Requires aria2c but could just as easily wget or anything else.
A great way to build up a nice font collection for Gimp without having to waste a lot of time. :-)
pvl 'link1' 'link2' 'link3'
Play Youtube, Vimeo, etc links without visual elements.
Great for music videos when you just want the audio.
You can control mplayer with this!
Hit Ctrl-C twice to exit (if you're playing multiple files)
#4345 also works under windows
This command lets you see and scroll through all of the strings that are stored in the RAM at any given time. Press space bar to scroll through to see more pages (or use the arrow keys etc).
Sometimes if you don't save that file that you were working on or want to get back something you closed it can be found floating around in here!
The awk command only shows lines that are longer than 20 characters (to avoid seeing lots of junk that probably isn't "human readable").
If you want to dump the whole thing to a file replace the final '| less' with '> memorydump'. This is great for searching through many times (and with the added bonus that it doesn't overwrite any memory...).
Here's a neat example to show up conversations that were had in pidgin (will probably work after it has been closed)...
$sudo cat /proc/kcore | strings | grep '([0-9]\{2\}:[0-9]\{2\}:[0-9]\{2\})'
(depending on sudo settings it might be best to run
$sudo su
first to get to a # prompt)
wmr - | pv -s $SIZEOFMEM | ssh -p 40004 -c arcfour,blowfish-cbc -C root@savelocation.com "cat - > /forensics/T430-8gb-RAM1.dd"
Run above command from Windows Cygwin:
On Windows: Install Cygwin, and copy WMR (windows memory reader 1.0) memory diagnostic into cygwin\bin folder, also install cygwins netcat and ssh (openssh). I recommend installing apt-cyg and running "
On Linux: Have an SSH Server
SIMPLEST FORM:
WINDOWS: # wmr - | ssh root@savelocation.com "cat - > /tmp/FileToSave.dd"
For more details on how to extract information from memory dump:
apt-get install foremost
foremost -t all -T -i /forensics/T430-8gb-RAM1.dd

An old USB A/B cable is all you need to make your own Smart Home hardware!
Cut off and discard the B-portion of the USB cable. On the A side, connect the RED (+) and WHITE (D-) wires via a 1 kiloohm resistor.

Now plug the cable into a USB port on your Linux computer. Your hardware is ready!
Run the above command after changing variable mysms to your personal email-to-SMS gateway info as required by your cellular service provider.
The command uses the amazing usbmon tool (see link below) to detect the cable.
For the curious, to view the raw usbmon output, run this command: (Also see the sample output)
$usbmon -i usb0
How does it work? When the red and white wires are connected (via the 1 kiloohm resistor) the USB hardwere is tricked into thinking that a new USB device is trying to start up.
We then use the usbmon utility to capture the host USB events as it tries to talk to the cable.
The expect utility watches the usbmon stream and waits for the disconnect text "-2:128" before sending the SMS message.
Finally, the sendmail tool is used to email the SMS message to your smartphone via your cellular provider's SMS-to-email gateway.
As a result, when the electrical connection between the red and white wire is interrupted, or the USB cable is unplugged from your computer, you get an SMS notification of the disconnect event on your smartphone.
Could this be the cheapest smart home gadget ever? What are YOU going to sense with it?
