I would like to replace certain part of IP Address in a batch file.
Lets say there is a variable
set ip=10.20.45.254
or
set ip=10.20.45.2
and i have to change the last part to 1 like
10.20.45.254 -> 10.20.45.1
I have tried to check this manual http://ss64.com/nt/syntax-replace.html but I am not sure how to detect exactly the last part of IP because it can have different length...
Is it possible todo?
Try this in batch (replace test.txt with your file name)
for /F "tokens=1,2,3,4 delims=." %%a in (test.txt) do (echo %%a.%%b.%%c.1)
P.S. Try this...
rem -----------------------------------------
rem Imagine that %line has some IP string...
SET _IP=%line:~4%
ECHO IP: %_IP%
rem -----------------------------------------
timeout /t 2
for /f "tokens=1,2,3,4 delims=." %%a IN ("%_IP%") DO (
set gate=%%a.%%b.%%c.1
)
ECHO Gateway IP: %gate%
Take care of the qoutes, they are essential ("%_IP%").
for /? shows you how to: ... in ("%var%") do ...for to treat it as text, not as a filename.SET _IP="12.45.2.123" for /f "tokens=1,2,3,4 delims=." %%a IN (%_IP%) DO echo %%a.%%b.%%c.1 pause then it works fine. But when i do the same from more complex batch file it gives message that it cannot find the file and display IP consuming from %_IP%set ip=10.20.45.254, in your comment you SET _IP="12.45.2.123"Simpler:
set ip=10.20.45.254
for %%a in (%ip%) do echo %%~Na.1
This method works also if the IP's are stored as lines inside a file:
for /F %%a in (ipList.txt) do echo %%~Na.1
You can use this to enter in an IP address that you want with a subnet mask of 255.255.255.0.
@echo off
echo "Enter Static IP"
echo "Static IP Address:"
set /p IP_Addr=
netsh interface ip set address <Name of Network Adapter> static %IP_Addr% 255.255.255.0
You can always add in a section to ask for subnet, or just hard code it.
