FOR %variable IN (set) DO command [command-parameters]

  %variable  Specifies a single letter replaceable parameter.
  (set)      Specifies a set of one or more files.  Wildcards may be used.
  command    Specifies the command to carry out for each file.
  command-parameters
             Specifies parameters or switches for the specified command.

FOR /D %variable IN (set) DO command [command-parameters]

If set contains wildcards, then specifies to match against directory
names instead of file names.

FOR /R [[drive:]path] %variable IN (set) DO command [command-parameters]

Walks the directory tree rooted at [drive:]path, executing the FOR
statement in each directory of the tree.  If no directory
specification is specified after /R then the current directory is
assumed.  If set is just a single period (.) character then it
will just enumerate the directory tree.

FOR /L %variable IN (start,step,end) DO command [command-parameters]

The set is a sequence of numbers from start to end, by step amount.
So (1,1,5) would generate the sequence 1 2 3 4 5 and (5,-1,1) would
generate the sequence (5 4 3 2 1)

FOR /F ["options"] %variable IN (file-set) DO command [command-parameters]
FOR /F ["options"] %variable IN ("string") DO command [command-parameters]
FOR /F ["options"] %variable IN ('command') DO command [command-parameters]

or, if usebackq option present:

FOR /F ["options"] %variable IN (file-set) DO command [command-parameters]
FOR /F ["options"] %variable IN ('string') DO command [command-parameters]
FOR /F ["options"] %variable IN (`command`) DO command [command-parameters]

filenameset is one or more file names.  Each file is opened, read
and processed before going on to the next file in filenameset.
Processing consists of reading in the file, breaking it up into
individual lines of text and then parsing each line into zero or
more tokens.  The body of the for loop is then called with the
variable value(s) set to the found token string(s).  By default, /F
passes the first blank separated token from each line of each file.
Blank lines are skipped.  You can override the default parsing
behavior by specifying the optional "options" parameter.  This
is a quoted string which contains one or more keywords to specify
different parsing options.  The keywords are:

    eol=c           - specifies an end of line comment character
                      (just one)
    skip=n          - specifies the number of lines to skip at the
                      beginning of the file.
    delims=xxx      - specifies a delimiter set.  This replaces the
                      default delimiter set of space and tab.
    tokens=x,y,m-n  - specifies which tokens from each line are to
                      be passed to the for body for each iteration.
                      This will cause additional variable names to
                      be allocated.  The m-n form is a range,
                      specifying the mth through the nth tokens.  If
                      the last character in the tokens= string is an
                      asterisk, then an additional variable is
                      allocated and receives the remaining text on
                      the line after the last token parsed.
    usebackq        - specifies that the new semantics are in force,
                      where a back quoted string is executed as a
                      command and a single quoted string is a
                      literal string command and allows the use of
                      double quotes to quote file names in
                      filenameset.

Some examples might help:

would parse each line in myfile.txt, ignoring lines that begin with
a semicolon, passing the 2nd and 3rd token from each line to the for
body, with tokens delimited by commas and/or spaces.  Notice the for
body statements reference %i to get the 2nd token, %j to get the
3rd token, and %k to get all remaining tokens after the 3rd.  For
file names that contain spaces, you need to quote the filenames with
double quotes.  In order to use double quotes in this manner, you also
need to use the usebackq option, otherwise the double quotes will be
interpreted as defining a literal string to parse.

%i is explicitly declared in the for statement and the %j and %k
are implicitly declared via the tokens= option.  You can specify up
to 26 tokens via the tokens= line, provided it does not cause an
attempt to declare a variable higher than the letter 'z' or 'Z'.
Remember, FOR variables are single-letter, case sensitive, global, 
and you can't have more than 52 total active at any one time.

You can also use the FOR /F parsing logic on an immediate string, by
making the filenameset between the parenthesis a quoted string,
using single quote characters.  It will be treated as a single line
of input from a file and parsed.

Finally, you can use the FOR /F command to parse the output of a
command.  You do this by making the filenameset between the
parenthesis a back quoted string.  It will be treated as a command
line, which is passed to a child CMD.EXE and the output is captured
into memory and parsed as if it was a file.  So the following
example:

  FOR /F "usebackq delims==" %i IN (`set`) DO @echo %i

would enumerate the environment variable names in the current
environment.

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only
%~dp$PATH:I - searches the directories listed in the PATH
               environment variable for %I and expands to the
               drive letter and path of the first one found.
%~ftzaI     - expands %I to a DIR like output line
