Maybe nohup is what you looking for?

>From the info pages...

"`nohup' runs the given COMMAND with hangup signals ignored, so that the
command can continue running in the background after you log out.
Synopsis:

     nohup COMMAND [ARG]...

   If standard output is a terminal, it is redirected so that it is
appended to the file `nohup.out'; if that cannot be written to, it is
appended to the file `$HOME/nohup.out'.  If that cannot be written to,
the command is not run.  If standard output is not a terminal, then the
standard output of COMMAND will be the same as that of `nohup'.
