Remove whitespace/trailing

Question

I'm executing the following command to write the current IPv4 address to a logfile:

ipconfig | findstr IPv4>>"c:\ip.log"

However, there are some whitespaces, how can I remove those?:

   IPv4 Address. . . . . . . . . . . : 10.0.0.15
   IPv4 Address. . . . . . . . . . . : 172.16.0.15
   IPv4 Address. . . . . . . . . . . : 192.168.0.15

Thanks.

@ECHO OFF
SETLOCAL

FOR /f "tokens=1*delims=:" %%a IN ('ipconfig^|findstr "IPv4" ') DO (
 FOR /f %%c IN ("%%b") DO ECHO ++%%c++
)

GOTO :EOF

Naturally, the echo could be a set if you so desire. The ++ either end of the data is merely to show that the spaces have been removed.

Find the target line(s) from an ipconfig command, select that part beyond the : on those lines, and process the resultant string, removing ant spaces (default delimiters in the for /f %%c)

This is a nice command you could use: http://fart-it.sourceforge.net/ You would use it to find and replace the part that is waste for your purpose.

Edit If you want stick with the commands available, then i think you would best use this: How to replace substrings in windows batch file

Look at Andriy M's first answer.

thanks dannl, but I'd prefer to use commands default to Windows only and not any external tools. – zach Feb 25 '15 at 16:14

Maybe use ECHO and FOR to try something like this:

        ipconfig | findstr IPv4>>"c:\ip.log"
        < "c:\ip.log" SET /P my_first_ip=
        FOR /F "delims= tokens=2" %%I IN ("%my_first_ip%") DO (
        ECHO %%I>"c:\ip.log"
        )

PowerShell:

get-wmiobject Win32_NetworkAdapterConfiguration -filter 'IPEnabled=TRUE' |
  select-object -expandproperty IPAddress | out-file "C:\IP.log" -append
