I accidentally unset all the directories of $PATH while trying to add a new one in ~/.bashrc. I opened a new terminal window as I was editing and now $PATH is empty. I'm worried if I boot from another drive to find the $PATH I won't be able to boot into this drive again.
Basically, what is the default result of echo $PATH?
How will I make this /media/De Soft/mongodb/bin PATH variable permanent?
Everyone is saying export PATH=$PATH:media/De\ Soft/mongodb/bin to your ~/.profile, or .bashrc, or .zshenv depending on your shell. I don't know what is ~/.profile, or .bashrc, or .zshenv. And what they do actually?
And how will I add export PATH=$PATH:my/path to my .profile/.bashrc/.zshenv?
