'^@' is ascii octal '000'
tr -d '\000' myFile

Vgresh,

It's giving me following error.

tr -d '\000' a(my file name)


tr: The combination of options and String parameters is not legal.
Usage: tr [ -c | -cds | -cs | -ds | -s ] [-A] String1 String2
tr [ -cd | -cs | -d | -s ] [-A] String1

  1. why do you need 'cat'?
  2. '^@' is ONE character. How exactly does using the '\' help you

Sorry, I missed the details in original post - if it's one character, you have to use the octal.
