$ grep/ sbin/nologin$/etc/passwd| cut -d “:”-f1| short| less

explan the output

Expert Solution

if we part apart from the syntax, so first we display all the lines which contain nologin word inside passwd file.

Now we separate the first column only using the cut command with delimiter : colon with column f1

now sort this data using sort command from ascending order

and at last less command is for display only till terminal shows and remaining lines will be shown by pressing enter

Thanks

This lab will explore the password files. a) Open a terminal window and type less /etc/passwd. Which line describes the root account? b) Type ls –l /etc/passwd. Who is the owner of the passwd file? What are the permissions? c) Type less /etc/shadow. What is in the password filed for most of these accounts? d) Type ls –l /etc/shadow. Who owns this file and how do the permissions differ from the /etc/passwd file? e) Type cat /etc/default/useradd. What is the...

can you please do the following? (8) Step 8: type the following command: sort /etc/passwd | head -5 What is the output? Notice that this pipe can be simplified cat /etc/passwd | head -5 What is the output for this? You could accomplish the same thing more efficiently with either of the two commands: head -5 /etc/passwd head -5 < /etc/passwd (9) Step 9: The command displays all the files in the current directory sorted by file size ls -al...

F1 plants that are medium in height are produced by crossing tall with short parents. When the F1 plants are self-fertilized, the F2 offspring consist of different heights ranging from short to tall with most plants having some intermediate height. Now you want to further study the genetics of this trait and, for that, you grow the F2 offspring in a field location in the summer of 2019 (all in the same field which is subject to similar conditions and...

TRUE OR FALSE a) If output is less than potential output, unemployment will encourage workers to accept smaller raises, which brings inflation below expected inflation. Eventually, expected inflation will fall, which allows firms to lower the inflation rate. As the real money supply rises, investment and output rise. The process continues until the economy is in medium-run equilibrium. b) It is easier to stabilize the economy if expectations remain anchored. c)It is easier for central banks to stabilize the economy...
