Terminal commands can not be found OSX

问题

A majority of terminal commands don't work, for example .

ls sudo vi

with the error -bash: ls: command not found my path is echo $PATH “/Users/username/usr/local/bin I get the feeling that “ should not be there but not sure how edit it.

What should the path be and how do I get the path to stay the same?

You need to add more paths to your $PATH variable. Try running whereis ls and check where is the binary of the command.

You can add more paths like this: export PATH=$PATH:NEW_PATH
