Hi a previously working zsh script
#!/bin/zsh
echo $SHELL
dirbackup="c:/backup/mysql/"
mysqldump="/c/mysql41/bin/mysqldump"
param="--add-drop-table "
server="www.someurl.co.uk"
someurl=(database login password filename)
"$mysqldump" $param -h $server -u${someurl[1]} -p$someurl[2] -B ${someurl
[0]} > ${someurl[3]}.sql
What is happening is that ${someurl[1]} $someurl[2] ${someurl[0]}
are all evaulating to the same value (first element in array)
zsh 4.3.2 (i686-pc-cygwin)
what daft thing am i doing?

Hi
Started new shell and problem went away, but arrays now seem to be
indexed from 1 rather than zero??
Did this change recently?

>From zshparam(1):
Individual elements of an array may be selected using a subscript. A
subscript of the form `[exp]' selects the single element exp, where exp
is an arithmetic expression which will be subject to arithmetic expan-
sion as if it were surrounded by `$((...))'. The elements are numbered
beginning with 1, unless the KSH_ARRAYS option is set in which case
they are numbered from zero.
And this has, as far as I know, always been the case.

Are you running this stand-alone or is it loaded as a shell function?
Did you update any any other part of Cygwin recently?

I'm going to assume the space before [0] is a line wrapping artifact.

Quite frankly I'm not sure how this ever worked. With the ksh_arrays
option NOT set, ${someurl[1]} and ${someurl[0]} should always have been
the same value, and WITH ksh_arrays set, $someurl[2] is the same as
${someurl}[2] which would be interpreted as a file pattern (and either
error with "no match" or result in one of "database[2]" or nothing,
depending on the nomatch and nullglob options).
There is no case I know of where [[ ${someurl[1]} == $someurl[2] ]]
would be true, given the shown starting state of the array.

I can't think of any combination of setopts that would produce your
desired effect with that assortment of subscripting and braces.

As Nikolai said, no, it did not. Aside from the impossible scripting
above, could it be that someone has changed something in a startup file?
Perhaps in the Cygwin equivalent of /etc/zshenv or similar?
