读取输入文件并将文本插入输出文件

Question

我有一个名为 "namelist.txt" 的输入文件，其中包含电子邮件地址：

user1@domain.com
user2@domain.com
user3@domain.com

我正在尝试从此输入文件中读取地址并将它们的值插入输出文件 (newfile.txt) 中，该文件应为：

user "user1@domain.com" with pass"pass" is "user1@domain.com" here
user "user2@domain.com" with pass"pass" is "user2@domain.com" here
user "user3@domain.com" with pass"pass" is "user3@domain.com" here

我最接近的是使用 awk:

awk '{print "user [=12=] there with pass"pass" is user [=12=] here"}' < namelist.txt > newfile.txt

然而，这会打印以下内容：

user [=13=] there with pass is user [=13=] here 
user [=13=] there with pass is user [=13=] here
user [=13=] there with pass is user [=13=] here

这不会打印变量值和 "pass" 值。

我不知道我哪里出错了，也不知道我是否在正确的轨道上，所以任何建议和/或指示将不胜感激。

编辑：

使用：

awk '{print "user \""[=14=]"\" there with pass \"pass\" is user \""[=14=]"\" here}' file

在 Ubuntu (14.04.2 LTS) 上产生以下输出：

" heree with pass "pass" is user"user1@domain.com
" heree with pass "pass" 是用户 "user2@domain.com
" heree with pass "pass" 是用户 "user3@domain.com

上述代码在 UNIX 终端中运行良好，但在 Ubuntu 和 Raspberry Pi.

中均无效

我对发行版之间的差异感到困惑。

Answer 1

$ 变量需要在引号之外，您需要转义要查看的引号。

awk '{print "user \""[=10=]"\" there with pass\"pass\" is user \""[=10=]"\" here"}' file

user "user1@domain.com" there with pass"pass" is user "user1@domain.com" here
user "user2@domain.com" there with pass"pass" is user "user2@domain.com" here
user "user3@domain.com" there with pass"pass" is user "user3@domain.com" here

Answer 2

您已将文本 [=11=] 包含在文字字符串中，但在任何情况下，当将输入数据插入某些格式化字符串以进行输出时，如果您使用 printf 而不是 print:

$ awk '{printf "user \"%s\" there with pass \"pass\" is user \"%s\" here\n", [=10=], [=10=]}' file
user "user1@domain.com" there with pass "pass" is user "user1@domain.com" here
user "user2@domain.com" there with pass "pass" is user "user2@domain.com" here
user "user3@domain.com" there with pass "pass" is user "user3@domain.com" here

并且不要将输入重定向与 awk 一起使用，因为这会删除脚本访问输入文件名的能力。 awk 完全可以自己打开文件。
