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:

#####

MC_Addr:

#####

577890

#####

erce_Ban_1:

#####

7455

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

  • I tried this command after putting source file "out" and required numbers in file list "for i in cat list;do if [[ grep -w $i out ]];then grep -w $i out;else echo $i" :not found";fi ;done", but i got no headers.

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:

    You can try something like this:



    awk '{if(match($0,":")) header=$0; if($0 == 2516) printf("%sn%sn",header,$0)}' input_file.txt


    Where "2516" is the number you are searching for.



    obs: I'm assuming that all the labels ends with ":".



    I hope this helps.

    awk approach:



    awk -v RS="#####" -v num=2515 '$0~/[0-9a-zA-Z_]+:/{ 
    
     getline nl; if (nl~num){sub("n", "", $0); printf("%s%dn",$0,num)}}' file


    The output:



    IGHTY_BBBT:
    
2515



    RS="#####" - treating ##### as record separator



    -v num=2515 - a variable containing search number



    $0~/[0-9a-zA-Z_]+:/ - capturing header line



    getline nl - get next record containing numbers



    if (nl~num) - if search number is matched within a line of numbers
