如何通过邮件从shell脚本发送特殊字符？ [英] How to send special characters via mail from a shell script?

问题描述

我有一个脚本，运行在cron上，输出一些我们发送到'mail'程序的文本。一般行如下：

  ./ command.sh | mail -s我的主题[e-mail]  -  -F发件人姓名-f [e-mail] 
  

问题是脚本生成的文本有一些特殊字符 - é，ã，ç - 因为它不是英文。收到电子邮件后，每个字符都被替换为。

现在我明白，这很可能是因为编码设置不正确。

解决方案

我的 / usr / bin / mail 符号链接到 / etc / alternatives / mail ，它也符号链接到 / usr / bin / bsd-mailx

我必须在邮件头中指定自己的编码。 （ -S 不支持。）

cat myutf8-file | mail -aContent-Type：text / plain; charset = UTF-8-s我的主题[e-mail]

I have a script that runs on cron that outputs some text which we send to the 'mail' program. The general line is like this:

./command.sh | mail -s "My Subject" [e-mail] -- -F "Sender Name" -f [e-mail]

The problem is that the text generated by the script has some special characters - é, ã, ç - since it is not in english. When the e-mail is received, each character is replaced by ??.

Now I understand that this is most likely due to the encoding that is not set correctly. What is the easiest way to fix this?

解决方案

My /usr/bin/mail is symlinked to /etc/alternatives/mail which is also symlinked to /usr/bin/bsd-mailx

I had to specify myself the encoding in the mail header. (The -S is not supported here.)

cat myutf8-file | mail -a "Content-Type: text/plain; charset=UTF-8" -s "My Subject" [e-mail]
