LINUX OS:

Create a script where the script reads the existing custom environment variable SCCDEVINFO (created with 'export SCCDEVINFO=value' which you will need to create to demostrate the script), which will contain the full path to a file. Each line in the file will be the full path to an existing file, so loop through the file and read each line one at a time and create a backup of that file in /bkp if the file doesn't already exist in /bkp add the date in the format yyyy-mm-dd (hint use the 'date' command) to the end of the file name saved in /bkp. Once completed, take a screenshot of the source code of the script, and of the script executing, to execute the script you will need to create your own sample input, please include the sample input as part of your execution screenshot.
