[NTLUG:Discuss] sed question

[Ralph Green, Jr]

Burton,
  Your code worked well enough, just as it was.  My original hope was to
have the substitution take place where the first matching server line
was found.  Your version puts them at the bottom of the file, which
works fine and is plenty good for now.  Now, I just need to get the PHP
scripts to call the awk script.  I know the exec  command.  I just have
to get it to run on this system.  Isn't debugging PHP fun?
Thank you for your help,
Ralph
