title: How to remove first character from first line using sed
body: <p>I have three .csv files that are output from saving a query in MS SQLServer. I need to load these files into an Informix database, which requires that tacking on of a trailing delimiter. That's easy to do using sed</p>
  
  <p><code>s/$/,/g</code></p>
  
  <p>However, each of these files also contains (as displayed by vim, but not ed or sed) an  at the first character position of the first line. </p>
  
  <p>I need to get rid of this character. It deletes as one character using vim's <code>x</code> command. How can I describe this character using sed so I can delete it without removing the line.</p>
  
  <p>I've tried <code>1s/^.//g</code>, but that is not working.</p>
