Question

I need to create a UNIX program for this assignment

In this assignment, you are to create an "archive" utility. It is a simple way to have some version control. You've created software projects before that change and grow over time. You might have several different copies of it (let's assume that it's all in one file). Perhaps before making major changes, you make a back-up copy, in case you later decide to revert to the earlier version. The idea is this: make a shell script program, called archive, that creates a back-up version of a file.

Notes:

• This program should not be confused with the "tar" command.
• The move command (mv) will preserve the time-stamp.
• You will need to turn in a log file showing your program (i.e. with cat). Show that it works for several test cases.
• You may be asked to meet to demonstrate your solutio

Answer 1

Snehanshus-MacBook-Air:Desktop snehanshusuman$ cat archive.sh

inputfile=$1
currentdate=`date +%m-%d-%Y`
mv $inputfile $inputfile-$currentdate

Snehanshus-MacBook-Air:Desktop snehanshusuman$ touch test

Snehanshus-MacBook-Air:Desktop snehanshusuman$ ls -lrt test

-rw-r--r-- 1 snehanshusuman staff 0 Oct 3 16:05 test

Snehanshus-MacBook-Air:Desktop snehanshusuman$ ./archive.sh test ###name of the file you want to archive.

Snehanshus-MacBook-Air:Desktop snehanshusuman$ ls -lrt test*

-rw-r--r-- 1 snehanshusuman staff 0 Oct 3 16:05 test-10-03-2020

Please let me know if I misunderstood the requirement.
