<h1>Netscript Basic Functions<a class="headerlink" href="#netscript-basic-functions" title="Permalink to this headline"></a></h1>
<p>This page contains the complete documentation for all functions that are available in Netscript.
This includes information such as function signatures, what they do, and their return values.</p>
<p>At the end is also a section that describes how to define your own functions in Netscript.</p>

<p>Function that is used to try and hack servers to steal money and gain hacking experience. The runtime for this command depends
on your hacking level and the target server's security level. In order to hack a server you must first gain root access
to that server and also have the required hacking level.</p>
<p>A script can hack a server from anywhere. It does not need to be running on the same server to hack that server. For example,
you can create a script that hacks the 'foodnstuff' server and run that script on any server in the game.</p>
<p>A successful hack() on a server will raise that server's security level by 0.002.</p>
<p>Example:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">hack</span><span class="p">(</span><span class="s2">&quot;foodnstuff&quot;</span><span class="p">);</span>
<span class="n">hack</span><span class="p">(</span><span class="s2">&quot;10.1.2.3&quot;</span><span class="p">);</span>

<div class="section" id="grow">
<h2>grow<a class="headerlink" href="#grow" title="Permalink to this headline"></a></h2>
<dl class="function">

<code class="descname">grow</code><span class="sig-paren">(</span><em>hostname/ip</em><span class="sig-paren">)</span></dt>

<tr class="field-even field"><th class="field-name">Returns:</th><td class="field-body"><p class="first last">The number by which the money on the server was multiplied for the growth</p>
</td>
</tr>
</tbody>
</table>
<p>Use your hacking skills to increase the amount of money available on a server. The runtime for this command depends on your hacking
level and the target server's security level. When grow() completes, the money available on a target server will be increased by a
certain, fixed percentage. This percentage is determined by the target server's growth rate (which varies between servers) and security level.
Generally, higher-level servers have higher growth rates. The getServerGrowth() function can be used to obtain a server's growth rate.</p>
<p>Like hack(), grow() can be called on any server, regardless of where the script is running. The grow() command requires
root access to the target server, but there is no required hacking level to run the command. It also raises the security level
of the target server by 0.004.</p>
<p>Example:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">grow</span><span class="p">(</span><span class="s2">&quot;foodnstuff&quot;</span><span class="p">);</span>

<p>Use your hacking skills to attack a server's security, lowering the server's security level. The runtime for this command
depends on your hacking level and the target server's security level. This function lowers the security level of the target
server by 0.05.</p>

<p>Kills the script on the target server specified by the script's name and arguments. Remember that scripts
are uniquely identified by both their name and arguments. For example, if <em>foo.script</em> is run with the argument 1, then this
is not the same as <em>foo.script</em> run with the argument 2, even though they have the same code.</p>
<p>If this function successfully kills the specified script, then it will return true. Otherwise, it will return false.</p>

for scripts is case-sensitive, but for other types of files it is not. For example, <em>fileExists(&quot;brutessh.exe&quot;)</em>

<p>Purchased a server with the specified hostname and amount of RAM.</p>
<p>The <em>hostname</em> argument can be any data type, but it will be converted to a string and have whitespace removed. Anything that resolves to an empty string will
cause the function to fail. If there is already a server with the specified hostname, then the function will automatically append
a number at the end of the <em>hostname</em> argument value until it finds a unique hostname. For example, if the script calls
<em>purchaseServer(&quot;foo&quot;, 4)</em> but a server named &quot;foo&quot; already exists, the it will automatically change the hostname to &quot;foo-0&quot;. If there is already
a server with the hostname &quot;foo-0&quot;, then it will change the hostname to &quot;foo-1&quot;, and so on.</p>
<p>Note that there is a maximum limit to the amount of servers you can purchase.</p>
<p>Returns the hostname of the newly purchased server as a string. If the function fails to purchase a server, then it will return an
empty string. The function will fail if the arguments passed in are invalid, if the player does not have enough money to purchase
the specified server, or if the player has exceeded the maximum amount of servers.</p>

<h3>Defining your own Functions<a class="headerlink" href="#defining-your-own-functions" title="Permalink to this headline"></a></h3>
<p>You can define your own functions in Netscript using the following syntax:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">function</span> <span class="n">name</span><span class="p">(</span><span class="n">args</span><span class="o">...</span><span class="p">)</span> <span class="p">{</span>
<span class="n">function</span> <span class="n">code</span> <span class="n">here</span><span class="o">...</span>
<span class="k">return</span> <span class="n">some_value</span>
<span class="p">}</span>
</pre></div>
</div>
<p>Functions should have some return value. Here is an example of defining and using a function:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">function</span> <span class="nb">sum</span><span class="p">(</span><span class="n">values</span><span class="p">)</span> <span class="p">{</span>
<span class="n">res</span> <span class="o">=</span> <span class="mi">0</span><span class="p">;</span>
<span class="k">for</span> <span class="p">(</span><span class="n">i</span> <span class="o">=</span> <span class="mi">0</span><span class="p">;</span> <span class="n">i</span> <span class="o">&lt;</span> <span class="n">values</span><span class="o">.</span><span class="n">length</span><span class="p">;</span> <span class="o">++</span><span class="n">i</span><span class="p">)</span> <span class="p">{</span>
<span class="n">res</span> <span class="o">+=</span> <span class="n">values</span><span class="p">[</span><span class="n">i</span><span class="p">];</span>
<span class="p">}</span>
<span class="k">return</span> <span class="n">res</span><span class="p">;</span>
<span class="p">}</span>
<span class="nb">print</span><span class="p">(</span><span class="nb">sum</span><span class="p">([</span><span class="mi">1</span><span class="p">,</span> <span class="mi">2</span><span class="p">,</span> <span class="mi">3</span><span class="p">,</span> <span class="mi">4</span><span class="p">,</span> <span class="mi">5</span><span class="p">]));</span>
<span class="nb">print</span><span class="p">(</span><span class="nb">sum</span><span class="p">([</span><span class="mi">1</span><span class="p">,</span> <span class="mi">10</span><span class="p">]));</span>
</pre></div>
</div>
<p>The example above prints the following in its log:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="mi">15</span>
<span class="mi">11</span>
</pre></div>
</div>
<p><strong>Note about variable scope in functions:</strong></p>
<p>Functions can access &quot;global&quot; variables declared outside of the function's scope. However, they cannot change the value of any &quot;global&quot; variables.
Any changes to &quot;global&quot; variables will only be applied locally to the function. This also means that any variable that is first defined inside a
function will NOT be accessible outside of the function.</p>
<p>For example, the following code:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">function</span> <span class="nb">sum</span><span class="p">(</span><span class="n">values</span><span class="p">)</span> <span class="p">{</span>
<span class="n">res</span> <span class="o">=</span> <span class="mi">0</span><span class="p">;</span>
<span class="k">for</span> <span class="p">(</span><span class="n">i</span> <span class="o">=</span> <span class="mi">0</span><span class="p">;</span> <span class="n">i</span> <span class="o">&lt;</span> <span class="n">values</span><span class="o">.</span><span class="n">length</span><span class="p">;</span> <span class="o">++</span><span class="n">i</span><span class="p">)</span> <span class="p">{</span>
<span class="n">res</span> <span class="o">+=</span> <span class="n">values</span><span class="p">[</span><span class="n">i</span><span class="p">];</span>
<span class="p">}</span>
<span class="k">return</span> <span class="n">res</span><span class="p">;</span>
<span class="p">}</span>
<span class="nb">print</span><span class="p">(</span><span class="n">res</span><span class="p">);</span>
</pre></div>
</div>
<p>results in the following runtime error:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">Script</span> <span class="n">runtime</span> <span class="n">error</span><span class="p">:</span>
<span class="n">Server</span> <span class="n">Ip</span><span class="p">:</span> <span class="mf">75.7</span><span class="o">.</span><span class="mf">4.1</span>
<span class="n">Script</span> <span class="n">name</span><span class="p">:</span> <span class="n">test</span><span class="o">.</span><span class="n">script</span>
<span class="n">Args</span><span class="p">:[]</span>
<span class="n">variable</span> <span class="n">res</span> <span class="ow">not</span> <span class="n">defined</span>
</pre></div>
</div>
<p>The following example shows that any change to &quot;global&quot; variable inside a function only applies in the function's local scope:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">function</span> <span class="n">foo</span><span class="p">()</span> <span class="p">{</span>
<span class="n">i</span> <span class="o">=</span> <span class="mi">5</span><span class="p">;</span>
<span class="k">return</span> <span class="s2">&quot;foo&quot;</span><span class="p">;</span>
<span class="p">}</span>
<span class="n">i</span> <span class="o">=</span> <span class="mi">0</span><span class="p">;</span>
<span class="nb">print</span><span class="p">(</span><span class="n">i</span><span class="p">);</span>
<span class="n">foo</span><span class="p">();</span>
<span class="nb">print</span><span class="p">(</span><span class="n">i</span><span class="p">);</span>
</pre></div>
</div>
<p>Results in the following log:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="mi">0</span>
<span class="mi">0</span>
</pre></div>
</div>
<p><strong>Other Notes about creating your own functions:</strong></p>
<p>Defining a function does not create a Javascript function object in the underlying game code. This means that you cannot use any function
you create in functions such as <a class="reference external" href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort">Array.sort()</a> (not yet at least, I'll try to make it work in the future).</p>
