c. For an invalidly named file that starts with file and is followed by any characters that include some non-binary digits: i. echo the following output to the terminal screen: invalid filename non-binary characters after 'file' ii. Move the invalid file to a subdirectory called CATEGORY3 (the script should only create the directory here if it does not already exist and also only when a file in this category is found). d. For an invalidly named file that does not start with file: i. echo the following output to the terminal screen: invalid filename does not start with 'file' ii. Move the invalid file to a subdirectory called CATEGORY4 (the script should only create the directory here if it does not already exist and also only when a file in this category is found). 8. If the command-line argument specified directory contains no files: a. echo the following output to the terminal screen: The directory dirname contained no files... b. exit the script This also means if you run the script twice, the first time should process any files, displaying the outputs specified in requirement 7 above, renaming where appropriate, and moving files to specified category subdirectories. Running the script for a second time (with the same directory argument) will produce the output specified in this requirement (requirement 8), as all files should have already moved to subdirectories. Your output should never "process" or mention the subdirectory names. Binary to Decimal Renaming As previously mentioned, a validly named file will have the form fileABCDEFGH, eg file01010111 Your script must implement an algorithm only using commands and syntax as discussed in practical classes. Your solution is restricted (i.e not allowed) to use the shell "builtin" conversion .g. echo $((2# 101010101)) c.
