windows batch file tips

아래 몇가지만 알아서 윈도에서 자주쓰는 batch file을 만들자

1. Input 받아 command에 넣기
2. input validate하기
3. file/folder 있는지 확인후 만들기, 없으면 에러나 만들기
4. if else 
5. for loop
6. 외부 프로그램 실행 = start
7. input받아 실행하기
8. 현재날짜 format대로 출력
9. 현재 dir 얻기, 이전 cur path로 돌아가기
10. sleep, timeout
11. 외부파일에서 parameter 순차적으로 읽기
12. 환경variable에서 읽기, PATH나 user variable like msm
13. 오늘날짜 구하기

1. Input이 없을때 나가기, 처음 3개 character비교하기

rem argument check, no arument exit
if -%1-==-- echo Argument one not provided & exit /b

rem user input, %1, %2 and so on

set a=%1
rem set a=abcd
echo %a:~0,3%
if %a:~0,3%==COM echo same

if exist file.txt (
	echo The file exists.
) else (
	echo The file does not exist.
)

rem directory check
if exist temp (
	echo The temp exists.
) else (
	echo The temp does not exist.
)

rem if directory is not available, create it
if not exist temp mkdir temp

goto :mylabel
echo Hello 1
REM Hello 1 never gets printed.
 
:mylabel
echo Hello 2
goto :eof

rem robocopy, xcopy, copy
sleep 5
rem timeout
timeout /t 5

set arg1=%1
set iteration=1
set num=1

rem note: it end with \, %mypath:~0,-1% will remove \

if exist log_path(
	echo Logs folder exists already.

	mkdir log_path    
	echo Logs Folder created!
)

:loop
adb root

3. input path 받아 fastboot flash 하기

@echo off
rem -------------------------------
rem Fred Oh (email) 
rem 2015 01 01 starting new life
rem -------------------------------
setlocal enabledelayedexpansion
for %%i in (1) do (
  set /p c=enter a build location? 
  echo waiting for device
  echo Flashing boot image  
  fastboot.exe flash boot !c!\boot.img
  echo Flashing userdata image
  fastboot.exe flash userdata !c!\userdata.img
  echo Flashing system image
  fastboot.exe flash system !c!\system.img
  echo Flashing recovery image
  fastboot.exe flash recovery !c!\recovery.img
  echo Flash completed, rebooting device
  fastboot.exe continue
  sleep 3
)

4. function 예제

@echo off
rem -------------------------------
rem Fred Oh (email) 
rem 2015 01 01 starting new life
rem -------------------------------
@echo off
call :power %1 %2
echo %result%
rem Prints 16, determined as 2 * 2 * 2 * 2
goto :eof

rem __Function power______________________
rem Arguments: %1 and %2
:power
setlocal
set counter=%2
set interim_product=%1
:power_loop
if %counter% gtr 1 (
  set /A interim_product = %interim_product% * %1
  set /A counter = %counter% - 1
  goto :power_loop
)
endlocal & set result=%interim_product%
goto :eof

5. 간단한 fastboot flash 처리예제, environment variable 읽어서 처리하기. msm is Env variable

@echo off
rem -------------------------------
rem Fred Oh (email) 
rem 2015 01 01 starting new life
rem -------------------------------

if -%msm%- == -- (
	echo no msm defined, set msm8992
	set msm=msm8992
)
set out=out\target\product\%msm%

rem if no parameter
rem 		check current directory then $OUT directory
if -%1-==-- ( 
echo Argument one not provided, Assume current directory
call :function_fastboot
echo IMG flashed done
goto :eof
) 

rem if parameter(PATH) are given
rem 		check network path or local path
set in_path=%1
echo %in_path:~0,2%
if %in_path:~0,2%==\\ (
	echo Network path, pushd %in_path% and will do popd later
	pushd %in_path%
	call :function_fastboot
	popd
) else (
	echo LOCAL path found CD %in_path%
	cd %in_path%
	call :function_fastboot
)
goto :eof

rem ________________________
rem FUNCTION flash FASTBOOT
rem --------------------------------------------

:function_fastboot
setlocal
if exist system.img (
	echo current directory has IMG files
	fastboot flash aboot 		emmc_appsboot.mbn
	fastboot flash boot 		boot.img
	fastboot flash cache 		cache.img
	fastboot flash persist 		persist.img
	fastboot flash recovery 	recovery.img
	fastboot flash userdata 	userdata.img
	fastboot flash system 	system.img
) else (
	if exist %out%\system.img (
		echo IMG found in %out%
		fastboot flash aboot 		%out%\emmc_appsboot.mbn
		fastboot flash boot 		%out%\boot.img
		fastboot flash cache 		%out%\cache.img
		fastboot flash persist	 	%out%\persist.img
		fastboot flash recovery 	%out%\recovery.img
		fastboot flash userdata 	%out%\userdata.img
		fastboot flash system 	%out%\system.img
	) else (
		echo no IMG file found!!!! EXIT.
		exit /b
	)
)
endlocal
goto :eof
