batch-file For Loops in Batch Files Looping through each line in a files set
Example
The following will echo each line in the file C:\scripts\testFile.txt. Blank lines will not be processed.
for /F "tokens=*" %%A in (C:\scripts\testFile.txt) do (
echo %%A
rem do other stuff here
)
More advanced example shows, how derived in FOR loop from a restricted files set data can be used to redirect batch execution, while saving the searched content to a file:
@echo off
setlocal enabledelayedexpansion
for /f %%i in ('dir "%temp%\test*.log" /o:-d /t:w /b') do (
set "last=%temp%\%%i"
type !last! | find /n /i "Completed" >nul 2>&1 >> %temp%\Completed.log ^
&& (echo Found in log %%i & goto :end) || (echo Not found in log %%i & set "result=1"))
:: add user tasks code here
if defined result echo Performing user tasks...
:end
echo All tasks completed
exit /b
Note, how long command strings are split into several code lines, and command groups are separated by parentheses.
