Thanks to radoulov and Franklin for your replies.

Just to make my requirement simple.

Code:
$ ls /temp
one  three  two

$ cat one
1
2
3

$ cat two
4
5

$ cat three
6
7
8

$ cat comb.sh
for i1 in `cat one`
        do
                for i2 in `cat two`
                        do
                                for i3 in `cat three`
                                        do
                                                echo "$i1|$i2|$i3"
                                        done
                        done
        done

$ ./comb.sh
1|4|6
1|4|7
1|4|8
1|5|6
1|5|7
1|5|8
2|4|6
2|4|7
2|4|8
2|5|6
2|5|7
2|5|8
3|4|6
3|4|7
3|4|8
3|5|6
3|5|7
3|5|8

But above code is hard-coded (I am specifying the file names in the code, I don't want to do that). what I want is that suppose if I add one more file called "four" with entries

Code:
$ cat four
9

Without adding a "for loop" for file "four", it should take automatically:

so that the output becomes:

Code:
1|4|6|9
1|4|7|9
1|4|8|9
1|5|6|9
1|5|7|9
1|5|8|9
2|4|6|9
2|4|7|9
2|4|8|9
2|5|6|9
2|5|7|9
2|5|8|9
3|4|6|9
3|4|7|9
3|4|8|9
3|5|6|9
3|5|7|9
3|5|8|9

i.e. How to construct the above "for loops" automatically based upon the files in /temp;; (Assuming the order of the loops is defined in a separate file)

Code:
$ cat order
one
two
three
four

Apologies for posting a huge query.
