Shell Programming and Scripting

Hi All
I have a file containing the following information

SOURCESERVER DESTINATIONSERVER DESTINATIONENVIRONMENT CONDITION
I was trying to read and then execute the conditions,like if SOURCESERVER is XXXX0001 and the DESTINATIONSERVER is XXXX0002 and the DESTINATIONENV is YYY the conditions: 1 or 2 or 3.

can you guys pls tell me as how to proceed as i used the following code and its not working
exec 1 <filename.txt
while read -u1 SCRSERV DESTSERV DESTENV CONDITION
do
echo $SCRSERV
$ DESTSERV
$ DESTENV
$ CONDITION
done

Code:

#!/bin/ksh
while read SCRSERV DESTSERV DESTENV CONDITION
do
  if [ "${SCRSERV}"   = "XXXX0001" -a \
       "${DESTSERV}" = "XXXX0002" -a \
       "${DESTENV}"   = "YYY" ]; then
    if [ "${CONDITION}" = "1" -o \
         "${CONDITION}" = "2" -o \
         "${CONDITION}" = "3" ]; then
      echo "FOUND"
    fi
  fi
done < input_file

alternatively , you can use the case structure also.

Hi Shell life and Kamitsin
thnks for the code,i think i didn't explain you guys my problem.The problem is i cannot hardcode it,it must be generic and see the example below:
ENV1|XXXX.c01.company.com (ENV2)|3

the frst field is the source environment,the second field is the destinationserver name and the (ENV2) is the destination environment and the third field #3 indicates the condition:
1=standard path
2=alternate path
3=prohibited path
so,i have 7 environments,so the code must be generic and not specifc to any single environment,hopefully you guys got it.

thnks in advance
