Subject: Shell Scripting Practice A File: practice-script-a Create File practice-script-a that: 1. Accepts any number of userids on the command line 2. For each userid, display the userid, PID, CPU time, and current command for each process owned by that userid Your output should look similar to this example: practice-script-a doug.jones User: doug.jones PID: 8748 TIME: 00:00:00 COMMAND: /usr/lib/systemd/systemd --user User: doug.jones PID: 8749 TIME: 00:00:00 COMMAND: (sd-pam)    User: doug.jones PID: 8750 TIME: 00:00:00 COMMAND: sshd: doug.jones@pts/5 User: doug.jones...

Finally, write a script named word_counts.sh that prints out how many words are on each line of standard input, as well as the total number of words at the end. The script should take no arguments. Instead, the script must work by reading every line of standard input (using a while loop) and counting the number of words on each line separately. The script is intended to work with standard input coming from a pipe, which will most often come...

Design, code, and test a program that includes a function of type double called divbaby that accepts two double arguments (you must write the divbaby function). When called, your function will return the first argument divided by the second argument. Make sure your function includes a decision statement so that it can't divide by 0--if the caller attempts to divide by 0 the function should return a value of -2.0. Your program should call divbaby then display the value returned...

Place the code you developed in Lab 2 to obtain a diameter value from the user and compute the volume of a sphere (we assumed that to be the shape of a balloon) in a new program, and implement the following restriction on the user’s input: the user should enter a value for the diameter which is at least 8 inches but not larger than 60 inches. Using an if-else...

It will have a method that will accept three arguments consisting of a string and two numbers example ("+", 4, 5) where the string is the operator and the numbers are what will be used in the calculation. It doesn't need an HTML form, all the arguments are put in through the method. The class must check for a correct operator (+,*,-,/), and a...
