Write a DOS Batch File Write a DOS Batch File to the following exact specifi­ cations. For full marks, do not include any non-essen­ tial DOS commands that are not required by the specifi­ cations. (Don't do things that are not requested!) The exact specifications are: (1) Start the batch file with two comment lines. The first comment line should contain only your Algo­ nquin email userid. The second comment line should contain only your name. (2) Make drive D your currently logged-in drive. (3) Make the root directory of the current drive the current working directory. (4) Create a new directory named DIRBDIR located under the root of the B drive. Create this directory on the B drive. (5) Create a subdirectory in the current working directory named DIRLIST. (6) Make drive letter A your currently logged-in drive. (7) Produce a recursive directory listing of the root directory of the D drive and redirect the output to a directory listing file named SUBFOL in the root directory of the current disk drive (do not use any drive letter for this output pathname). Use a BAK extension on the output listing file name. (8) Make drive letter C your currently logged-in drive. (9) Put a copy of the output directory listing file you created earlier into each of the two new directories you just created: Put one copy of the output directory listing file into the existing DIRBDIR directory; put another copy of the file into the existing DIRLIST directory. Use a TXT file name extension for the copied version of both files. -------------------------------------------------------- REM alleni REM Ian Allen D: CD \ MD B:\DIRBDIR MD DIRLIST A: DIR D:\ /S >\SUBFOL.BAK C: COPY A:\SUBFOL.BAK B:\DIRBDIR\SUBFOL.TXT COPY A:\SUBFOL.BAK D:\DIRLIST\SUBFOL.TXT
