我正在尝试使用电子邮件自动化我的某些工作。是否有任何方法可以使用 mailx 和 bash 来提取邮件正文？

formailprocmail正如另一个答案中所述，从包装中可以很好地完成工作，但这里是我认为是该问题的直接答案的摘要：

$ sudo apt-get install procmail

$ cat test.eml | formail -x To
 test@mydomain.com

$ cat test.eml | formail -x Subject
 hello

$ cat test.eml | formail -x Content
 multipart/alternative; boundary="f403043eea78e8658a0554677278"

如果这是通过类似 sendmail 的 MTA 发送到本地用户帐户的邮件，那么您可以使用procmail在发送电子邮件时对其进行解析。

在我使用的系统上，sendmail 会检查~/.forward文件，所以我在 ~username/.forward

# pipe incoming mail to procmail
# ref: http://www.panix.com/~elflord/unix/procmail.html
# ref: http://porkmail.org/era/procmail/mini-faq.html#forward
"|IFS=' ' && p=/usr/local/bin/procmail && test -x $p && exec $p -f- || exit 75 #username"

然后，~username/.procmailrc包含：

# procmail tutorial: http://tldp.org/LDP/LG/issue14/procmail.html

PATH=/usr/local/bin:/bin:/usr/bin
MAILDIR=$HOME/Mail
DEFAULT=$HOME/Mail/inbox
LOGFILE=$HOME/procmail.`date +%Y-%m`.log
SHELL=/usr/bin/ksh

MY_XLOOP='X-Loop: username@hostname.subdomain.example.com'
MY_RECIPIENT='mailing.list@example.com'

    # 'w' = wait for program to return
    :0fhw
    | formail -A "$MY_XLOOP"

    # then forward the message
    # 'c' = send a copy to recipient and continue processing
    :0c
    ! $MY_RECIPIENT
}

# if we get here, then the message has an X-Loop header.
# let it fall into $DEFAULT
