    • Method Detail

      • exec

        public static String exec​(String command)
        Deprecated.

        Executes the given command as if it had been executed from the command line of the host OS (cmd.exe on windows, /bin/sh on *nix) and returns all content sent to standard out as a string. If the command finishes with a non zero return value, a CommandFailedException is thrown.

        Content sent to standard error by the command will be forwarded to standard error for this JVM. If you wish to capture StdErr as well, use buildProcess(String) to create a ProcessStarter and call the ProcessStarter.withStdErrHandler(gw.util.ProcessStarter.OutputHandler) method.

        This method blocks on the execution of the command.

        Example Usages: 

           var currentDir = Shell.exec( "dir" ) // windows
   var currentDir = Shell.exec( "ls" )  // *nix
   Shell.exec( "rm -rf " + directoryToNuke )

        Parameters:
        command - the command to execute
        Returns:
        the content of standard out
        Throws:
        CommandFailedException - if the process finishes with a non-zero return value

        Note: On windows, CMD.EXE will be used to interpret "command" so that commands like "dir" work as expected. This can occasionally cause problems due to limitations of CMD.EXE (e.g. a command string may be too long for it.) In these cases consider using the buildProcess(String)

      • exec

        public static String exec​(String command,
                          String cs)
        Deprecated.

        Executes the given command as if it had been executed from the command line of the host OS (cmd.exe on windows, /bin/sh on *nix) and returns all content sent to standard out as a string. If the command finishes with a non zero return value, a CommandFailedException is thrown.

   var currentDir = Shell.exec( "ls" )  // *nix

        Parameters:
        command - the command to execute
        Returns:
        the content of standard out
        Throws:
        CommandFailedException - if the process finishes with a non-zero return value

      • execWithPipe

        public void execWithPipe​(String command)
        Deprecated.

        Executes the given command as if it had been executed from the command line of the host OS (cmd.exe on windows, /bin/sh on *nix) and pipes all data sent to this processes stdout, stderr, and stdin. If the command finishes with a non zero return value, a CommandFailedException is thrown.

        Stdout and Stderr from the sub-process will be piped to the current process' stdout and stderr. Any input in this processes stdin will be piped to the sub-process' stdin

        Content sent to standard error by the command will be forwarded to standard error for this JVM.

        This method blocks on the execution of the command.

        Example Usages: 

           Shell.exec( "read \"are you there?\"" )

        Parameters:
        command - the command to execute
        Throws:
        CommandFailedException - if the process finishes with a non-zero return value

      • buildProcess

        public static ProcessStarter buildProcess​(String command)
        Deprecated.
        Builds a process starter given a command. Single parameters in the command can be grouped by using double quotes or single quotes. I.e. ls "~/my file with spaces" works as well as ls '~/my file with spaces'.
        Parameters:
        command - the command to create a process starter for
        Returns:
        the process start.

      • readLine

        public static String readLine​(String prompt)
        Deprecated.
        Prints the given prompt and then reads a line from standard in. This can be used for basic user interactions in command line environments. This method uses the JLine library to provide a reasonable line-editing experience for the user. For example, the delete key, arrow keys, and home and end keys work as they would expect, and the prompt is not editable.
        Parameters:
        prompt - the prompt to show the user
        Returns:
        the string entered

      • readMaskedLine

        public static String readMaskedLine​(String prompt)
        Deprecated.
        Prints the given prompt and then reads a line from standard in, but with the input masked with asterisks
        Parameters:
        prompt - the prompt to show the user
        Returns:
        the string entered

      • getAllThreadStacks

        public static String getAllThreadStacks()
        Deprecated.

      • dumpStacks

        public static void dumpStacks()
        Deprecated.
