Cannot export some shell variables

Cannot export some shell variables

[Vincent Stemen]

Hi.

Some shell variables do not seem to export to child shells.  Two
variable names I know of so far are $y and $r.  Is there something
special about certain variable names that could cause this behavior?

For example:

# export x=1 y=2 z=3 q=4 r=5
# env
...
SAVEHIST=500
DIRSTACKSIZE=8
x=1
y=2
z=3
q=4
r=5

# zsh
# env
...
SAVEHIST=500
DIRSTACKSIZE=8
x=1
z=3
q=4

As you can see, they are all in the environment before running a child
shell.

I unset all shell options to make sure no options were somehow causing
it (That one has gotten me several times before) but it did not make
any difference.

I tested under two different releases of zsh on two different
platforms:
  zsh 4.2.1 (i386--netbsdelf)
  zsh 4.2.0 (i386-unknown-freebsd5.2.1)

and got the same result.  It also does the same thing if I use the
allexport option rather than exporting them individually.

I also did the same test under both sh and bash and did not have that
problem.

Any ideas?

    Not that I know of. Maybe your rc files are doing something
weird?

    Same commands here and I didn't got that output. My 'env' showed
the same list of vars the two times, running 4.2.5. Maybe you hit a
bug in an older version :?????

Yes, you are right!  It was a dumb user malfunction on my part. I
tested today running zsh with "-f" so it would not run the rc scripts
and it worked properly.  I had forgotten that I was using $r and $y in
my zshrc script and then unsetting them before exiting.  I don't know
why I did not think to check that last night.  I think part of my
brain had already gone to sleep before I was ready to stop working for
the night.

Thanks for the response.

    Nice :) So it is solved. This have hit me a couple of times,
that's why I suggested.
