You can do similar things with the set -x option of sh(1):

% gothmog:/tmp$ cat echo.sh
% #!/bin/sh
%
% set -x
% ls /tmp
% set +x
% echo no echo
% ls /tmp
% gothmog:/tmp$ sh echo.sh
% + ls /tmp
% echo.sh         screens         ssh-6OYAaVIB9P
% + set +x
% no echo
% echo.sh         screens         ssh-6OYAaVIB9P
% gothmog:/tmp$

Note how the commands after set -x are echoed.
