for loop parsing problem in XP

[taripo]

I am getting this strange output. (OS is XP as mentioned in title)

I am trying to use this command to grab an IP address that is 10.0.0.5

Primarly to test piping to the FOR command. Hence i'm piping to it and using 'more' in the (..)


But it is not getting the 10 part of the IP.

Any idea what is happening here?

What is going wrong?

Code: Select all

C:\>ipconfig | findstr "Address" | for /f "tokens=13" %f in ('more') do @echo %f

.

C:\>ipconfig | findstr "Address" | for /f "tokens=14" %f in ('more') do @echo %f

:

C:\>ipconfig | findstr "Address" | for /f "tokens=15" %f in ('more') do @echo %f

 0.0.0.5

C:\>ipconfig | findstr "Address" | for /f "tokens=15" %f in ('more') do @echo %f
 >c:\blah\p.p

C:\>type c:\blah\p.p
  .0.0.5

This works

Code: Select all

C:\>for /f "tokens=15" %f in ('ipconfig ^| findstr "Address"') do @echo %f
10.0.0.5

C:\>

But I want to do it via the piping method, hence with 'more' in the round brackets

It's not a reliable technique by the look of it: this is what I get:

d:\abc>ipconfig | findstr "Address" | for /f "tokens=13" %f in ('more') do @echo %f
:
:

d:\abc>ipconfig | findstr "Address" | for /f "tokens=14" %f in ('more') do @echo %f
192.168.0.10
192.168.56.1

d:\abc>ipconfig | findstr "Address" | for /f "tokens=15" %f in ('more') do @echo %f

well, looks like it works for you but not for me

I don't know why yours isn't token=15

In XP it's surely token=15

Code: Select all

C:\>ipconfig | find "Address"
        IP Address. . . . . . . . . . . . : 10.0.0.5

C:\>

first token is IP
second token is Address.
the 13th token is the last dot.
14th token is colon
15th is IP

though mine skips the 1 of 10. for some reason

In Win7 it's the 14th token.
IPv4 Address. . . . . . . . . . . : 192.168.56.1

The For works in Win7. Maybe you tested it in Win7?

My issue is with the For in XP

I'm sorry Taripo, your question didn't include the OS so I wasn't aware of that.

I can't speak for anyone else but I seldom read subject lines and expect the pertinent details to be in the question. That was my mistake.

This is what I get in Windows XP Pro.

c:\>ipconfig | findstr "Address" | for /f "tokens=13" %f in ('more') do @echo %f
.

c:\>ipconfig | findstr "Address" | for /f "tokens=14" %f in ('more') do @echo %f
:

c:\>ipconfig | findstr "Address" | for /f "tokens=15" %f in ('more') do @echo %f
92.168.0.12

Piping into a for loop has been discussed before and with the limitations discussed.

[taripo]

I suppose I could put XP in the body of the question rather than the title. I've just amended the body to mention XP too.

You write that "Piping into a for loop has been discussed before and with the limitations discussed"

It would be useful if you knew Where that was e.g. a link to the thread

It'd be good to know exactly what those limitations are and what is happening there that causes it to eat the number 1

Why not this way?

Code: Select all

ipconfig | findstr "Address" | for /f "tokens=2 delims=:" %f in ('more') do @echo %f

XP

Code: Select all

C:\Documents and Settings\XPMUser>ipconfig | findstr "Address" | for /f "tokens=2 delims=:" %f in ('more') do @echo %f
 192.168.131.65

7

Code: Select all

C:\>ipconfig | findstr "Address" | for /f "tokens=2 delims=:" %f in ('more') do @echo %f
 10.28.16.58

Also, why do you use MORE command? The "natural" way to do that is this:

Code: Select all

for /f "tokens=2 delims=:" %f in ('ipconfig ^| findstr "Address"') do @echo %f

If you don't like to type the "^|" part, you may use this form:

Code: Select all

ipconfig | for /f "tokens=2 delims=:" %f in ('findstr "Address"') do @echo %f
