Substring and Join

Experts,

Im struggling with something for the past hour or so and here is the challenge.

File1:
DO93948388 LDCNND 343 48848 -- Row1
DKKDF9933433 DKK 3384774 DLLFLFD -- Row2
DKKFJ38383734 DJF934988 REPFD FD -- Row3


File2:
LDCNNDDKJF --- Row1
DNCNDNCND --- Row2
UFUUOP383 --- Row3
DLLFLFDKDKF63 --- Row4
DJF9349883477 --- Row5


File3(Output):
DO93948388 LDCNND LDCNNDDKJF
DKKDF9933433 DLLFLFD DLLFLFDKDKF63
DKKFJ38383734 DJF934988 DJF9349883477

In the above scenario, in File1, either Col2 or Col3 or Col4 might be a substring in File2's Column1 and if it is, then please fetch the matching Row from File 1 & File2 as shown above in File3.

In sql, we would probably code the above as something like this ...
instr( file2.col1, file1.col2) > 0 or
instr(file2.col1, file1.col3 ) > 0 or
instr(file2.col1, file1.col4) > 0.

Im not sure as how to go about this in unix.

Please help.
Lee.

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons SYNOPSIS
These shell scripts reside in the following directory: /usr/lib/uucp DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file. This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com- mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script. FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file. RELATED INFORMATION
Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1) Files: /usr/lib/uucp delim off uudemon(4)
