Hi!

the (bash) shell-script

-----
#!/bin/sh
export blubber=blabber

-----

should set the variable blubber to the value blabber in the shell, from
where I call the script...but it DOESN'T...any suggestions?

Thanks in advance,

Holger Hartmann

You can't do it; a shell script cannot effect the environment of a parent.

The 'export' command actually is in the opposite direction to what you
want, marking a variable for export means that the variable will be copied
as part of the default environment for any _child_ shell run.

The only way you can solve this problem directly is to "source" the
script (ie: execute it within the current shell process).

In ksh/bash/sh you want the "." built-in command (man sh),
in csh it's "source".

As Laura said, you can't do it that way, but consider this alternative:

function blubber2blabber {
    export blubber=blabber

Now,

    bash-2.04$ blubber2blabber

will set the exported variable.  functions work in the current
environment, as does dotting a file.
