shell question on exporting arrays

c_51 — Tue, 05 Oct 2004 10:25:13 GMT

here is the set up

set -A ab 1 2 3
export ab
typeset -x | grep ^ab

file1:
print ${ab[@]}

file2:
#!/usr/bin/ksh
print ${ab[@]}

the question is, why is the output from
the two files different

and how can I get file2's output to look like file1's

a little more information

I'm using the ksh shell for all of this and
/usr/bin/ksh ./file1 gives the same output
as file2 also.

Hi,

From the man page of "ksh".

//
The export built-in command does not handle arrays properly. Only the
first element of an array is exported to the environment.//

Either you have to run file2 with a . (like . ./file2) or declare your arrays within file2 or put the array in a file (say arrays.rc and call it from file2 like . /whereever/arrays.rc)
