using pipe and several commands you have used so far that will list only the names of the users who have logged in to the system in the current month, sort the output, and remove any duplicate name entries
So I have to use last first in this command and I've figured out the format my professor wants it in, something like this
Code:
last | cut -d' ' -f1,15 | sort > check | uniq -c
.... and I never can get it right, when I just last command I get something like
Code:
