$PATH

• $PATH is your environment variable
• It tells your system where to find programs

To see your path variable type this command

$ echo $PATH

You should see something like this

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

Now look at etc/environment, you should see

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
