Running Dtrce after i run my process shows it as an invalid Command
<p>I have written a small program and a dtrace script .  I have compiled a program as <code>g++ CCtest</code> . The dtrace script name is <code>./CCstack.d</code> . After compilation , I am running the <code>./a.out</code> . and have induced sleep in main function before it starts executing things . Then 
on a second console i have given the command <code>dtrace -s ./CCstack.d | c++filt</code>. This is giving a dtrace usage DISPLAY <code>Usage /usr/bin/dtrace [--help] [-h | -G] [-C [-I&lt;Path&gt;]] -s File.d [-o &lt;File&gt;]</code> . I am unable to figure out whats wrong here with my command . I have also tried <code>dtrace -p &lt;pid of ./a.out &gt; -s ./CCstack.d | c++filt</code> . Using a <code>gc++filt</code> instead of <code>c++filt</code> gives a console message did you mean <code>c++filt</code>. I am using Ubuntu</p>
