Hint: Since the number of words in a name varies, we need to create an intermediate that has the last name first to simplify sorting. After sorting, we no longer want that last name as the first value.
Create a bash file named p3a.bash to create the sorted file. Besides the shebang line, there should be only one other line in the bash file. That line must use pipes between the steps.
These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.# as the hint says, we join the last field from each row at the beginning of the row using a different delimiter - pipe in this case
# then we sort on the 1st field by pipe
#and discard the 1st field before printing the 2nd field with delimiter...
