awk 根据模式转置行并在填充空字段的当前列之前移动（复制）

Question

您好，我正在尝试使用以下格式的文本

输入：

NICK JEFF
NOAA A4:80:15
NOAA A4:80:17
NOOI D0:F2:0B BASE-TREE_IN-M_K
NICK STAN
NOAA C1:46:6B
NOOI D5:75:0C BASE-TREE_OUT_OUT
NICK INDEXER
NOOI D5:75:0C SEAT_25
NOAA C1:46:6B
NICK VUZER
NOAA A4:F2:CD
NOOI D0:F2:2D SEAT_42_FLIGHT
NOAA A4:F2:CD
NICK CAPTAIN
NOOI A4:82:8D
NOAA A4:82:8F
NOOI 40:63:07 SYS-BRAVO_X1
NOOI 40:62:DB SYS-BRAVO_X2
NOOI 40:62:B5 SYS-BRAVO_X3
NOOI D0:47:4A BASE-TREE_OUT_OUT
NOOI 51:30:45 NOBASE-INDEX_OUT_FIF
NOOI A4:82:8D
NOAA A4:82:8F

我试过这个，但它错误地复制了我的值

awk '{for (i=1; i<=1; i++) { print $i " " " "" "}}' input

预期的输出应该像下面这样整理：

NICK JEFF NOAA A4:80:15 EMPTY
NICK JEFF NOAA A4:80:17 EMPTY
NICK JEFF NOOI D0:F2:0B BASE-TREE_IN-M_K
NICK STAN NOAA C1:46:6B EMPTY
NICK STAN NOOI D5:75:0C BASE-TREE_OUT_OUT
NICK INDEXER NOOI D5:75:0C SEAT_25
NICK INDEXER NOAA C1:46:6B EMPTY
NICK VUZER NOAA A4:F2:CD EMPTY
NICK VUZER NOOI D0:F2:2D SEAT_42_FLIGHT
NICK VUZER NOAA A4:F2:CD EMPTY
NICK CAPTAIN NOOI A4:82:8D EMPTY
NICK CAPTAIN NOAA A4:82:8F EMPTY
NICK CAPTAIN NOOI 40:63:07 SYS-BRAVO_X1
NICK CAPTAIN NOOI 40:62:DB SYS-BRAVO_X2
NICK CAPTAIN NOOI 40:62:B5 SYS-BRAVO_X3
NICK CAPTAIN NOOI D0:47:4A BASE-TREE_OUT_OUT
NICK CAPTAIN NOOI 51:30:45 NOBASE-INDEX_OUT_FIF
NICK CAPTAIN NOOI A4:82:8D EMPTY
NICK CAPTAIN NOAA A4:82:8F EMPTY

这意味着模式一直是"nick"并且输入文件的文件读取方向是从上到下并且像jeff stan等昵称被放置（复制）在它意味着它设置为第一个之前并且第二列后面是输入的前几列。文本 "EMPTY" 被添加到空字段以保留 format/to 具有相等的列/字段数字填充值

我想这就是你需要的

$ awk '/^NICK/ {p=[=10=]; next} 
               {print p,[=10=],(NF>2?"":"EMPTY")}' file

NICK JEFF NOAA A4:80:15 EMPTY
NICK JEFF NOAA A4:80:17 EMPTY
NICK JEFF NOOI D0:F2:0B BASE-TREE_IN-M_K 
NICK STAN NOAA C1:46:6B EMPTY
NICK STAN NOOI D5:75:0C BASE-TREE_OUT_OUT 
NICK INDEXER NOOI D5:75:0C SEAT_25 
NICK INDEXER NOAA C1:46:6B EMPTY
NICK VUZER NOAA A4:F2:CD EMPTY
NICK VUZER NOOI D0:F2:2D SEAT_42_FLIGHT 
NICK VUZER NOAA A4:F2:CD EMPTY
NICK CAPTAIN NOOI A4:82:8D EMPTY
NICK CAPTAIN NOAA A4:82:8F EMPTY
NICK CAPTAIN NOOI 40:63:07 SYS-BRAVO_X1 
NICK CAPTAIN NOOI 40:62:DB SYS-BRAVO_X2 
NICK CAPTAIN NOOI 40:62:B5 SYS-BRAVO_X3 
NICK CAPTAIN NOOI D0:47:4A BASE-TREE_OUT_OUT 
NICK CAPTAIN NOOI 51:30:45 NOBASE-INDEX_OUT_FIF 
NICK CAPTAIN NOOI A4:82:8D EMPTY
NICK CAPTAIN NOAA A4:82:8F EMPTY

Answer 2

awk '{if(=="NICK")
        {line=[=10=]}
      else
        {if(NF==2)
           {print line,[=10=],"EMPTY"}
         else
           {print line,[=10=]}
        }
     }' file

输出：

NICK JEFF NOAA A4:80:15 EMPTY
NICK JEFF NOAA A4:80:17 EMPTY
NICK JEFF NOOI D0:F2:0B BASE-TREE_IN-M_K
NICK STAN NOAA C1:46:6B EMPTY
NICK STAN NOOI D5:75:0C BASE-TREE_OUT_OUT
NICK INDEXER NOOI D5:75:0C SEAT_25
