title: Changing environment variable of a running process
body: <p>I have a script that exports an environment variable and starts some subscripts.</p>
  <pre><code>export LOGLEVEL=&quot;1&quot;
  /home/myuser/bin/myscript1.sh
  /home/myuser/bin/myscript2.sh
  </code></pre>
  <p><code>LOGLEVEL</code> is available to the processes started from the subscripts. How can I change the environment variable <code>LOGLEVEL</code>?</p>
  <p>I have tried to set the variable with <code>export LOGLEVEL=&quot;5&quot;</code> but that`s not working.</p>
