hello, for question where we are prompted to sort the arcade.csv file and so far I have copied what we did to the alice in wonderland text in week1 tr -cs '[a-zA-Z]' '\012' < arcade.csv | sort -k5n |uniq -c | sort -h | less but it is printing out the numbers seperate to their letters/characters that make up the passwords. how do I sort the data into columns so that sorting can be assigned to specific columns?
