title: sed remove a special control character from many files
body: <p>Can someone please give me the exact syntax for removing ^@ from thousands of html files in nested directories using sed? The ^@ is a control character inserted by a windows program that generated these files. I cannot seem to get the syntax right.</p>
  <p>I tried this (but it did not work) using a file since I could not enter the control-character at the command prompt:
  find ./ *.html -type f -exec sed -i 's/^@//g' {} ;</p>
