(this is a linux question) 6. (TLCL 11 - 2pts) A student in your class is practicing using the shell and environment variables. First they add an environment variable alpha, and they set it equal to 1. Then they edit their shell profile to add the alpha variable, setting it to 0. They also add a variable called beta to their shell profile, and set it to 0. They also add a variable called gamma, and set it to 0. Then they reload their shell profile. Finally they add an environment variable beta to their environment variables, and set its value to 1. If they run the following commands in their terminal what do you expect the outputs to be? (TLCL 11) 1. echo alpha 2. echo beta 3. echo $alpha 4. echo $beta 5. echo $gamma 6. printenv | grep "alpha\|beta\|gamma".
