Scroll down either with the mouse scroll wheel, by pressing the Page Down key or pushing the down arrow key on your keyboard. Many man pages that otherwise wouldn’t be referenced by command names can be accessed in the same way.
#Command that shows active tables linux manual#
More than likely you’ve become quite accustomed to looking up the manual pages for commands using the CLI man command, but you may not be as used to the built-in Linux Programmer’s Manual. You’ll be greeted with the technical definition of what ASCII is, followed by a table of the 128 characters that make up the proper ASCII standard. At the Bash prompt, type the command man ASCII and then push enter.
If you’re already within a Linux CLI environment operating from the Bash shell, then you can use the built-in Linux Programmer’s Manual without skipping a beat. After you know the tricks to access this information, you’ll find that it’s much faster than looking it up on the Internet or reaching for an actual coder’s manual. This technology is still quite useful, especially in a world that demands more and more development for mobile platforms. Linux has a number of built-in programmer tools to solve these sorts of problems, but they’re largely obscured from modern users. These numeric values are more or less platform-independent, so if you author your own code on Linux for use on another platform knowing these values from inside Linux is still worthwhile. Programming an app or authoring a Web page could be easier if you know the specific numeric values that are mapped to different characters. While we view characters like letters, numbers, and symbols, the underlying system code sees them only as a series of numeric values.
If your author smartphone apps or you’re a Web developer, then the time might come that you need some advanced information on how apps interact with individual characters.
