I need to search for a string (number here), and print it’s header or title using grep or awk or anything.
please check this example:
Input file content:
##### Production_Broad: ##### 678 544 ##### IGHTY_BBBT: ##### 1666 2515 2516 2517 2518 ##### Jaguar: ##### 280 ##### Loyalty: ##### 5179 ##### MC_Addr: ##### 544 577890 ##### erce_Ban_1: ##### 7455 5656
I want to search for the number “2515”, and it gives me below output:
IGHTY_BBBT: 2515
and if i searched for “5179”, the output should be as below:
Loyalty: 5179
Answer
If headers are identified by those ##### lines, and the list of IDs to search for is in a ids.txt file (one per line), you could do:
awk '
!ids_processed{ids[$0]; next}
$0 == "#####" {getline header; getline; next}
$0 in ids {print header ORS $0}' ids.txt ids_processed=1 input.txt
For instance, if ids.txt contains
2515 544 577890
On your sample, that would give:
Production_Broad: 544 IGHTY_BBBT: 2515 MC_Addr: 544 MC_Addr: 577890
