使用awk计算多列中的字数

Question

输入文件（制表符分隔）

1 . Hello World . 51.4 . This is a text . 200
2 . Another line . 16.4 . Some more words . 600

所需输出（制表符分隔）

Hello World . 2 . This is a text . 4 
Another line . 2 . Some more words . 3

输出是第2列和第4列，它们的字数

我已经

了

awk '{print $2, "\t", NF}' > output.tsv

但不知道如何在单个命令中为多个列执行此操作

Answer 1

awk救援！

awk 'BEGIN {FS=OFS="\t"} 
           {print $2,split($2,x," +"),$4,split($4,x," +")}' file

Hello World     2   This is a text  4
Another line    2   Some more words 3
