Type dir at the prompt afterward to make sure the file was created fine. Using our fdisk example before, you could try: Issue the following command to receive said file: It’s also possible to convert a man page to a PDF file. Type dir at the prompt to make sure the file is there. For example, if you had wanted to do this with the fdisk command: Replace the “COMMAND” string with the name of the command you want to typeset as a PostScript file. The exact location may differ depending on your particular distribution. Make sure that you are in the Documents folder of your home directory by issuing the command: If your prompt does not end with the “$” symbol, then type bash and press enter. Select a graphical command prompt from the Root Window Menu. Method 1: Converting a Man Page to a PS File Should you need a PDF file, then apply Method 2 after using Method 1. Once you have a PostScript file you can then convert this to the even more portable PDF format.įirst we’ll illustrate how to convert a man page to a PostScript file. The conversion task can be accomplished quite easily at a standard Linux Bash command prompt. You will also need to convert it if you need to read a page in another program, on any other device or if you need to print it out. If you need to share content from a man page, then you will need to convert the file to another format before sharing it with someone who doesn’t have access to the man Linux command. These pages store information about nearly every command stored on a system, and essentially constitute a free source of information installed on every Linux installation, but they’re not portable in the least. These files are stored in such a way that only the man or xman command issued at a command prompt in a Linux environment can read them. Most popular among them are ps2pdf and pdf2ps.Man pages in all versions of Linux are stored as specially formatted and compressed text files, so it’s difficult to share them or read them on other devices. Ghostscript can do many more things other than just converting PDF and Postscript files to images such as viewing files, printing, changing the resolution of the images, rasterize a document, rendering a file in grayscale etc., There are also a number of utility scripts the invokes Ghostscript with appropriate options for converting PDF to Postscript and vice versa. Gs -dNOPAUSE -dBATCH -sDEVICE=png16m –dFirstPage=3 –dLastPage=4 -sOutputFile="Pic-%d.png" input.pdf For example, to convert that pages 3 and 4 of a pdf document named input.pdf, the command is: You could use the options –dFirstPage and –dLastPage to convert specific pages of a multi-page PDF document. Convert specific page(s) of multi-page PDF to PNG dBATCH option causes Ghostscript to exit when processing of the file specified in the command has finished. dNOPAUSE option disables the prompt and pause after each page is processed. The %din the output file name is replaced by the page number hence the PNG files are named pic-1, pic-2, pic3, and so on., for pages 1, 2, 3, respectively. The above command will generate a separate PNG file for each page in the pdf file input.pdf. The last converts EPS to PDF with high resolution bounding box. The first invokes GhostScript to append high resolution bounding box. On top of that, we can automate the whole process We can install it with the. epstool -copy -bbox input.eps output.eps epstopdf -hires output.eps. As a CLI tool, it’s much faster than Gscan2pdf. ImageMagick is a CLI tool which allows you to convert images to PDF. Gs -dNOPAUSE -dBATCH -sDEVICE=png16m -sOutputFile="Pic-%d.png" input.pdf Once we are done with editing, we can convert images into a single PDF: File Save Select Document type to PDF Save. Ghostscript is capable of interpreting PostScript, encapsulated PostScript (EPS), DOS EPS (EPSF), and Adobe Portable Document Format (PDF). To convert a multi-page pdf file and generate separate png file for each page the command is: It can be any available device such as jpeg, tiff32nc, pngmono, etc., For a list of all available devices check help using the command gs -h Convert multi page PDF to PNG files SDevice option specifies the output device. This command will convert a single page pdf file named input.pdf and saves the output to pic-1.png Gs -sDevice=png16m -sOutputFile="pic-1.png" input.pdf In its very simple form Ghostscript can be executed as below: Ghostscript is an interpreter for PDF and PostScript and is available on Windows, Unix, Linux and OpenVMS platforms. However if you want to batch process / automate the conversion of several PDF files then the most efficient tool for this purpose is the Ghostscript. There are several ways you can convert a PDF to an image format such as PNG or JPEG.
