input.tsv集計短縮され、私は空白のフィールドに上に見られるのと同じ言葉を印刷したいとファイルの最後まで1番目、2番目、3番目の列に適用します。別の言葉が現れたら、下の印刷はこの新しい言葉でなければなりません。出力は次のようになります。

rs928302  YES  TMPRSS3 rf  G  V  53  NM_001256317.1 NP_001243246.1

Unix環境ではどうすればできますか？前もって感謝します。

awk ' 
BEGIN { FS=OFS="\t" } 
{ 
    for (i=1; i<=3; i++) { 
     if ($i == "") { 
      $i = p[i] 
     } 
     else { 
      p[i] = $i 
     } 
    }
