正则表达式 – 用于翻译由行中的制表符分隔的查找第三个单词的Sh

[somedude@dev7 ~]# cat so.txt 
Hello   how Are You
Iam Fine    how about
[somedude@dev7 ~]#

我跑了：

[somedude@dev7 ~]# cat so.sh 
#!/bin/bash

_INPUT="Hello how Are You
Iam Fine how about"

# read each line from config file
while read -r l 
do

  _GET_THIRD_WORD=$(echo $l | awk '{print $3}')

  echo $_GET_THIRD_WORD | sed -i "s,$_GET_THIRD_WORD,SOMETHINGTOTRANSLATEWITH," 

done < so.txt
[somedude@dev7 ~]#

这将使您的每个翻译行回显到标准输出.

希望这可以帮助！
