The following command will create files: $lastnameCAT -s filel file2 file3 file contains: This is the content of file 1. This is the content of file 2. While the following command will create file3: $last nameCAT -e filel file2 file3 file contains: This is the content of file 2. This is the content of file 1. Your command should print proper error messages in case the user does not give the command the right number of arguments or the wrong flag (anything other than '-s'or'e'); SlastnameCAT -e file2 filel Error!
