C:\WINDOWS>HELP COLOR
Sets the default console foreground and background colors.

COLOR [attr]

 attr        Specifies color attribute of console output

Color attributes are specified by TWO hex digits -- the first
corresponds to the background; the second the foreground.  Each digit
can be any of the following values:

   0 = Black       8 = Gray
   1 = Blue        9 = Light Blue
   2 = Green       A = Light Green
   3 = Aqua        B = Light Aqua
   4 = Red         C = Light Red
   5 = Purple      D = Light Purple
   6 = Yellow      E = Light Yellow
   7 = White       F = Bright White

If no argument is given, this command restores the color to what it was
when CMD.EXE started.  This value either comes from the current console
window, the /T command line switch or from the DefaultColor registry
value.

The COLOR command sets ERRORLEVEL to 1 if an attempt is made to execute
the COLOR command with a foreground and background color that are the
same.

Example: "COLOR fc" produces light red on bright white



C:\WINDOWS>HELP COMP
Compares the contents of two files or sets of files.

COMP [data1] [data2] [/D] [/A] [/L] [/N=number] [/C] [/OFF[LINE]]

 data1      Specifies location and name(s) of first file(s) to compare.
 data2      Specifies location and name(s) of second files to compare.
 /D         Displays differences in decimal format.
 /A         Displays differences in ASCII characters.
 /L         Displays line numbers for differences.
 /N=number  Compares only the first specified number of lines in each file.
 /C         Disregards case of ASCII letters when comparing files.
 /OFF[LINE] Do not skip files with offline attribute set.

To compare sets of files, use wildcards in data1 and data2 parameters.



C:\WINDOWS>HELP COMPACT
Displays or alters the compression of files on NTFS partitions.

COMPACT [/C | /U] [/S[:dir]] [/A] [/I] [/F] [/Q] [filename [...]]

 /C        Compresses the specified files.  Directories will be marked
           so that files added afterward will be compressed.
 /U        Uncompresses the specified files.  Directories will be marked
           so that files added afterward will not be compressed.
 /S        Performs the specified operation on files in the given
           directory and all subdirectories.  Default "dir" is the
           current directory.
 /A        Displays files with the hidden or system attributes.  These
           files are omitted by default.
 /I        Continues performing the specified operation even after errors
           have occurred.  By default, COMPACT stops when an error is
           encountered.
 /F        Forces the compress operation on all specified files, even
           those which are already compressed.  Already-compressed files
           are skipped by default.
 /Q        Reports only the most essential information.
 filename  Specifies a pattern, file, or directory.

 Used without parameters, COMPACT displays the compression state of
 the current directory and any files it contains. You may use multiple
 filenames and wildcards.  You must put spaces between multiple
 parameters.
