    text
    copied!<p>I want to make some C++ program and I'm using function <code>popen</code> here to send commands to command line in Unix. It works fine, but when I call <code>cd directory</code>, the directory doesn't change. I thing that it's same when I try to run <code>cd directory</code> in some script, after finishing script directory path change back. So, scripts I must run like <code>. ./script.sh</code> not <code>./sript.sh</code>, but how to do that with <code>popen</code> function? I have tried to add <code>". "</code> before first argument of <code>popen</code>, but running <code>". ls"</code> makes error.</p> <p><strong>Code:</strong></p> <pre><code>cout &lt;&lt; "@ Command from " &lt;&lt; session-&gt;target().full() &lt;&lt; ": " &lt;&lt; message.body() &lt;&lt; endl; //cout &lt;&lt; "Prisla zprava" &lt;&lt; endl; //m_session-&gt;send( "Hello World", "No Subject" ); //system( message.body().c_str() ); //if ( message.body() == "" ) FILE* outp; char buffer[100]; string outps = ""; outp = popen( message.body().c_str(), "r" ); while ( !feof(outp) ) { fgets( buffer, 100, outp ); outps = outps + buffer; } pclose(outp); cout &lt;&lt; "&amp; Output from command: " &lt;&lt; outps &lt;&lt; endl; m_session-&gt;send( outps.c_str(), "Output" ); </code></pre> <p>In <code>message.body();</code> is <code>string</code> which I want to run (I'm receiving this from <code>XMPP</code>). When the <code>string</code> is for example <code>"ls"</code>, it returns <code>string</code> with list of files in actual directory. But when the message is <code>"cd directory"</code>, nothing happens, like trying to change directory in scripts.</p>
