Introduction[ edit ] This book addresses bit Windows commands applicable to modern versions of Windows based on the Windows NT environment. You can find out which version of cmd. This book first describes using the Windows NT command interpreter, how it receives, parses, and processes commands from users. Then it describes various commands available. To obtain an extensive list of Windows commands and their short summaries, open the command prompt on any Windows computer, and type help. The subject of this book is also known as "batch programming", even though "batch" refers not only to batch files for MS DOS and Windows command interpreter. Other subject terms include "batch file programming", "batch file scripting", "Windows batch command", "Windows batch file", "Windows command line", "Windows command prompt", and "Windows shell scripting". Using the Windows command interpreter[ edit ] How a command line is interpreted[ edit ] The parsing of a command line into a sequence of commands is complex, and varies subtly from command interpreter to command interpreter. There are, however, four main components: Variable substitution A command line is scanned for variable specifications, and any found are replaced with the contents of those variables.

As noted above, when using MS Windows console command. This is intended to be a quick way to invoke ghostscript to convert one or more input files. For instance, to convert somefile. Individual documents can and often do specify a paper size, which takes precedence over the default size.

The default set of paper sizes will be included in the currentpagedevice in the InputAttributes dictionary with each paper size as one of the entries. The last entry in the dictionary which has numeric keys is a non-standard Ghostscript extension type of PageSize where the array has four elements rather than the standard two elements. This four element array represents a page size range where the first two elements are the lower bound of the range and the second two are the upper bound. By default these are [0, 0] for the lower bound and [16 fffff, 16 fffff] for the upper bound.

For actual printers, either the entire InputAttributes dictionary should be replaced or the range type entry should not be included.

Using this option will result in automatic rotation of the document page if the requested page size matches one of the default page sizes. This allows the -dPSFitPage option to fit the page size requested in a PostScript file to be rotated, scaled and centered for the best fit on the specified page. See the section on finding files for details. Sometimes the initialization files are compiled into Ghostscript and cannot be changed. On Windows and some Linux builds, the default paper size will be selected to be a4 or letter depending on the locale.

Interacting with pipes As noted above, input files are normally specified on the command line. However, one can also "pipe" input into Ghostscript from another program by using the special file name '-' which is interpreted as standard input.

Because of this, options and files after the '-' in the command line will be ignored. On Unix and MS Windows systems you can send output to a pipe in the same way. In the last case, -q isn't necessary since Ghostscript handles the pipe itself and messages sent to stdout will be printed as normal. All the normal switches and procedures for interpreting PostScript files also apply to PDF files, with a few exceptions. This is useful for creating fixed size images of PDF files that may have a variety of page sizes, for example thumbnail images.

This option is also set by the -dFitPage option. If neither of these is specified, the output will use the screen options for any output device that doesn't have an OutputFile parameter, and the printer options for devices that do have this parameter. This may include any extra bleed area needed to accommodate the physical limitations of cutting, folding, and trimming equipment.

The actual printed page may include printing marks that fall outside the bleed box. The trim box defines the intended dimensions of the finished page after trimming.

Some files have a TrimBox that is smaller than the MediaBox and may include white space, registration or cutting marks outside the CropBox.

Using this option simulates appearance of the finished printed page. The art box defines the extent of the page's meaningful content including potential white space as intended by the page's creator. The art box is likely to be the smallest box. It can be useful when one wants to crop the page as much as possible without losing the content. Unlike the other "page boundary" boxes, CropBox does not have a defined meaning, it simply provides a rectangle to which the page contents will be clipped cropped.

By convention, it is often, but not exclusively, used to aid the positioning of content on the usually larger, in these cases media. For files created with encryption method 4 or earlier, the password is an arbitrary string of bytes; with encryption method 5 or later, it should be text in either UTF-8 or your locale's character set Ghostscript tries both.

Annotations are shown by default. Annoation types listed in this array will be drawn, whilst those not listed will not be drawn. By default, AcroForm is not enumerated because Adobe Acrobat doesn't do this. This option may be useful for debugging or recovery of incorrect PDF files that don't associate all annotations with the page objects.

This may be useful for backward compatibility with old versions of Ghostscript and Adobe Acrobat, or for processing files with large values of UserUnit that otherwise exceed implementation limits.

On TrueType fonts, this is often a hollow sqaure. Ghostscript now attempts to mimic this undocumented feature using a user parameter RenderTTNotdef. Pages of all documents in PDF collections are numbered sequentionally. A list can include single pages or ranges of pages. Ranges of pages use the minus sign '-', individual pages and ranges of pages are separated by commas ','.

A trailing minus '-' means process all remaining pages. You can specify new-path in two ways: absolute or relative. Enclosed with double quotes if pathname contains blank. You can cd in multiple stages e. For example, to compile a Java program called "Hello.

You can use wildcards for pattern matching. Windows Graphical Interface - File Explorer You could, of course, view the contents of a directory folder using the Windows' "File Explorer" more conveniently.

But, Windows' File Explorer, by default, will not show the file extension. Windows' File Explorer, by default, will not display hidden files and directories e.

To display the hidden items, choose "View" menu, check "Hidden Items". Tips and Tricks You can click on the "folder name" to get the full pathname of the current folder. Press TAB key repeatably to cycle through all the matches. Once enabled, you can right-click to copy the highlighted text, and another right-click to paste on the command-line.

ESC Key: Clear command-line. You should set to a bigger number , so that you can view more old messages. Keyboard Shortcuts for Windows Good programmers uses keyboard shortcuts instead of mouse to perform most of the editing tasks, such as positioning the cursor, selecting texts, copy and paste.

Below are the frequently-used keyboard shortcuts for the programmers. Keyboard Shortcut.
