Hi,
the env program does not quote the output by default and there is no
way to tell the program to do so. This makes the program quite a bit
dangerous. It is possible to define a value of an environment
variable with a newline:
$ export EVIL='
> FAKE=1'
The output of the env program makes it impossible to distinguish
between real variables and faked variables:
$ env
...
EVIL=
FAKE=1
...
Does POSIX require this behavior?
bis später...
