Ever perform a cat command on a binary file at the command line? Usually, you get a screen full of bizarre characters, and sometimes you end up with a terminal that's unusable. Rather than having to close the terminal and re-open it, just issue a reset command:
And, all should go back to normal. Sometimes the carriage return may stop working in your terminal, in which case, you need to do the following to make reset work:
<LF> is the line-feed character, normally Ctrl-J.
If you ever need to download an entire Web site, perhaps for off-line viewing, wget can do the job—for example:
$ wget \ --recursive \ --no-clobber \ --page-requisites \ --html-extension \ --convert-links \ --restrict-file-names=windows \ --domains website.org \ --no-parent \ www.website.org/tutorials/html/
This command downloads the Web site www.website.org/tutorials/html/.
The options are:
--recursive: download the entire Web site.
--domains website.org: don't follow links outside website.org.
--no-parent: don't follow links outside the directory tutorials/html/.
--page-requisites: get all the elements that compose the page (images, CSS and so on).
--html-extension: save files with the .html extension.
--convert-links: convert links so that they work locally, off-line.
--restrict-file-names=windows: modify filenames so that they will work in Windows as well.
--no-clobber: don't overwrite any existing files (used in case the download is interrupted and resumed).
You can check your computer's temperature using only standard tools, with the command:
$ cat /proc/acpi/thermal_zone/*/temperature
Depending on your hardware, you may have more than one sensor.
This method of checking your computer's temperate works only if ACPI thermal zones are supported on your computer. Most laptops and some desktop systems support them.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
