How can I permanently remove an added alias from zsh (MacOS Terminal)?

Question

I'm using MacOS and had the issue that my Terminal didn't react to the 'python' command, so I tried out what was recommended here (manually adding an alias to zsh with echo "alias python=/usr/bin/python3" >> ~/.zshrc).

Turned out this wasn't the perfect solution in my case, so I'd like to reverse it.

I tried the 'unalias' command, but this only works for the length of the Terminal session. If I reboot Terminal, the alias is still there. Is there a permanent way how to delete this manually added alias?

Answer 1

1. Open the .zshrc file using any text editor.
2. Go to the bottom of the file.
3. Delete the line that says `alias python=/usr/bin/python3"
4. Save and exit.

Voila.

The echo command combined with >> is just appending alias... to the bottom of the .zshrc file, deleting this line will get rid of the alias permanently.
