title: I am not able to locate the files manually that I am getting from terminal "ls" output
body: <p>I installed docker container from <a href="https://github.com/ShixiangWang/install_GISTIC" rel="nofollow noreferrer">Githunb</a>. It is working smoothly via run_docker.sh command. Everything is working as desired but I am not able to locate the input files present at directories mentioned in &quot;run_docker.sh&quot; script.</p>
  <p>So I run the command as mentioned at Github page</p>
  <pre><code>(base) smtpn@smtpn-Nitro:~$ sudo docker run -it --rm --entrypoint bash shixiangwang/gistic
  </code></pre>
  <p>And then I use &quot;ls&quot; to check the files present in that directory</p>
  <pre><code>(base) root@3340d861afab:/opt/GISTIC# ls
  </code></pre>
  <p>The output list all directory, required to run docker. However, when I go to the directory <code>/opt/</code>   manually through nautilus or nemo file manager, I am not able to locate any directory/folder (hidden folder view is on) which I am getting from terminal output.
  How can I see the same list of folders which I am getting from the terminal output?</p>
  <p>It is very strange and do not know why it is happening.</p>
  <p>Any help will be appreciated.</p>
  <p>Thank you</p>
