so the other night i was working in the terminal and all of a sudden all of my commands stopped working so normal stuff like ls and pwd present working directory none of that worked and if thatamp;#39;s happening to you let me show you how to fix it so why this happened is that you probably reset your path variable so your path variable is where the shell where your terminal goes to look for the different commands so like ls and you can see where that lives at like which ls it says oh thatamp;#39;s located at bin slash ls thatamp;#39;s thatamp;#39;s where to find the code to run this command now if you reset your path variable your shell doesnamp;#39;t know where to look so if you just uh echo your path variable you can see your local your paths what they currently are and remember each one of these colons this is an array so each this each is a different path so this is a path this is a path so each all these are locations for different different uh commands you can use now leta
