The `for` command is a relatively complex command - China DOS Union Forum

The building-block mentioned that "In addition, the replacement of FOR variable references has been enhanced. You can now use the following option syntax:

~I - Remove any quotes (") and expand %I

%~fI - Expand %I to a fully qualified pathname

%~dI - Expand %I to just a drive letter

%~pI - Expand %I to just a path

%~nI - Expand %I to just a file name

%~xI - Expand %I to just a file extension

%~sI - The expanded path contains only short names

%~aI - Expand %I to the file attributes of the file

%~tI - Expand %I to the date/time of the file

%~zI - Expand %I to the size of the file

%~$PATH:I - Find the directories listed in the path environment variable and expand %I to the first fully qualified name found. If the environment variable is not defined or the file is not found, this combination expands to an empty string. Modifiers can be combined to get multiple results:

%~dpI - Expand %I to just a drive letter and path

%~nxI - Expand %I to just a file name and extension

%~fsI - Expand %I to a full pathname with short names

%~dp$PATH:i - Find the directories listed in the path environment variable and expand %I to the first drive letter and path found.

%~ftzaI - Expand %I to a DIR.....like output line"

How are things like "%~fI" applied specifically? Can you give a simple example to illustrate? Also, I don't quite understand this sentence: "FOR /F "eol=; tokens=2,3* delims=, " %i in (myfile.txt) do command will analyze each line in myfile.txt, ignore those lines starting with a semicolon, pass the second and third tokens of each line to the for program body; delimited by commas and/or spaces." Among them, which parameter "ignores" "ignore those lines starting with a semicolon"? What are the functions of "eol=;" and delims=,?
Please the building-block or各位 experts explain~~~

Well, let's just give it a try. I think it should be easier to understand, hehe! Thanks, forum moderator!

There are still many places I don't understand, I'll digest it slowly
