Yeah, I've only ever used it while at work. I just copied it to my home computer for this thread.

This one takes youtube channel URLs from the clipboard (using xclip) or $1 if present, and gives you the RSS feed for that channel in the clipboard: #!/bin/bash
if [[ $1 == '' ]]
then start=$(xclip -selection clipboard -o) channel=$(curl -s $start | head -n 2500 | egrep -o data-channel-external-id=\"........................\" | head -1) channelid=$(echo $channel | sed s/data-channel-external-id=\"// | sed s/\"//) prefix=$(echo "youtube.com/feeds/videos.xml?channel_id=") echo $prefix$channelid | xclip -selection clipboard -i
else channel=$(curl -s $1 | head -n 2500 | egrep -o data-channel-external-id=\"........................\" | head -1) channelid=$(echo $channel | sed s/data-channel-external-id=\"// | sed s/\"//) prefix=$(echo "youtube.com/feeds/videos.xml?channel_id=") #echo $prefix$channelid echo $prefix$channelid | xclip -selection clipboard -i

for converting 565 VGA framebuffers to usable PNGs, e.g. after doing /dev/fb0 > screen.raw
use this (which I found, not mine): #!/usr/bin/perl -w $w = shift || 450; $h = shift || 800; $pixels = $w * $h;
open OUT, "|pnmtopng" or die "Can't pipe pnmtopng: $!\n";
printf OUT "P6%d %d\n255\n", $w, $h;
while ((read STDIN, $raw, 2) and $pixels--) { $short = unpack('S', $raw); print OUT pack("C3", ($short & 0xf800) >> 8, ($short & 0x7e0) >> 3, ($short & 0x1f)

what does this do wit your disks
Joshua Walker
Fills MBR and other shit with zeros
Easton Nguyen
Why? ;_;
Also why not use /dev/null instead of /dev/zeron?
Dylan Martinez
Not sure if bait or not, but do it and you're fucked for good. dd = disk destroyer.
Sebastian Fisher
>Why? ;_; Because I need to fill the beginning of drive with zeros, to make sure that custom boot loader will work as intended. >Also why not use /dev/null instead of /dev/zeron? null is one symbol, with 1 byte size (I think), and zero - infinitive number of zeros. dd is command to write files directly to drive.
Adrian Rivera
Ok, so you're genuinely asking this. It makes no sense to dd zeros onto /dev/sd1, because most of the time your os is installed to that particular partition, bombarding it with zeros or random data will fuck up your system for good. I did migrate OSs a lot of times using dd and co, but I'd advise against it if you do not absolutely positively know what you're doing.
Can you elaborate more why you're running this command?

right but how do u run/view it. No experience with it.

try going to the site with your browser, firefox at least has a built in rss feed reader

You could merge the channel and channelid lines if you use a positive lookbehind.

Dang, that pushbullet one is nice.
Anymore like that that can be used in a lot situations?

Jow Forums has a json api, you know. Not only is it easier to parse, but it gives you actual file sizes in bytes as opposed to rounded KB/MB values. This thread: a.4cdn.org/g/thread/65461068.json (grep for "fsize")

>Dang, that pushbullet one is nice. Can you explain how that's useful please? I have no idea how pushbullet works... thanks.
Pushbullet has a bunch of different features, most of them involving push notifications.
For instance, if you have the chrome extension installed, there a submenu of your devices in the right click menu that you can send the link to your device. Or from your device you can use the share feature of apps to send content or links from one devices to other devices or to your desktop browser.
The script just uses pushbullet's API to send a push notification to your device but it's pretty useful since you can tack it onto a command that takes a long time to finish so that if you're away from your computer and it finishes you will get a notification on your phone that the task was completed.
Robert Collins
oh, neat! I have a Raspi that I'd like to send notices from. will give it a try.
Jonathan Fisher
Okay, I signed into Pushbullet and I have the access-token but I have no idea what "device_iden" is. How do I get that? Anyone know? Thanks!
Brandon Martin
If you have a device registered with the account (eg. chrome extension installed in desktop browser or mobile app installed on phone/tablet with that account) you can get the device identity by making a request on the device API resource. This command should work, I think curl --header 'Access-Token: :auth_token:' api.pushbullet.com/v2/devices
Caleb Reed
ah, thanks! I actually omitted the device part and it also just werkz.

Samuel Perry
Oh, yeah. If you do that it sends to all devices, I think.
># Make directory and cd into it (for .bashrc) mkcd() { mkdir -p $1; cd $1; } fuck that's shitty programming.
Aaron Allen
It works mate. If you wanna improve it, please do.

he didn't write that. and it's not mean. it's just blunt. are you new to Jow Forums? seems so.

that will work a little better, thanks

It optimised boot speed by writing zeros to unused areas of your disk
Justin Cruz
np
Elijah Green
to actually do that (zero-fill); cd /folder/on/desired/mount; pv < /dev/zero > fill.bin; rm fill.bin doesn't do anything for boot speed, but can be useful to wipe out recoverable deleted files
Brandon Nelson
is this any different than shred -ufz?

shred is for overwriting a file, not zeroing slack space
