The Task: Based on the lab activities as well as external readings, each group needs to write a Bash script that will implement menus using 'dialog' or any other utility. Create function for each action, e.g., to show Calendar on screen create function show_calender(). Menu-items and action according to select menu-item are shown as follows: Menu-item Date/time Purpose To see current date and time Calendar To see current calendar Delete To delete selected file Action for Menu-Item Date and time must be shown using infobox of dialog utility or otherwise Calendar must be shown using infobox of dialog utility or otherwise and it should have the flexibility of choosing any particular date from the calendar to add any relevant information if needed. First ask user name of directory where all the files are present, if no name of directory given assumes current directory, then show all files only of that directory. Files must be shown on screen using menus of dialog utility or otherwise. Let the user select the file, then ask the confirmation to user whether he/she wants to delete the selected file, if answer is yes then delete the file, report errors if any while deleting file to user. Exit/Stops the menu driven program i.e. this script Exit To Exit this shell script Your shell script should also show the following five system configuration information: 1) Your operating system type, 2) Computer cpu information, 3) Memory information, 4) Hard disk information, and 5) File system (Mounted). Try to show as much detailed information as possible for each of the above five cases. These five example should be written in a separate shell script file. In addition to writing the script, each group needs to show that everybody has contributed equally in the project work. There should be plenty of comments throughout the script which would explain all the relevant steps in the scripts
