Terminal issues

Dear users,

I was using my terminal and then suddenly I realised the .zshrc file is missing then it's not able to run commands like vi, less ....

The error message is:

zsh: command not found: vi

All the programs, which I installed via brew and conda are no longer available. I'm not sure what's going on. I listed bin issuing

%ls /bin/

and the output is:

[ dd launchctl pwd test

bash df link rm unlink

cat echo ln rmdir wait4path

chmod ed ls sh zsh

cp expr mkdir sleep

csh hostname mv stty

dash kill pax sync

date ksh ps tcsh

I wonder if you have any suggestions. I am using macOS Monterey, MacBook pro M1, 2020 and I'm happy to share any information you may need to solve this problem.

Many thanks in advance.

Start with creating a /Users/username/.zshrc file, as it is not present by default. In a plain text editor (/usr/bin/vi), enter the following information if on an Intel Mac using brew:

export PATH=".:$HOME:/usr/local/bin:${PATH}"
PS1="%m: %~ %% "



and the following if using an M1 Mac and brew (requiring the /opt location):

export PATH=".:$HOME:/usr/local/bin:/opt/homebrew/bin:${PATH}"
PS1="%m: %~ %% "



The ~/.zshrc file will be read each time you launch the Terminal application, and if you want the PATH setting applied in the current Terminal session:

source ~/.zshrc

With the above, you should have access to any executable that you have installed on the Mac, and these PATH settings may need to be modified per your Python installation instructions.

Quit the Terminal application and relaunch it. Use /usr/bin/vi or /usr/bin/vim. Remember, if you are on an Intel box then homebrew uses /usr/local/bin, and on Apple Silicon, it wants to use /opt/homebrew/bin for installations and where it finds user installed commands.

Source is a Zsh or Bash shell built-in command and if it fails, then you are not finding the PATH to the shell, which should be /bin/zsh or /bin/bash for shells installed by the operating system. That /usr/bin and /bin are included in the default PATH variable.

The PATH environment variable implicitly has /usr/bin:/usr/sbin:/sbin:/bin:/usr/local/bin, so the only redundancy would be certain to precede it with /usr/local/bin to make it first in the search process and thus, locate commands there first.

Follow the instructions the Anaconda Python recommends for their PATH setup. If you are not on an M1 Mac, then you can forget about the /opt/homebrew/bin location. If brew installed openmotif correctly, it would be in the appropriate brew bin location and not left in the Cellar. That openmotif has a monster hierarchy of dependencies that you can see with this command:

brew deps --tree --installed openmotif

I have aliased this command in my ~/.zshrc:

alias brew_deps='brew deps --tree --installed "$@"'



Maybe you should print out the value in $PATH to see what it is. Sounds like you may not have the correct defaults in $PATH before .zshrc is processed so your $PATH is only contains the values you've added in the ~/.zshrc file. I tried looking for where macOS assigns the default $PATH value, but cannot locate it in the standard locations I'm familiar with on my Mac. I suggest creating a new admin user account, logging out your current user account, then logging into the newly created user account to print out the contents of the default $PATH to make sure it is correct. If it is incorrect, then you may have something major that is corrupt on your system.

echo  $PATH
