Fixing zsh: command not found: ssh -Y on Mac Terminal

If you are using the zsh shell on your Mac Terminal and encounter the error message "command not found: ssh -Y", don't worry! This article will guide you through the steps to fix this issue.

The "command not found" error occurs when the zsh shell cannot locate the ssh command. This can happen due to various reasons, such as missing system paths or incorrect configurations.

Step 1: Check SSH Installation

First, make sure that SSH is installed on your Mac. Open the Terminal and type the following command:

If SSH is installed, you will see a prompt asking for the SSH password or passphrase. If you receive a "command not found" error, proceed to the next step.

Step 2: Update your $PATH variable

The $PATH variable contains a list of directories where the shell looks for executable files. If the SSH executable is not in one of these directories, the "command not found" error occurs.

To check the current value of your $PATH variable, run the following command:

Add the following line at the end of the file:

Save the file and close the text editor. Then, run the following command to apply the changes:

If the SSH command works without any errors, you have successfully fixed the issue. If not, proceed to the next step.

Step 3: Reinstall SSH

If updating the $PATH variable did not resolve the issue, you may need to reinstall SSH on your Mac. Follow these steps:

1. Open the Terminal and run the following command to uninstall SSH:
brew uninstall openssh
2. Once the uninstallation is complete, reinstall SSH by running:
brew install openssh

After the installation is finished, try running the SSH command again to see if the issue is resolved.

By following these steps, you should be able to fix the "command not found: ssh -Y" error on your Mac Terminal. If you continue to experience issues, it is recommended to seek further assistance from a technical expert.
