5. [8] Write a bash script which takes any number of file names as command line arguments and prints whether each file is readable or not. Print a summary line as shown in the sample below. Sample session: $ ./readcheck assign1 chapter2 blog-jan assignl is readable chapter2 is not readable blog-jan is readable. Summary: 2 of 3 files are readable. $ Attach a printout of your code and its output. Test cases must include at least three filenames some of which are readable and some are not. There are penalties for missing output. [When checking for a non-readable file, you can simply give the name of a file that doesn't exist (chapter2 in the above example)].
