copy - Batch: Checking if a file is locked does not work -

i wrote following batch following steps:

• check if file on server opened user
• make backup of file
• open file

2>nul ( >>test.xlsx (call )) if %errorlevel% == 1 goto end  @echo off rem date, make if file name friendly /f "tokens=1-4 delims=/ " %%i in ('date/t') set d=%%j-%%k-%%l@%%i@ rem time, make if file name friendly /f "tokens=1-9 delims=:. " %%i in ('time/t') set t=%%i_%%j_%%k%%l  set xlsx=%d%%t%.xlsx ren test.xlsx %xlsx% xcopy *.xlsx j:\test\backup  ren %xlsx% test.xlsx  call test.xlsx  :end 

the problem is, line wich tries check if file locked not work on server.

can me find mistake in batch?

if write

2>nul ( >>test.xlsx (call )) if %errorlevel% == 1 goto end 

you error. if not expected. 2 instructions in same line without separation.

if converted

2>nul ( >>test.xlsx (call )) & if %errorlevel% == 1 goto end 

then problem delayed expansion. %errorlevel% variable replaced value when line parsed , @ time, first part of has not been executed, no errorlevel set.

if change

2>nul ( >>test.xlsx (call ))  if %errorlevel% == 1 goto end 

it work

for more concise construct, can try this

(>>test.xlsx call;) 2>nul || goto end 

same function, less code.
