What Is "for" Loop Parameter?

A

A "for" loop parameter is a parameter defined in a "for" command to represent each item from a give list.

A "for" loop parameter must be defined using the "%%name" format, where "name" can be any identifier string.

Same parameter modifiers as batch parameters are also supported on "for" loop parameters as listed below for "%%p":

%%~p         - expands %%p removing any surrounding quotes (")
%%~fp        - expands %%p to a fully qualified path name
%%~dp        - expands %%p to a drive letter only
%%~pp        - expands %%p to a path only
%%~np        - expands %%p to a file name only
%%~xp        - expands %%p to a file extension only
%%~sp        - expanded path contains short names only
%%~ap        - expands %%p to file attributes
%%~tp        - expands %%p to date/time of file
%%~zp        - expands %%p to size of file
%%~$PATH:p   - searches the directories listed in the PATH
               environment variable and expands %%p 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

You can also apply multiple modifiers together as shown below. The order of modifier locations is not important.

%%~dpp       - expands %%p to a drive letter and path only
%%~nxp       - expands %%p to a file name and extension only
%%~dp$PATH:p - searches the directories listed in the PATH
               environment variable for %%p and expands to the
               drive letter and path of the first one found.
%%~ftzap     - expands %%p to a DIR like output line

Of course, those modifiers are mostly applicable to "for" loop parameters that represent file names.
