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.

gzexe

GZEXE(1)						      General Commands Manual							  GZEXE(1)

NAME

       gzexe - compress executable files in place

SYNOPSIS

       gzexe [ name ...  ]

DESCRIPTION

       The  gzexe  utility  allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
       penalty in performance).  For example if you execute ``gzexe /bin/cat'' it will create the following two files:
	   -r-xr-xr-x  1 root  bin   9644 Feb 11 11:16 /bin/cat
	   -r-xr-xr-x  1 bin   bin  24576 Nov 23 13:21 /bin/cat~
       /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file.  You can remove /bin/cat~ once  you  are	sure  that
       /bin/cat works properly.

       This utility is most useful on systems with very small disks.

OPTIONS

       -d     Decompress the given executables instead of compressing them.

SEE ALSO

       gzip(1), gznew(1), gzmore(1), gzcmp(1), gzforce(1)

CAVEATS

       The  compressed	executable  is a shell script. This may create some security holes. In particular, the compressed executable relies on the
       PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).

BUGS

       gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually  in  some  cases,
       using chmod or chown.
