Windows batch script - string parsing
HI,
I'm writing a windows batch script (.bat).
I have the following string:
"\item1\item2\item3\" - the number of items may change. The string is enclosed with \ as in the example.
I want to retrieve the last item, how do I do that?
Thanks,
Nivo

I wouldn't be here asking for help if I could use any script language I want.
It must be .bat.
It must be .bat.

it's a good idea to switch the / to newline, but how??

GOT IT!!
Your answer gave me an idea.
tokens=1* means that %%b gets all the string except the first token, so using goto I parse each time the remaining until the string is empty, leaving me with the last token.

SET string=a\b\c\d\nivo
:BB
set current=%string%
FOR /F "tokens=1* delims==\" %%a IN ("%string%") DO (
SET string=%%b
)
if NOT "%string%"=="" (goto BB)
@echo %current%

Nice one nivo and Thanks.
But I am just curious why you need it in a bat ^_^

I'm a developer, working on a product that runs on Windows.
I have a small task that we don't want write in C/Java since it involves many system calls that are easy for a batch.
The way we run the product today, customers don't need any scripting tool or 3rd parties (execpt of course Java which is very common and obvious), just Windows OS.
We don't want to change that because of a small, not so very important, feature.
Thanks again,

Consider using python or perl?
