Write a script called ChangeExtensions that accepts two file name extensions as arguments, and renames all files with the first extension to have the second extension. For example, Change Extensions txt text would change all .txt files to be .text files. Hint: read the man pages for basename. The script must check that two arguments have been provided, and exit with an error message if not. The script must check if there are any files with the first extension, and exit with an error message if there are none. If all goes well, a message must be output for each filename that is changed.
