As part of a task that I am working on for a customer, I need to make some modifications to the enterprise logon script. Windows command-line is definitely not my area of expertise, but I am doing OK with most of it. However, I am running into the following inconsistent behavior, that I cannot figure out.
The following commands:
Set TMP= For /f "tokens=1,2,3 delims=:" %A in ('ipconfig ^| Find "Default Gateway" ^| Findstr/N "."') do (If not defined TMP Set TMP=%~C)
When executed at the command prompt (a windows 7 CMD.EXE window), work as expected and TMP gets set with the IP address of my default gateway. However, if I execute the exact same commands from a CMD file, in the same window, it fails with the following output (Echo On):
>Set TMP= ~C) was unexpected at this time. >For /f "tokens=1,2,3 delims=:" ~C)
I have tried both CALL and running the script directly. I have tried it both with and without
usebackq, and with and without the parenthesis after the
DO, with the same results every time: it works interactively, but not from a script in the same session.
What the heck is going on here and how can I fix it?
