Works here:

$ echo $TEST

$ ls -l bla.sh
-rw-r--r--  1 stijn  stijn  32 Jun 28 16:39 bla.sh
$ cat bla.sh
TEST=test; export TEST
echo dsa
$ . bla.sh
dsa
$ echo $TEST
test

but only in sh - use 'source' for csh/tcsh (and make sure your
script is written in the syntax for those shells!)

As to why this works, that's because this command executes all
commands listed in the file as if you had typed them in; that
is, it doesn't spawn a subshell. So, you modify your login shell's
environment (which is what you wanted).

Thank you Alex for the suggestion - I didn't think of it before.
