Re^2: IPC::Run on Windows, path separator

Its invoking the shell

I would not expect that it does. From the perldocs:

       # Launch a sub process directly, no shell.  Can't do redirectio
+n
       # with this form, it's here to behave like system() with an
       # inverted result.
          $r = run "cat a b c" ;

So this example explicitly says no shell.

`system` calls the shell when it's documented not to in Windows. According to the documentation, `perl -e"system('dir')"` and `perl -e"system('foo.bat')"` should fail, yet both work. This might be documented in perlport.	[reply] [d/l] [select]

Please call for the documentation to change, not the implementation. It's a few little details like this that make perl usable on windows.	[reply]

Whatever we think of it, we're stuck with it because of backwards compatibility reasons. Note that `system { $cmd[0] } @cmd;` [download] appears to work as documented, except for the error code.	[reply] [d/l]

Indeed! OTOH, `IPC::Run::run(['echo xxx'])` fails.... -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]

You're giving it a batch file, and only the shell runs batch files, so both the following lines work for me `IPC::Run::run(['C:/perl/5.10.1/bin/MSWin32-x86-multi-thread/perl.EXE', + qw! -e die(666) !]) ; IPC::Run::run(['C:\perl\5.10.1\bin\MSWin32-x86-multi-thread\perl.EXE', + qw! -e die(666) !]) ;` [download]	[reply] [d/l]
