Sorry folks, I'm explaining this really badly. Forget I said anything
about bash. I don't care about bash. I'm trying to leave bash behind.
Let me start over. Here's what happens in zsh 4.3.11
# my comments are offset with #
# fyi - "Air%" is my prompt
# just to show that $NAME is empty
Air% echo $NAME
Air%
# /tmp/.source has only one line:
Air% cat /tmp/.source
NAME=`basename $0`
# here is my 'test.zsh' script:
Air% cat ./test.zsh
#!/bin/zsh
. /tmp/.source
echo "$NAME"
exit 0
# So now I run 'test.zsh' :
Air% ./test.zsh
.source
# OK, so you can see that it output '.source' when I wanted it to
output 'test.zsh'
# Next: rename /tmp/.source to ~/.zshenv
Air% mv /tmp/.source ~/.zshenv
# Edited 'test.zsh' is now this:
Air% cat =test.zsh
#!/bin/zsh
echo "$NAME"
exit 0
#EOF
# now when I run 'test.zsh' again:
Air% test.zsh
zsh
# Someone suggested "unsetopt function_argzero" so I added that to .zshenv:
Air% cat ~/.zshenv
unsetopt function_argzero
NAME=`basename $0`
# and re-ran test.zsh, which gave me:
zsh
Is it even possible to set NAME in .zsh* (and have it return
'test.zsh' or are they called too early in the process?
