Help to decipher what this is saying

[elwaysgod]

Hi,
Need help converting this logic into english. Can anyone explain it?


*********************************

@echo off

setlocal

echo REM Begin to copy 'App' dir to backup location > %outFile_CopyAppDir%

pushd "%ess_app_dir_source%"

for /f "tokens=*" %%a in ('dir /b /ad 2^>NUL') do call ROCDIR "%%a"

popd

This is a batch script for Windows NT/2K/XP. Nothing to do with vbscript. Is it a puzzle that someone set you? Looks like a random half written script.

@echo off
Do not echo anything

setlocal
begin local environment changes

echo REM Begin to copy 'App' dir to backup location > %outFile_CopyAppDir%
Stick something in the file %outFile_CopyAppDir%

pushd "%ess_app_dir_source%"
save your current directory and cd %ess_app_dir_source%

for /f "tokens=*" %%a in ('dir /b /ad 2^>NUL') do call ROCDIR "%%a"
call procdir on all the directories in 2>NUL. The procdir routine is missing from this script. ^ means do not interpret the next character.

popd
return to the directory you came from

Problem with the script: there should be an endlocal here

Correction 2^> NUL converts to 2> NUL which means "do not display error output"

I'd forgotten that cmd is similar to Unix in that 1> is normal output and 2> is error output
