I wrote a batch to check and deploy the rails app from github, the batch file see below. The problem is git.exe fetch origin | find "remote: Counting Objects" always returns errorlevel 1, even when we have new commits. I must terminate the Rails App first, because some files are locked (*.jars) and cause the git pull command to fail.

I search and found below topic, but even using git.exe instead of the git.cmd, the problem still exists.

I try to using a temp file to store git.exe fetch origin result, but if seems this command always print the result to the console.

Also: 

git pull | find "Already up-to-date."
if %errorlevel% == 1 (

Works fine

    REM @echo off
    set path=%path%;C:\Program Files\Git\bin;D:\jruby-1.6.7\bin
    set JRUBY_OPTS=--1.9
    git.exe fetch origin | find "remote: Counting objects"
    if %errorlevel% == 0 taskkill /f /im:jruby.exe
    git pull | find "Already up-to-date."
    if %errorlevel% == 1 (
    REM 
      start cucumber.bat
      REM do something else when update
    )

    REM RAILS
    tasklist | find "jruby.exe"
    if %errorlevel%==1 (
     echo @rails s > rail.bat
     echo @exit >> rail.bat
     start cmd /c rail.bat
    )
    exit

At a guess I'd say it's breaking because the 'Counting objects' line shows a dynamic progress indicator, but don't quote me on that.

...
git fetch origin
git branch -a --no-merged |find "remotes/origin"
if %errorlevel% == 0 taskkill /f /im:jruby.exe
...

You might also want to limit it to just the current branch:

git branch -a --no-merged |find "remotes/origin/mybranch"
