如何将多个字段分配给变量？

Question

我想使用awk 1liner

将data.txt文件转换为以下输出

cat data.txt

  

  
• personA neta netb netc
  
• personB meta metb metc metd
  

...

输出：

• personA在他的包中有{neta netb netc}项目
• personB在他的包中有{meta metb metc metd}项目

Answer 1

这对subtr（）和index（）很有用。

awk '{print $1FS"has {"substr($0,index($0,$2))"} itmes in his bag."}' data.txt

输出：

  

personA在他的包里有{neta netb netc} itmes。

     

personB在他的包里有{meta metb metc metd} itmes。

Answer 2

awk '{$1=$1" has";$2="{"$2;print $0"} items in his bag"}' data.txt

Answer 3

while read line; do
  set -- $line
  person=$1
  shift
  printf "%s has {$s} items in his bag" "$person" "$*"
done < data.txt

Answer 4

怎么样：

awk '{ items=""; 
       for(i=2;i<=NF;i++) {items=items" "$i}; 
       gsub(/^[ ]/, "", items);
       print $1" has {"items"} items in his bag" }' data.txt
