manipulate path variable in a shell script?

Hi,

I wanna add a element to my $PATH and remove it later on. So I think
I can write two shell script to do the adding and removing, but you
know, any "export" statement executed in a shell script will take no
effect on current shell. So my script will not be of use. So, how do
I do?

Thanks.

Source your scripts in the current shell using the '.' command.
For example:

$ . add2path

Or have the script/program write shell commands as output, and use
eval,
e.g.:
eval `my_program`
