使用mailx和bash脚本parsing邮件正文

如果这是通过类似sendmail的MTA将邮件传递到本地用户帐户，那么可以使用procmail来解析正在传递的电子邮件。

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' ############################################################################# # if the email comes from the client with a specific Subject, # send a copy of the message to the processing script, and # carry on with the next recipe :0c * ^From:.*@clientdomain\.invalid * ^Subject:.*Account.*(Request|Access|Approval) | $HOME/bin/process_account_request_email.pl | \ mailx -s "Account request results" $MY_RECIPIENT ############################################################################# # forward all mail to mailing list :0 * ! ^$MY_XLOOP { # add a header # 'f' = filter: pass message to program and continue processing results # 'h' = pass message headers to program # '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 

在procmail包中的formail可以很好的完成这个工作，正如另一个答案中所述，但是这里是我认为这个问题的直接答案的一个总结：

 $ 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"
