew shellenv)"

# eval "$(/opt/homebrew/bin/brew shellenv)"

then save the file. Quit Terminal and start again. Does it still behave the same way?

And are you sure that the shell you are running is actually bash?

It might be zsh.

If you type

ps

at the terminal prompt it will tell you about the processes running. Do you see one or more zsh, or bash in there?

In addition to the above… If you’re really running Ventura 13.0.1, update to 13.2.1.

Just as additional information, should you decide to remove it entirely:

It looks to me that the problem may be in the file that is read and executed by the script, apparently twice.

That's this file:
