Hi,
It's Working fine at my end.

Code:

# cat aa.txt
"this is the line1"=line one found
"this is the line2"=line two found

Code:

# cat bb.txt
"This is a test message which contains rubbish information just to fill the page which is of no use.
 this is the line1 which is suppose to be grepped and displayed as a output.
this is the line2 with specific pattern AABCDEFGHI which is to be grepped"

Code:

# awk -F"[\"=]" 'NR==FNR{a[$2]=$4;next} {for(i=1;i<=NF;i++) {if($i ~ /^AA/ && length($i)==10) {print FNR" : "$i;next}}} {for (j in a){if($0 ~ j){print FNR" : "a[j]}}}' aa.txt FS=" " bb.txt

O/P

Code:

2 : line one found
3 : AABCDEFGHI
