Problem with redirecting output

Mar

Output redirections from piped command don't seem to work. While in CMD the follwing works fine, but in TCC/LE it just hangs:

Code:
@echo off
REM Check Windows Version
ver | findstr /i "5\.0\." >nul
IF %ERRORLEVEL% EQU 0 goto ver_2000
ver | findstr /i "5\.1\." >nul
IF %ERRORLEVEL% EQU 0 goto ver_XP
ver | findstr /i "5\.2\." >nul
IF %ERRORLEVEL% EQU 0 goto ver_2003
ver | findstr /i "6\.0\." >nul
IF %ERRORLEVEL% EQU 0 goto ver_Vista
ver | findstr /i "6\.1\." >nul
IF %ERRORLEVEL% EQU 0 goto ver_Win7
goto :warn_and_exit

What can I do about this?

Thanks.

It works here. By "works" I mean that it doesn't hang, it displays an error message about a missing label, which is reasonable because the label doesn't exist.

(This seems like an awfully cumbersome way to test versions, by the way. It would be a whole lot simpler to check the value returned by %_WINVER.)

You might post the contents of your TCSTART.BTM file, if you have one. Possibly it's doing something in the pipe shell which the redirection prevents you from seeing.

Yes, I have a TCSTART.CMD and quite a lot of customisations in TCMD.INI, and I tried removing them, to eliminate the problem, after seeing that the script worked fine on another machine.

It turns out that the same TCC/LE directory installation will work on any other machine (same OS), but not this one.

I cannot figure out what is causing this, but at least this is not a permanent problem. Thanks for your help.
 
FWIW I have had the following lines of code at the start of my 4START/TCSTART/4EXIT/TCEXIT, dating back many years (April 2000), to mitigate issues with piping:

Code:
REM Check to see if we're running in a transient shell or a pipe
IFF %_TRANSIENT == 1 .OR. %_PIPE == 1 THEN
  ECHO %@NAME[%_BATCHNAME] - processing short-circuited for transient shell
  QUIT
ENDIFF

Obviously the ECHO is unnecessary, but it can help with debugging.
