单行 Linux/bash 打印复杂语句

Question

我有一个包含两列数据的文件，让我们说：

kevin n1

edwin n2

mevin n3

我想用这样的东西生成一个声明。

--This is kevin and his 'roll number' is n1

--This is edwin and his 'roll number' is n2

--This is mewin and his 'roll number' is n3

现在，我无法使用awk. 它不喜欢语句中间的破折号“--”或单引号 (')。

我希望输出按照我上面显示的方式输出？

Answer 1

使用 awk：

awk 'NF{print "--This is " $1 " and his \047roll number\047 is " $2 }' file

\047是单引号的八进制代码'。

另一种选择是定义一个包含单引号字符的变量：

awk -v sq="'" 'NF{print "--This is " $1 " and his "sq"roll number"sq" is " $2 }' file
