Hi, Joakem

The for command execute the commands between the two ( ) and any output will be assigned to a variable %%a or whatever charachter you put there.

So the command

Code: Select all

IPCONFIG ^| find "IPv4"

It has two commands, the first is "IPCONFIG", If you execute that in the command line you will get somthing like that

Windows IP Configuration


Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 50.1.1.15
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.10.10.10

and this code " ^|" redirect that out put to the command "Find" that search for the word "IPv4" in the previout output.

so if you use this command in the cmd window

Code: Select all

IPCONFIG |find "IPv4"

it should give you the whole line that contain the word "IPv4"

Note, when i run that code it give me nothing, casue as you see in the out put, there is no words like "IPv4"
but if i change that word to "IP" it will give me two lines that has the word "IP".

Windows IP Configuration
IP Address. . . . . . . . . . . . : 50.1.1.15

BUt note that the for loop uses a delimt which is : so the out put for the for loop in a command line should give you just the IP "50.1.1.15" not the whole two lines.
