Question

Suppose you were to type the following commands at the command line (from any location in your directory): 1 >$ mkdir expansions 2 >$ cd !!: 3 >$ touch a{b,c,d}e z{a,i}{p,t} 4 >$ unalias lsh 5 >$ alias lsh='ls -a' 6 >$ alias lhl='lsh -l' 7 >$ files1=a 8 >$ files2="a" 9 >$ echo "[td]" > list 10 >$ cp ./testFiles/test . 11 >$ rm e What follows are three commands. For each one, you may assume they were entered as command # 12. A partial list of expansions has been provided for the first 2 problems. Your job is to fill in the missing expansion types and results of applying the expansions. Sometimes you will have to fill one or the other sometimes you'll have to fill in both. For problem 3 you will have to fill in every step. You may work in pairs/groups on this but everyone must turn in their own worksheet on the due date. Command 12: lhl cat ???"" Expansion Alias Result lsh -l `cat ???"" ls -a -l `cat ???"" Command (Applies expansions within command) Expansion Result ls -a -l (Runs the command) ls -a -l Final Command: Command 12: !!:0 $files1 Expansion Result rm $files1 FINAL COMMAND: Filename rm Name: Graded By You should list each expansion step as shown in the previous examples.
