1. (a) Write a script that prints all input lines.(b) Write an awk command that prints the total number of fields in the file?

2. (a) Write a script that prints the eighth line(b) Write an awk command to simulate following shell command CP file1 file2

3. Create an inventory file for the following data( do not include the columnheads only the data) call it as ch12s3f1Partno Price Quantityonhand Reorderpoint minimumorder

0123 1.23 23 20 200234 2.34 34 50 253456 34.56 56 50 104567 45.67 7 10 55678 6.78 75 75 25

(a) Create a script to prepare an inventory report. The report is to contain the partno,price, Quantity on hand, reorder point, minimum order and order amount. (b)The order amount calculated when the quantity on hand falls below the reorder point, Is the sum of the reorder point and the minimum order less than quantity on hand . (c) Also provide a report heading such as “Inventory Report” ,heading for each column and “End of report” message at the end of report. (d) Print the report4 . Create a script that sends the contents of message file to every body who has logged inPreparation: Create a file shortly friendly message and mention that this is a test message that should beDiscarded by the receiver.Script:Script name: message.scrArguments: one argument ,a message file

Validation: (i)Ensure that exactly one argument is entered(ii)Ensure that argument is readable filenameBody Section: Create script that uses awk to create a temporary file containing the usernames of thoseUsers who are logged into the system at this moment. Then send the message contained in theFirst argument to every logged –in user.Note that a user who has logged in more than once should Receive only one messageTestting the Script:1.Test the script with no arguments2.test the script with two arguments3.test the script with one argument that is not readable file.4.Test the script with one valid argument You should include yourself in the receipent list. Chech to see if you have received the message.5.) write a Script to backup a list of filesPreparation: (i)create a file and type it in the list of files(in your home directory) that you want to backup.(ii)create a directory in which you will store the backup files.Script: Script name: backup.scr Arguments: A filename and directory.The file name holds the list of files that shold be backup. The directory is where the backup file should be stored.

Validation: -ensure that exact to arguments are entered -check that the first argument is the name of file that exists. - check the second argument is the name of directory that existsBody Section:

Create backup files for all files listed in the first argument. The backup files should have

same name of as original file with extension ‘.bak’.they shold be copied to the directory given as

second argument.

Testting the Script:
