Batch file: <part of command line> was unexpected at this time

Question

Trying to execute a command inside a batch file and drop the result into a variable.

Here's what I would execute interactively:

curl -d "username=someUser" http://someServer/trusted

The result is a 15-20 character alpha-numeric string.

Here's my attempt at doing same in a batch file:

FOR /f %AA IN('curl -d \"username=someUser\" http://someServer/trusted') DO ECHO %AA

Error returned is:

//someServer/Trusted') was unexpected at this time

I thought I was dealing with some sort of escaping issue, so I added the \ symbols in front of my quotes. From what I've read, the : symobol in http doesn't need to be escaped, but it's interesting to me that's where the failure appears to "start".

Any ideas on this? I'm on Win8.1, FYI

Answer 1

1. for-variables have one-char-variables (%A instead of %AA)
2. you missed a space between IN and (
3. in a batch-file you have to double the percent-signs for the for-variable (%%A instead of %A)
