How to assign variables from text file in for loop of windows batch

Question

@echo off
for /f "delims=" %%i in (servers.txt) do (
set server=%%i
echo server is %server%
)

Here it is unable to set value from text file to variable server.

Answer 1

It is setting the value. You are just not using it correctly. You need to use Delayed Expansion when you are inside a code block.

@echo off
setlocal enabledelayedexpansion
for /f "delims=" %%i in (servers.txt) do (
    set server=%%i
    echo server is !server! 
)
