write the code to lookup, add and remove phoneentries from the phonebook text file . These are the code we use for the lookup, add and remove in the case statement.(Lookup)# Look someone up in the phone bookgrep $1 phonebook (add)echo "$1 $2" >> phonebooksort -o phonebook phonebook (Remove)grep -v "$1" phonebook > /tmp/phonebookmv /tmp/phonebook phonebook Write a complete Bash script which will accept up to three command-line arguments: the first one is either (lookup, add or remove), the second one is a name enclosed in single quotes and the third one (if doing an add) is a phone number enclosed in single quotes. Using a case statement to match on either lookup, add or remove, the script should then perform the requested operation. Again here, you should first check for null arguments before continuing with the rest of the script or requested operation. In addition, the person may not be in the phonebook for lookup or remove so, you need to account for this.

1. Use the RAND function and the Copy command to generate 100 random numbers. a. What fraction of the random numbers are smaller than 0.5? b. What fraction of the time is a random number less than 0.5 followed by a random number greater than 0.5? c. What fraction of the random numbers are larger than 0.8? d. Freeze these random numbers. However, insteadof pasting them over the original random numbers, paste them onto a new range. Then press the F9 recalculate key. The original random numbers should change, but the pasted copy should remainthe same
Using Bash, write a script that takes two files of unique numbers and displays the difference between two lists (without using grep). For example, File 1 contains: 1 2 4 6 File 2 contains:1 2 89 6 7 Output should be: only in file 1: 4 only in file 2: 89 7
Please answer the following Bash question, please show your output as well. 1. Write a Bash function named ‘Generate-ID' that generates all possible UGA student id start with 900. The output should be saved into a file named studentID.csv. 2. Write a Bash function named ‘Find_word’ that read wordlist.txt file to find all words end with “ing” and output these words to WordEndIng.csv. 3. The auth.log file (path: /var/log/auth.log) and syslog file (path: /var/log/syslog) are two of the most important log files in Linux. Generally, adversaries target these files so that system administrators couldn’t track what attackers are doing. Write a function named get-linuxlog() that reads all the above two files and stores them into a file named linuxeventlog.txt (Hint use the ‘cat’ command)

This needs to be done using Linux bash shell script. 2. Write a shell script display_digits to display all digits ( from leftright ) if the input is an integer, otherwise, show that the input isnot an integer, e.g.,"display_digits 1978 show "1 9 7 8", and"display Hahah12" should display "Hahah12 is not an integer"Hint: you will likely need to use the pipe | , echo command, and cut -ccommand.
