Clearcase find 命令与 Tcl 脚本和批处理文件结合使用：重定向不起作用

又是我；-)

我尝试从批处理文件启动cleartool find 命令。该批处理文件从 Tcl 脚本获取参数。

批处理文件：

 SET VERARG="version(\main\LATEST) && !lbtype(%3)"
 cleartool find . -version %VERARG% -print > Y:\x\Logs\%3.log

Tcl 脚本：

 set v_cmd "y:\\x\\clearcase_find_change.cmd $v_drive $v_path $v_label \n"
 set v_outp [exec cmd << $v_cmd]

当我从命令行启动批处理文件时，它可以工作并将命中写入日志文件，但是当我从 Tcl 启动它时，我在命令窗口中看到命中，但它只创建没有内容的日志文件。我已经使用一个非常简单的批处理文件对其进行了测试，该文件仅包含 echo 命令和重定向。这很有效，我也尝试过使用不同的驱动器，但没有成功。我还检查了批处理文件收到的参数，但对我来说一切看起来都很好。

简单的调用，有效：

Batch: echo %1 > Y:\x\%2.log
Tcl: set v_cmd "y:\\x\\simple_echo.cmd $v_lib $v_label \n"

it's me again ;-)

I try to start the cleartool find command from a batch file. That batch files gets his arguments from a Tcl script.

Batch File:

 SET VERARG="version(\main\LATEST) && !lbtype(%3)"
 cleartool find . -version %VERARG% -print > Y:\x\Logs\%3.log

Tcl Script:

 set v_cmd "y:\\x\\clearcase_find_change.cmd $v_drive $v_path $v_label \n"
 set v_outp [exec cmd << $v_cmd]

When I start the batch file from command line, it works and it wrotes the hits to the log-file, but when I start it from Tcl, I see the hits in the command window, but it only creates the log-files with no content. I tested it already with a very simple batch file, which only contents a echo command and a redirection. That worked, I've also tried to use different drives, but with no success. I checked also the received arguments of the batch-file, but everything looked fine to me.

Simple Call, which worked:

Batch: echo %1 > Y:\x\%2.log
Tcl: set v_cmd "y:\\x\\simple_echo.cmd $v_lib $v_label \n"

也许缺少一个 cmd 指令来指定 DOS 会话应执行然后退出：

set v_outp [exec cmd << $v_cmd /c]

或：

set v_outp [exec cmd /c << $v_cmd]

或：（

set v_cmd "/c y:\\x\\clearcase_find_change.cmd $v_drive $v_path $v_label \n"
set v_outp [exec cmd << $v_cmd]

以确保首先传递 /c）

请参阅 < a href="http://www.faqs.org/faqs/tcl-faq/tk/windows/" rel="nofollow">Tcl/Tk 常见问题解答：

exec cmd.exe >&@stdout <@stdin /c dir

将对当前目录执行目录命令。
查看 Windows 帮助，了解 cmd.exe 下可用的开关。
“/c”告诉它执行命令然后退出。 “/k”告诉它执行命令并保持 DOS 命令解释器处于活动状态。
（请注意，cmd.exe 是 Windows NT 上 MS-DOS 解释器的名称。）

Maybe it is missing a cmd directive to specify that the DOS session should execute and then quit:

set v_outp [exec cmd << $v_cmd /c]

or:

set v_outp [exec cmd /c << $v_cmd]

or:

set v_cmd "/c y:\\x\\clearcase_find_change.cmd $v_drive $v_path $v_label \n"
set v_outp [exec cmd << $v_cmd]

(to make sure the /c is passed first)

See Tcl/Tk FAQ:

exec cmd.exe >&@stdout <@stdin /c dir

will do the directory command for the current directory.
Check out the Windows help for the switches available under cmd.exe.
"/c" tells it to execute the command and then exit. "/k" tells it to execute the command and keep the DOS command interpreter active.
(Note that cmd.exe is the name of the MS-DOS interpreter on Windows NT.)
