title: How to read/write wxpython textctrl input in linux platform?
body: <p>I have a GUI created using wxpython where the path to a file fetched from a file dialog resides in textctrl which i named as Repofield.</p>
  
  <pre><code>self.Repofield=wx.TextCtrl(panel, pos=(120,25), size=(250,20))
  value=self.Repofield.SetValue(dlg.GetPath())
  </code></pre>
  
  <p>Now i pass the '<strong>value</strong>' to a command using subprocess:</p>
  
  <pre><code>cmd="./flash -0 -f %s"%(value)  
  proc=subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE, universal_newlines=True)
  out,err=proc.communicate()
  </code></pre>
  
  <p>In windows, we do write the filepath to registry and read from it(runtime) when needed.How does it work in linux?</p>
