Rename several files to remove characters

I'v got several directories that need the file names to all be the same, so I need to remove the part that makes them distinct.

For example I need to rename in directory 'abc' the file '' to 'access.20051227.gz'

and in directory 'xyz' rename the file '' to 'access.20051227.gz'

PROVIDED all the files are in that format, then use this single command line:

FOR /f "tokens=1,2,3,4 delims=." %a in ('dir /a-d /b') do echo ren "%a.%b.%c.%d" "%a.%c.%d"

NOTE: this will DISPLAY the command line executed for each file in the directory.  If you are satisfied this is going to do what you want it to, remove the echo from the line above.

Thank you for the quick answer, it worked great. Only one thing, this is something I need to run nightly on the same directories. So I noticed if you run it once it works great, but when I use it a 2nd time it eliminates needed characters.

For example it renames 'access.20051227.gz' to 'access.gz' and so on.

If it's easier to hardcode the abc or xyz from my examples, I can do that because the format is consistent.

If "" and "" NEVER change, then I'd suggest this:

FOR /f "tokens=1,2,3,4 delims=." %a in ('dir /a-d /b*') do echo ren "%a.%b.%c.%d" "%a.%c.%d"

OK, that worked great. One last (probably dumb) question.

When I put it in a batch file it errors

'C:\test>"FOR /f "tokens=1,2,3,4 delims=." a.c.a.d""
The system cannot find the path specified.'

But it works fine straight from the command line. What syntax do I use in a bat file?
