Creating multi-page PDF files with GIMP and `convert` « Patrick's WebLog. Occasionally I have to sign some document (old style, with a pen) and send it electronically. Sometimes those are multi-page documents. Since it is uncommon to send it back as multiple image files after scanning, and multi-page image formats are uncommon as well, I’d like to send them as PDF file. Before I discovered this method, I used to insert the scanned images into OpenOffice Writer, and then create the PDF with it.
This works, but it is a bit cumbersome to tell OpenOffice Writer to maximise the images (eliminating page borders, etc.), especially when there are a lot of pages. It just doesn’t feel like a real solution. So, here we go: Prerequisites: GIMP (I’m currently at version 2.6.8, but this will probably work with older versions as well)GraphicsMagick (tested with 1.3.8) or ImageMagick (tested with 6.5.8.8) Procedure: Get the scanned pages opened as layers of one image in GIMP. That’s it – you now have your PDF file ready for sending!
UsingTheTerminal. "Under Linux there are GUIs (graphical user interfaces), where you can point and click and drag, and hopefully get work done without first reading lots of documentation. The traditional Unix environment is a CLI (command line interface), where you type commands to tell the computer what to do. That is faster and more powerful, but requires finding out what the commands are. " -- from man intro(1) This page gives an introduction to using the command-line interface terminal, from now on abbreviated to the terminal. There are many varieties of Linux, but almost all of them use similar commands that can be entered from the terminal. There are also many graphical user interfaces (GUIs), but each of them works differently and there is little standardization between them.
Experienced users who work with many different Linux distributions therefore find it easier to learn commands that can be used in all varieties of Ubuntu and, indeed, in other Linux distributions as well.

In this lesson, I will introduce your first three commands: pwd (print working directory), cd (change directory), and ls (list files and directories). If you have not worked with a command line interface before, you will need to pay close attention to this lesson, since the concepts will take some getting used to. File System Organization Like that legacy operating system, the files on a Linux system are arranged in what is called a hierarchical directory structure. This means that they are organized in a tree-like pattern of directories (called folders in other systems), which may contain files and other directories.
The first directory in the file system is called the root directory. The root directory contains files and subdirectories, which contain more files and subdirectories and so on and so on. Most graphical environments today include a file manager program to view and manipulate the contents of the file system. Pwd [me@linuxbox me]$ pwd /home/me [me@linuxbox me]$ ls cd.
