This is about keeping a directory free of "junk" files. To be specific, we want to remove files that are backups and auto-saved versions. Create a file "cleanup.sh". Use this file to write your script. Develop a Bash procedure called cleanUp() that deletes all backup and auto-save files from the given directory. Assume that names of back up files end in either (i) or (ii) .bak, and (iii) auto-save files have names beginning with a #. Develop a test harness that tests the cleanUp() procedure. The test() procedure should (i) create a new directory named TEST in the current directory, create a few files (say a 4 each of names chosen by you) that fit the three categories of junk files in TEST, (ii) Is -I the TEST directory, (iii) invoke cleanup TEST, and again (iv) list-long the Is -I the TEST directory. For your answer, Copy-paste the result of Is -I in the TEST directory prior to running your script. Copy-paste the command line you used to run your script. Copy-paste the result of Is -I in the TEST directory after running your script. Copy and paste your "cleanup.sh" file to the answer field for this
