`export'
The builtin `export' dubs a shell variable "environment variable".
Each update of exported variables corresponds to an update of the
environment variables. Conversely, each environment variable
received by the shell when it is launched should be imported as a
shell variable marked as exported.
Alas, many shells, such as Solaris 2.5, IRIX 6.3, IRIX 5.2, AIX
4.1.5, and Digital UNIX 4.0, forget to `export' the environment
variables they receive. As a result, two variables coexist: the
environment variable and the shell variable. The following code
demonstrates this failure:
#! /bin/sh
echo $FOO
FOO=bar
echo $FOO
exec /bin/sh $0
when run with `FOO=foo' in the environment, these shells will print
alternately `foo' and `bar', although it should only print `foo'
and then a sequence of `bar's.
Therefore you should `export' again each environment variable that
you update.
