+ +
+ +

As I am continuing to check items off my TODO list before school starts, I have come to an item I have been putting off for a while. Clean up GitHub Account. Luckily, I discovered a little trick to make the process of deleting unused repos a little easier!

+ +

Getting a list of repos to delete

+

I could have automated this, but I prefer a little control. To get the list, start by opening up a new Firefox window with a single tab. In this tab, open your GitHub profile to the list of repos. +Starting from the top, scroll through, and middle click on anything you want to delete. This opens it in a new tab.

+ +

Once you have a bunch of tabs open with repos to remove, use this Firefox plugin to create a plaintext list of every link you opened, and paste the list of links into VS-code.

+ +

Getting an API token

+

Next, an API token is needed. Go to GitHub’s token settings, and generate a new one (make sure to enable repository deletion).

+ + +

With our new token, and out VS-code file, we can start “parsing” the data.

+ +

Pressing CTRL + F brings up the Find/Search toolbar. In the text box, there are a few icons. Pressing the one farthest to the right will enable Regex mode. With this set, paste the following:

+
https://github.com/
+
+ +

Now, click the arrow on the left to enable replace mode, and put this in the new box:

+
curl -XDELETE -H 'Authorization: token <API token from above>' "https://api.github.com/repos/
+
+ +

Then press replace all.

+ +

Finally, replace the contents of the first box with:

+
\n
+
+ +

and the second with:

+
"\n
+
+ +

and replace all again.

+ +

Deleting the repos

+

Simply copy the entire text file that was made, and paste it in a terminal, then press <enter> (this will take a while)

I had a lot of fun with this tool, and a very stripped down version of it actually ended up as a bonus question on the <a href="https://github.com/frc5024/Programming-Test/blob/master/test.md">5024 Programming Test</a> for 2018/2019. Yes, the key was in fact <code class="highlighter-rouge">5024</code>.</p> <p>This tool had some issues. Firstly, the code was a mess and only accepted hard-coded values. This made it very impractical as an every-day tool, and a nightmare to continue developing. Secondly, the encoder made use of entropy bits, and self modifying keys that would end up producing encoded files &gt;1GB from just the word <em>hello</em>.</p> @@ -567,122 +602,4 @@ ibus-daemon <span class="nt">-drx</span> <p>This one is interesting.

I would object to this title, but it is quite accurate. So, here are some of the things I like playing with in python. None of these are actually breaking the language, just little known facts and syntax. At some point I will share about actually breaking the language.

-</code></pre></div></div> - -<p>Can usually get you much farther with your goal of world domination.</p> - -<h2 id="how-does-this-work">How does this work?</h2> -<p>BashSmash abuses bash wildcards, octal escape codes, and a large number of backslashes to obfuscate any valid shell script.</p> - -<p>Firstly, it is important to know that <code class="highlighter-rouge">printf</code> will gladly convert any octal to a string, and bash’s eval (<code class="highlighter-rouge">$()</code>) function will gladly run any string as a bash script. (See where this is going?)</p> - -<p>Because of these tools, we know that the following is possible:</p> -<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"># Printf-ing a string will print the string</span> -<span class="nb">printf</span> <span class="s2">"hello"</span> <span class="c"># This will return hello</span> - -<span class="c"># Printf-ing a sequence of octal escapes will also print a string</span> -<span class="nb">printf</span> <span class="s2">"</span><span class="se">\1</span><span class="s2">50</span><span class="se">\1</span><span class="s2">45</span><span class="se">\1</span><span class="s2">54</span><span class="se">\1</span><span class="s2">54</span><span class="se">\1</span><span class="s2">57"</span> <span class="c"># This will also return hello</span> - -<span class="c"># Eval-ing a printf of an octal escape sequence will build a string, then run it in bash</span> -<span class="si">$(</span><span class="nb">printf</span> <span class="s2">"</span><span class="se">\1</span><span class="s2">50</span><span class="se">\1</span><span class="s2">45</span><span class="se">\1</span><span class="s2">54</span><span class="se">\1</span><span class="s2">54</span><span class="se">\1</span><span class="s2">57"</span><span class="si">)</span> <span class="c"># This will warn that "hello" is not a valid command</span> -</code></pre></div></div> - -<p>This has some issues. You may have noticed that letters are required to spell <code class="highlighter-rouge">printf</code>, and numbers are needed for the octal escapes. Let’s start by fixing the letters problem.</p> - -<p>Bash allows wildcards. You may have run something like <code class="highlighter-rouge">cp ./foo/* ./bar</code> before. This uses the wildcard <code class="highlighter-rouge">*</code>. The <code class="highlighter-rouge">*</code> wildcard will be auto-evaluated to expand into a list of all files in it’s place.</p> -<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"># Let's assume that ./foo contains the following files:</span> -<span class="c"># john.txt</span> -<span class="c"># carl.txt</span> - -<span class="c"># Running the following:</span> -<span class="nb">cat</span> ./foo/<span class="k">*</span> - -<span class="c"># Will automatically expand to:</span> -<span class="nb">cat</span> ./foo/john.txt ./foo/carl.txt - -<span class="c"># Now, lets assume that ./baz contains a single file:</span> -<span class="c"># KillHumans.sh</span> - -<span class="c"># Running:</span> -./baz/<span class="k">*</span> - -<span class="c"># Will execute KillHumans.sh</span> -</code></pre></div></div> - -<p>Neat, Right? To take this a step further, you can use the second wildcard, <code class="highlighter-rouge">?</code>, to specify the number of characters you want to look for. Running <code class="highlighter-rouge">./baz/?</code> will not run <code class="highlighter-rouge">KillHumans.sh</code> because <code class="highlighter-rouge">KillHumans.sh</code> is not 1 char long. But <code class="highlighter-rouge">./baz/?????????????</code> will. This is messy, but it works.</p> - -<p>Now, back to our problem with <code class="highlighter-rouge">printf</code>. <code class="highlighter-rouge">printf</code> is located in <code class="highlighter-rouge">/usr/bin/printf</code> on all *nix systems. This is handy as, firstly, this can be wildcarded, and secondly, the path contains 2 <code class="highlighter-rouge">n</code>’s and an <code class="highlighter-rouge">f</code> (the two letters we are allowed to use). So, instead of calling <code class="highlighter-rouge">printf</code>, we can call <code class="highlighter-rouge">/???/??n/???n?f</code>.</p> -<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"># Now, we can call:</span> -/???/??n/???n?f <span class="s2">"</span><span class="se">\1</span><span class="s2">50</span><span class="se">\1</span><span class="s2">45</span><span class="se">\1</span><span class="s2">54</span><span class="se">\1</span><span class="s2">54</span><span class="se">\1</span><span class="s2">57"</span> - -<span class="c"># To print "hello". Or:</span> -<span class="si">$(</span>/???/??n/???n?f <span class="s2">"</span><span class="se">\1</span><span class="s2">50</span><span class="se">\1</span><span class="s2">45</span><span class="se">\1</span><span class="s2">54</span><span class="se">\1</span><span class="s2">54</span><span class="se">\1</span><span class="s2">57"</span><span class="si">)</span> - -<span class="c"># To run "hello" as a program (still gives an error)</span> -</code></pre></div></div> - -<p>Now, our problem with letters is solved, but we are still using numbers.</p> - -<p>Bash allows anyone to define functions. These functions can take arguments and call other programs. So, what if we have a function that can take any number of arguments, and return the number of arguments as a number? This will be helpful because an empty argument can be added with <code class="highlighter-rouge">""</code> (not a number or letter), and this will replace the need for numbers in our code. On a side note, bash allows <code class="highlighter-rouge">__</code> as a function name, so that’s cool.</p> - -<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"># Our function needs to do the following:</span> -<span class="c"># - Take any number of arguments</span> -<span class="c"># - Turn the number to a string</span> -<span class="c"># - Print the string so it can be evaluated back to a number with $()</span> - -<span class="c"># First, we start with an empty function, named __ (two underscores)</span> -__<span class="o">()</span> <span class="o">{}</span><span class="p">;</span> - -<span class="c"># Easy.

First, we must tell bash that our <code class="highlighter-rouge">__</code> function exists.</p> -<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"># We do this by starting our new script with: </span> -__<span class="o">()</span> <span class="o">{</span>/???/??n/???n?f <span class="k">${#}</span><span class="o">}</span><span class="p">;</span> - -<span class="c"># Next, an eval to actually run our constructed string.
