Answer 1

关注awk可能对您有帮助。

awk '
function check(word){
  match($0,word);
  if(substr($0,RSTART,RLENGTH)){
    return substr($0,RSTART,RLENGTH)
}}
{
  val=check("KOREA");
  val=val?$1 FS val FS check("OTL"):check("OTL")?$1 FS check("OTL"):check("OTL");
  if(val){
    print val};
  val=""
}'   Input_file

Answer 2

$ cat infile
11:00:00 INFO KOREA AAABB DDDRR
11:00:01 INFO SWEDEN TYTY PLO
11:00:02 INFO US OIILL OTLTOL
11:00:03 INFO NORTHKOREA OTL

$ awk -v search='KOREA|OTL' '{f=$1; s="";while(match($0,search)){s=(s?s OFS:"") substr($0,RSTART,RLENGTH);$0=substr($0,RSTART+RLENGTH)}if(s)print f,s}' infile
11:00:00 KOREA
11:00:02 OTL
11:00:03 KOREA OTL

更好的可读性：

awk -v search='KOREA|OTL' '{
            f=$1; 
            s="";
            while(match($0,search))
            {
                s  = (s?s OFS:"") substr($0,RSTART,RLENGTH);
                $0 = substr($0,RSTART+RLENGTH)
            }
            if(s)
               print f,s
            }
            ' infile
