Write a bash shell script named user_details. sh that takes no arguments. the script should identify all currently active user on the system. for each of those users, the script should identify their full name (if one is present), the absolute path of their home directory, the total number of all files in their home directory (including files in subdirectories)(do not count directories as files for this case), the current number of processes owned by the user, and the top seven (7) processes by memory usage. example output of this script is as follows:
thor@muninn ~]$ user_details. sh
user: thor odinson (thor)
logged in: 2019-12-05 14: 27
home directory is /home/thor/
home directory contains 437 files and directories
thor has 84 processes
top 7 processes sorted by memory usage:
pid user ni virt res shr s %cpu %mem time+ command
8934 thor 0 2732664 283392 41524 s 0.0 15.1 1: 50.57 firefox
18590 thor 0 3159188 275080 13456 s 0.0 14.6 8: 29.25 gnome-shell
9253 thor 0 1889768 161468 6212 s 0.0 8.6 0: 03.92 wireshark

user: odin allfather (odin)
logged in: 2017-01-01 04: 20
home directory is /home/odin/
home directory contains 6539 files and directories
odin has 609 processes
top 7 processes sorted by memory usage:
pid user ni virt res shr s %cpu %mem time+ command
4 odin 0 2732664 283392 41524 s 0.0 11.1 91: 50.57 firefox

:you areto design the controller for alight that functions both as an ordinary light and also as a motion activated light and alarm. a. if the manual switch s is on, then the light l is on. b. besides the manual switch, there is a motion detector, m1, which activatesthis light. c.if motion is detected but the light is on anyway because s is on, only then a secondoutput a, an alarm, is turned on. d. the disable switch, d, disables the motion activated light and alarmbut leaves manual control operation of the light using switch s.(i)read the problem statement and clearly identify the inputs and outputs for the circuit you are designing. (ii)create the truth table for this system; include the light, alarm, switch, disable, and the motion sensor.(iii)draw a schematic of this system.
