Mac terminal -bash command not found?

Question

I'm completely new to using terminal, and while trying to use brew to install some stuff, I did something to PATH. Now if I tell it to do something it always returns

-bash: blah: command not found.

Is there any way to reset something to fix this? What should I do?

Solution 1

Your path is usually set in either your .profile or .bashrc file. These are found in the root of your user's home directory.

You should be able to fix them by running these two commands in the terminal. They contain the default executable paths

export PATH="/usr/bin:/bin:/usr/sbin:/sbin"
export PATH="/usr/local/bin:/usr/local/sbin:$PATH"

Solution 2

You can set your path this way:

export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

and you can always add other directories if you want. Hope this helps.
