Hi,
I'm not sure this answer suits to your request (if you meant
"how to display/store or use the resulting value", then this
should help...).
First, the 2 first lines sound correct for both defining a variable
and assigning a value to it:
me@host> A="PRE"
me@host> eval ${A}_DAY=`date +%d`
In order to solve this kind of trouble, I usually use this
kind of syntax:
me@host> DAY_VALUE=$(unalias echo; eval echo $"${A}_DAY")
me@host> echo ${DAY_VALUE}
me@host> 25
Hope it helps,
Christophe

Hi,
How can I get this to work?
#!/bin/ksh

cat some_file_name $direction temp.txt
