Unix Array Variables

[ezhilarasan_1]

Hi,


I want a simple Unix shell programes to understand unix array variables of character strings and numbers.
(define, setting value, manipulation, and printing).


Thanks
Ezhil

Hi Ezhil:

Perhaps this helps:

#!/usr/bin/sh
echo "Enter a series of space-delimited fields to populate ARY"
read LINE
set -A ARY ${LINE}
echo "${#ARY[*]} elements exist"
echo "element_0 = ${ARY[0]}"
echo "element_1 = ${ARY[1]}"
exit 0

The 'set' declares an array named ARY and populates it with the contents of LINE.

You have knowledge of how many elements exist as shown and how to reference individual elements.

See the manpages for 'sh-posix' for more information, particularly the 'set' statement.

Regards!
