Calling all Unix Gurus: Shell Scripting Query

[Vasishta.Sushant]

Assume that I've created a lot of variables like
test_1_1=11,
test_1_2=12,
test_1_3=13,
test_2_1=21,
test_2_2=22,
test_2_3=23,
test_3_1=31 and so on.

Can someone help me write a simple multilevel loop to print these variables ?

something on the lines
do i=1 to 10;
.......do j=1 to 10;
............print <the value of test__<j>
......done
done

BTW I am using Korn Shell.

I think you need to convert these variables into a single Multidimensional Array. now, I haven't worked on ksh, so not sure if it support that but you can also use awk to do that.

there u go

#!/bin/ksh
test_1_1=11
test_1_2=12
test_1_3=13
test_2_1=21
test_2_2=22
test_2_3=23
for i in {1..2}
do
        for j in {1..3}
        do
                eval myVal=\${test_${i}_${j}}
                print "test_${i}_${j} = ${myVal}"
        done
done

There you go my man !

I was able to figure that out but this thing surely helped to validate. Thanks a lot for this help. Repped.
