query in using Double Quotes
Hi

i am referring a book for understanding the Double Quotes
book suggest for the below code

Code:
code

echo "$USER owes <-$1250.**>; [ as of (īdate +%m/%dī) ]"
Code:
 the o/p is

Fred owes <-250.**>; [ as of (12/21) ]

however when i ran the same command i got below
Code:
 o/p

iscpadm owes <-250.**>; [ as of (date +%m/%d) ]

need to know why i am not getting the o/p for date part.

using OS AIX
shell is ksh

You are using the wrong quotes. use ` for calculations Smilie

and here
Code:
 $USER owes <-$1250.**>;

the system understands $1 as the 1st parameter being passed to the script. so you have to escape $ by using \ Smilie

Hope this helps
