Requirements wcat is passed in a file and will output the file on the terminal (use cat to familiarize yourself with how this should work) wgrep is passed 2 arguments, the first is the word or words that the user is looking for and the second argument is the file that should be searched (use grep to familiarize yourself with this) wzip is passed a text file and redirects it to a compressed zip file wunzip is passed a zip file and prints out the unzipped file in standard output E:\programc++>function_1 cat testAli.txt This is test for all. adadddddd adadadddd All I have and all line go and I hope they are working solid test it iss E:\programc++> E:\programc++>function2 grep is testall.txt This is test for all. solid test it is E:\programc++> E:\programc++>function3 zip testall.txt This is test for al2. adado adadad4 A12 I have and al2 line go and I hope they are working solid test it is E:\programc++>
