I have file a and file lookup and the structure is below.
vi a.txt
empid|ename|sal_grade|MANAGER_ID
1|raj|A|202
2|MAN|B|203
3|JOS|C|204
vi lookup.txt
Grade|sal|manager_id
A|$100000|202
A|$1000|099
B|$1000000|203
B|$100|011
Output:
1|raj|A|202
2|MAN|B|203
command:
awk 'BEGIN " NR==FNRa[$1];next $3 in aprint $0' lookup.txt a.txt >matched.txt
Here in the both files grade and manager_id is common and i want to join a.txt with lookup.txt on grade and manager_id and get the data out from a.txt where it got a match from lookup.txt .I tried with below command but it will join only on column i.e on grade column but i need to join on both grade and manager id column .
Thank's in advance.

If you need a combined key, build a combined key.
awk '
BEGIN "
NR==FNR a[$1 "-" $3]; next
($3 "-" $4) in a print $0
' lookup.txt a.txt > matched.txt
You can use "-" as a separator, or another string, or nothing at all. With the data from your example it would work without a separator.
