read the lines of multiple files
I am trying to create a script which will read 2 files and use the lines of file 1 for each line on file 2.

here's my sample code

Code:
cat $SBox |
while read line
        do
        cat $Date |
        while read line
        do $SCRIPTEXE <line from first file> $2 <line from 2nd file> 
                done
        done

is this possible in shell scripting?
i am using ksh by the way
Thanks!

I would say yes but what your wrote here will be a nightmare when things go wrong:
How will you distinguish the line variable between the first and the second loop...
Code:
do $SCRIPTEXE <line from first file> $2 <line from 2nd file>

will not work as written here
What is $2?

$2 would be a parameter to be used on the other script which i am trying to call in there

Just to give an idea (no time to test... sorry...)
Code:
#cat $SBox |
while read LINE1 
do
        #cat $Date |
     while read LINE2
     do 
           $SCRIPTEXE $LINE1 $2 $LINE2 
     done <$Date
done <$SBox

Code:
paste -d, file1 file2 | while IFS=, read a b; do yourscript $a $b;done

Or choose a suitable separator instead of coma.
(You may also want to add some $a and / or $b checking enhancement).
