While path and filename inputs of all Actions of Automation Workshop are handled automatically, Run CMD Command Action requires the use of double quotes. JJM Restricting access to the command interpreter (cmd.exe) itself accomplishes very little in terms of security. MHo Hello all, the exec $::env(ComSpec) is almost always no alternative in real production systems, as the command line is restricted there by policy for normal users. By the way, win explorer should be put in background (add "&") to avoid an error. HaO Great Poor Yorick, works great for me. For example, the Windows FIND command has its own peculiar syntax:Įxec $env(ComSpec) /c " /select,$nativename" Since there is no way to tell exec to skip the step of translating its arguments according to the default _setargv(), other workarounds must be improvised. Still other programs roll their own _setargv(). It can be selected via the appropriate command-line switch at compile time. Since the syntax of the command line for any given program is a moving target, and individual programs can get wild and woolly about parsing the command line, the only sane thing for exec to do is to convert according to the rules of the default _setargv() function, which are documented in in Parsing C Command-Line Arguments, Visual Studio 2013.Īnother _setargv() that is a part of the standard Windows development environment expands wildcard characters, and is described in Expanding Wildcard Arguments, Microsoft Visual Studio 2013. This creates a mismatch with exec, which provides an API compatible with that of the the Unix execve() function, which accepts a sequence of values rather than a single command line.įor Windows, exec must convert its arguments into a single command line. The program can provide its own _setargv(), giving it complete control over what syntax to impose on the command line. Before the Windows system calls main(), it calls _setargv() to parse the command line into the standard C argc and argv arguments that it passes to the main() function of the program. On the Windows platform, a program is executed by passing the entire command line as a single value to the system. The exec quotes problem and the exec ampersand problem are due to the mismatch between the command execution paradigms of exec and Microsoft Windows. Windows cmd: PS C:UserstomProjekteevaluate> & C:UserstomAppData. c++cmdcommand-line-argumentsmatlabprocess.start. Hence there is no way of just using a double quote in a debugging argument. Open windows explorer in the current directory: start. C Process Start needs Arguments with double quotes they disappear. Launch a GUI application: Start applicationįor example, to launch internet explorer, we can use the below command. A new command window will be executing the specified command and the current window will be back to prompt to take the next command. Run a command in the background like we do using ‘&’ in Linux: In Windows, we can do. We just need to provides them in double-quotes by separating them with space. Run the command in the same window: Start /b command. We can run multiple commands with the cmd /c. ![]() ![]() In Windows, we can do similar thing by using start command. For example, to run a batch file in another command window and to close the window after batch file execution completes, the command will be: Start cmd /c C:\mybatchfile.bat. Run a command in the background like we do using ‘&’ in Linux: Run the command in the same window: Start /b command Run a command in another window and terminate after command execution: start cmd /c commandįor example, to run a batch file in another command window and to close the window after batch file execution completes, the command will be: Start cmd /c C:\mybatchfile.bat ![]() Parameter names and their values are separated by spaces on the command line. Launch new command window and run dir command.: Start dir How to correctly use quotes with string values that contain spaces in the. If the command is of a GUI application, the application will be launched with out any new command window. This command opens a new command window and also runs the specified command.
