Getting started with batch-file
From Microsoft Technet:
With batch files, which are also called batch programs or scripts, you can simplify routine or repetitive tasks. A batch file is an unformatted text file that contains one or more commands and has a .bat or .cmd file name extension. When you type the filename at the command prompt, Cmd.exe runs the commands sequentially as they appear in the file.
Batch File Names and Extensions
|.bat||This extension runs with MS-DOS and all versions of Windows|
|.cmd||Used for batch files in Windows NT family|
|.btm||The extension used by 4DOS and 4NT|
To understand the difference between
.bat please see here.
Avoid names which are already the name of built-in commands. like
tracert. There is a utility called
tracert.exe. So, avoid naming a batch file
Running Batch File
The easiest way to run a batch file is simply double-clicking its icon. Or paste the file full path into a command prompt, or just its name if command Prompt was started from the batch file directory, then enter.
Editing and Viewing Batch Files
Any ASCII editor can edit batch files. A list of editors that can syntax highlight batch syntax can be found here. You can also use the default notepad shipped with windows to edit and view a batch file, although it does not offer syntax highlighting.
To open notepad:
- Press Win 𐌎+R, type
notepadand then press Enter.
Alternatively, the most "primitive" way to create a batch file is to redirect output from the command line to a file, eg.
echo hello world to the file
You can edit a batch file by right clicking the file and selecting "Edit" from the context menu.
To view the contents of a batch file from within a command prompt, run the following command:
You can also start editing your batch file with notepad from the command prompt by typing
To get help on a batch file command you can use the built-in help.
Open a command prompt (whose executable is
cmd.exe) and enter
help to see all available commands.
To get help for any of these commands, type
help followed by the name of the command.
Some commands will also display help if followed by
Help will only display the help for internal commands.
Opening a Command Prompt
The command prompt comes pre-installed on all Windows NT, Windows CE, OS/2 and eComStation operating systems, and exists as
cmd.exe, typically located in
On Windows 7 the fastest ways to open the command prompt are:
Press Win 𐌎, type "cmd" and then press Enter.
Press Win 𐌎+R, type "cmd" then then press Enter.
If you have an explorer window open, type "cmd" in the address bar to open a prompt in the currently selected directory.
Right-click a folder in Explorer while holding Shift and select "Open command window here".
It can also be opened by navigating to the executable and double-clicking on it.
In some cases you might need to run
cmd with elevated permissions, in this case right click and select "Run as administrator". This can also be achieved by pressing Control+Shift+Enter instead of Enter when using way 1 of the points above.
