Ravi,

user_name=`echo $QUERY_STRING | awk -F"=" '{print $2}'`
Pass_word=`echo $QUERY_STRING1 | awk -F"=" '{print $2}'`

now search for user_name and password in the file as below.

ex: cat reference_file.txt

Name | Gender |Password
rohit|male|xxxx
robin|male|YYY

Code:
 
user_name="robin"
res1=`awk -F "|"  -v var_name=$user_name  '{if ($1==var_name){print "found";exit} }' reference_file.txt`

if res1 is "found" go and search the file again for password validation.
