Set your Path environment variable in Windows to facilitate compiling and running Java programs fm the command line: 1. Open My Computer, and browse to the place where your Java JDK binary files live. (something like C:\Program Files\Java\jdk1.6.0_01\bin). Select the pathname at the top of the window, and type ctrl‐C to copy that path to your clipboard. 2. Log in to an account with administrative rights (localmgr). 3. Right‐click "My Computer", and choose Properties. Click the Advanced Tab. 4. Click Environment Variables 5. In the System Variables List, scroll down to find Path. Select it, then then click Edit. 6. At this point you want to be careful not to lose what is there. (Single)click in the Variable vaslue field, then press the End key on your keyboard. 7. Now use the left arrow key to slowly scroll through the long string, looking for the same pathname as the one that you copied to your clipboard. If it is there, you don't need to do anything. Repeatedly click Cancel to exit all of the dialog boxes. 8. If you don't find it, press the End key again. Type a semicolon (;), and then Ctrl‐v to paste in that pathname. Press OK repeatedly to Exit the properties dialogs. 9. Check it out. Press the Start button and choose Run (a shortcut for this is to hold down the Windows key and press R). Type cmd and press Enter. At the DOS prompt, type javac and press Enter. If you get the 'javac' is not recognized as an internal or external command, operable program or batch file error, something is wrong. If you get a list of options for the java compiler, everything should be okay.! .

Command Line Interface Specification Windows
Command Line Interface Specification Windows Online Backup Client version 4.3.x 1. Introduction The CloudBackup Command Line Interface (CLI for short) makes it possible to access the CloudBackup Client software from the command line. The following actions are implemented: backup, delete, dir en restore. These actions are described in more detail in the following paragraphs. For all actions applies that a successful action is indicated by means of exit code 0. In all other cases a status code of 1 will be used. 2. Configuration The command line client needs a configuration file. This configuration file may have the same layout as the configuration file for the full CloudBackup client. This configuration file is expected to reside in one of the following folders: CLI installation location or the settings folder in the CLI installation location. The name of the configuration file must be: Settings.xml. Example: if the CLI is installed in C:\Windows\MyBackup\, the configuration file may be in one of the two following locations: C:\Windows\MyBackup\Settings.xml C:\Windows\MyBackup\Settings\Settings.xml If both are present, the first form has precedence. Also the customer needs to edit the CloudBackup.Console.exe.config file which is located in the program file directory and edit the following line: 1 <add key="SettingsFolder" value="%settingsfilelocation%" /> After making these changes the customer can use the CLI instruction to make backups and restore data. 2.1 Configuration Error Handling If an error is found in the configuration file, the command line client will issue an error message describing which value or setting or option is causing the error and terminate with an exit value of 1.

Linux-PATH.Pdf
http://www.linfo.org/path_env_var.html PATH Definition PATH is an environmental variable in Linux and other Unix-like operating systems that tells the shell which directories to search for executable files (i.e., ready-to-run programs ) in response to commands issued by a user. It increases both the convenience and the safety of such operating systems and is widely considered to be the single most important environmental variable. Environmental variables are a class of variables (i.e., items whose values can be changed) that tell the shell how to behave as the user works at the command line (i.e., in a text-only mode) or with shell scripts (i.e., short programs written in a shell programming language). A shell is a program that provides the traditional, text-only user interface for Unix-like operating systems; its primary function is to read commands that are typed in at the command line and then execute (i.e., run) them. PATH (which is written with all upper case letters) should not be confused with the term path (lower case letters). The latter is a file's or directory's address on a filesystem (i.e., the hierarchy of directories and files that is used to organize information stored on a computer ). A relative path is an address relative to the current directory (i.e., the directory in which a user is currently working). An absolute path (also called a full path ) is an address relative to the root directory (i.e., the directory at the very top of the filesystem and which contains all other directories and files).

Explain the function and use of replaceable parameters in batch files. 6. Explain the function of pipes, filters, and redirection in batch files. STUDENT OUTCOMES 1. Use Edit to write batch files. 2. Use COPY CON to write batch files. 3. Write and execute a simple batch file. 4. Write a batch file to load an application program. 5. Use the REM, PAUSE, and ECHO commands in batch files. 6. Terminate a batch file while it is executing. 7. Write batch files using replaceable parameters. 8. Write a batch file using pipes, filters, and redirection. CHAPTER SUMMARY 1. Batch processing means running a series of instructions without interruption. 2. Interactive processing allows the user to interface directly with the computer and update records immediately. 3. Batch files allow a user to put together a string of commands and execute them with one command. 4. Batch files must have the .BAT or .CMD file extension. 5. Windows looks first internally for a command, then for a .COM files extension, then for a .EXE file extension, and finally for a .BAT or .CMD file extension. 6. Edit is a full-screen text editor used to write batch files. 7. A word processor, if it has a means to save files in ASCII, can be used to write batch files.

Starting a Batch File Example
LA Solutions ShellBatch.doc Starting a Batch File from MicroStation There have been a couple of questions in the MicroStation newsgroups along the lines of “How do I start an operating system batch file without leaving MicroStation?” One answer to the question is to use Visual Basic for Applications (VBA), which is part and parcel of MicroStation V8. VBA provides extensive functionality, which you can extend by referencing built-in Visual Basic (VB) methods, and even by calling the Win32 native application programming interface (API) directly. VB provides a Shell() method, which means ‘attempt to start whatever executable program I give you’. A batch file (having a .bat extension) is not an executable file. The way to ‘execute’a batch file is to give its path to the Windows built-in command executable cmd.exe. The way to persuade the operating system to do something with a batch file is to put these ideas together like this… Shell(“cmd.exe /k batchfile.bat”) Unfortunately, things aren’t always as simple as we would like, because Shell() can’t itself divine the location of the executable file. The VBA project ShellBatch.mvba takes care of these details, and all you have to know is how to start it. 1. Copy ShellBatch.mvba to one of the folders in your computer’s VBA search path (MS_VBASEARCHDIRECTORIES). C:\Program Files\Bentley\Workspace\Standards\VBA is a good choice 2. Open MicroStation’s key-in window from the Utilities menu 3. Start your batch file with the following key-in: you must know the full path to the file: vba run [ShellBatch].Module1.Main <batch file path> For example: vba run [ShellBatch]Module1.Main D:\temp\test.bat Copyright © LA Solutions 2003…2005 visit http://www.la-solutions.co.uk.
