How to check Path variable in Mac OS

by Опубликовано

To check the PATH variable in macOS, you can simply echo its value in the Terminal. Here's how:

  1. Open Terminal.
  2. Type the following command and press Enter:
echo $PATH

This command will display the value of the PATH variable, which consists of a list of directories separated by colons. Each directory in the list represents a location where the system will search for executable files.

The output will look something like this:

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

This example shows a list of directories separated by colons. Each directory represents a location where executable files are searched for by the system.

To add /opt/homebrew/bin/ to your PATH in macOS, you need to modify your shell configuration file. macOS typically uses either the Bash or Zsh shell. Here's how you can do it:

For Bash:

  1. Open Terminal.

  2. Open your .bash_profile file in a text editor. You can do this using the nano text editor by typing the following command and pressing Enter:

    nano ~/.bash_profile

  3. Add the following line to the end of the file:

    export PATH="https://www.lexone.ru/opt/homebrew/bin:$PATH"

  4. Press Ctrl + X to exit nano, then press Y to save the changes, and press Enter to confirm the filename.

  5. After saving the file, you need to apply the changes to your current Terminal session. You can either close and reopen Terminal or run the following command to apply the changes immediately:

    source ~/.bash_profile

For Zsh (default shell in macOS Catalina and later):

  1. Open Terminal.

  2. Open your .zshrc file in a text editor. You can do this using the nano text editor by typing the following command and pressing Enter:

    nano ~/.zshrc

  3. Add the following line to the end of the file:

    export PATH="https://www.lexone.ru/opt/homebrew/bin:$PATH"

  4. Press Ctrl + X to exit nano, then press Y to save the changes, and press Enter to confirm the filename.

  5. After saving the file, you need to apply the changes to your current Terminal session. You can either close and reopen Terminal or run the following command to apply the changes immediately:

    source ~/.zshrc

Once you've done this, /opt/homebrew/bin/ will be added to your PATH, allowing you to run commands installed by Homebrew without specifying the full path.
