如何使用linux mail命令在电子邮件中插入新行？

echo "Hi xxx, would you tell me something?\\n thanks!\\n -xxx" | mail -s "subject" [e-mail]

The email shows the literal '\n', not a newline, how do fix it?

电子邮件显示字面'\ n'，而不是换行符，如何解决？

4 个解决方案

#1

Try using echo -e

尝试使用echo -e

echo -e "Hello \n World"

echo -e“Hello \ n World”

You can type man echo from the command line to read more.

您可以从命令行键入man echo以阅读更多内容。

#2

With mailx, if you send the email to oultook user, you can add 2 spaces at the begenig of each line.

使用mailx，如果您将电子邮件发送给oultook用户，则可以在每行的begenig中添加2个空格。

{ echo "Hi xxx, would you tell me something" ; echo "thanks!" ; echo "-xxx" } | sed 's/^/  /g' | mailx -s "subject" [e-mail]

#3

I encountered this issue and resolved it by surrounding with quotes the variable I was piping into mailx.

我遇到了这个问题并通过用引号括起来解决了这个问题。

I started with a list of processes from ps i.e. list="$(ps |grep some_process)".

我从ps开始了一个进程列表，即list =“$（ps | grep some_process）”。

Then when I tried to mail that out as follows, the newlines were obliterated:

然后，当我尝试按如下方式邮寄时，新线被删除：

echo $body | mailx -s "${subject}" [e-mail]

But, simply wrapping $body with quotes preserved the newlines:

但是，简单地用引号括起$ body保留了换行符：

echo "$body" | mailx -s "${subject}" [e-mail]
