A)When an operating systems is booted B)When a running process makes fork system call C)When the user runs a new program D)When a running process is blocked +1 E)Batching process in batch system1. Write the command(s) needed to list all processes running on your system, showing a full set of columns and pipe that output to the less command so that you can page through the list of processes. 2. Write the command(s) needed to list all processes running on your system, sorted according to memory utilization. 3. Assume that the process gedit is running. Explain the steps and commands needed to kill this process. 4. Write the command(s) needed to start Firefox with a nice value of 5. 5. Write the command(s) needed to change the niceness of Firefox to 7. 6.

- Which events can change the state of a thread t from Locking object o to Enabled(that is, ready to run)? Question 18 options: a) if no other thread holds the lock on o and the system grants t the lock on o b) if t was Waiting on object o and another thread th executes o.notifyAll() c) if another thread th holds the lock on o and executes the static yield method d) if another thread th executes t.interrupt() e) if another thread th executes t.start()Suppose we run a foreground process in a shell and it's assigned PID 1234. Assume the process doesn't block or ignore SIGTERM.We hit ctrl-z. Then we run "kill 1234". What will happen? a) SIGTERM is discarded since process 1234 is stopped b) process 1234 receives SIGTERM and terminates c) the kill command fails d) SIGTERM is marked as a pending signal for process 1234Suppose that we have access to the world database, on the server something.com with username "Jim123" and password is K@$t0r1@.We need to create in any programming language, an application that will be connected to the above database and will perform the following actions.The user, that is you, will choose from an appropriate menu like the one shown in the picture.1. Connect to the system of the database.2. Display of data3. Data entry4. Update data5. Start transaction6. Exit the System.In the meantime you will have created appropriate triggers that will inform appropriate table for the actions that have been taken. The names of the triggers will be formed with the name that you as a user have followed from thetrN with N (1,2,3,...), example jsinatkas_tr4. Also in the transaction process you will make sure to lock, if needed the the table or tables in which you are going to enter or update data them. This lock will last as long as it is necessary to complete your action. This will be…
- What does the following command do? ps-ef | grep dfluse O a. It lists all of the processes in full format, except those processes with the text dfluser O b. It lists all processes in full format and displays only those that have dfluser somewhere in the text O c. It add the grep process to the system, which belongs to dfluser O d. It lists all of the print jobs associated with dfluser O e. It opens the print queue and deletes all jobs except those belonging to dfluserLinux allows tasks to be scheduled and executed using cron and crontab. Crontab will utilize the job scheduler, while cron will execute the tasks. (a) Write a Linux shell script to capture all the processes run by a user named user1 as well as the current date and time before appending these information to a file named traceLog.txt. Next, move the traceLog.txt file to a directory named backup. Finally, kill all processes owned by user1 and all processes named torrent. (b) Configure the crontab to schedule the execution of the shell script in question (a) above, assuming that the shell script is located at /home/admin directory. The shell script should be executed at every two hours daily. Append the current date and time followed by the list of all users currently logged into the Linux system to a file named userLog.txt every 40 minutes. Assume that the userLog.txt file is located at /home/admin directory. Schedule a broadcast message every hour on the 28th day of each month to all…1.)Why is this code not thread safe? 2) What issues could arise if it is not fixed? 3) How you would fix it using what you learned about synchronization?
