Python使用Gmail发邮件详解编程语言

有时候需要备份些东西到邮箱，能够让脚本定时自动运行当然是最好！ 抽时间用python写了这么个脚本，使用python-libgmail库 ( sudo apt-get install python-libgmail )

需求

发送邮件的代码都是现成的调用，主要是在易用性上做了些优化：

1、发送一句话，不需要正文，比如给邮件列表发个“求助。。。。。（如题）”之类的：

 msend -t  [email protected] -s "求助，图形界面进不了，哈哈”

2、发个文件到自已的邮箱,一般用 -f “file1;file2;file3;dir2;dir3” ，发懒的时候不写 -f 也能用

 msend -t [email protected] -f readme.txt 
    msend -t [email protected] *.txt

3、发个文件或目录到某个邮箱，需要ZIP一下,(当然2和3可以混用)

 msend -t [email protected] -z ./pics/

基本上：

1、目标邮箱和主题必须写上； 2、如果有文件附件，可以不指定主题，脚本会把文件数当主题名(gmail的title里会显示正文的) 3、程序会自动判断文件和目录，如果是目录就会遍历 4、不管是文件还是目录，如果前缀指定了-z，就压缩后发送 5、没有前缀的参数一律当文件名 如果有需要，可以下载玩玩，运行msend不带参数就有用法，应该很明白了。

（还有什么稀奇古怪的想法？欢迎提出来！）

    Usage: 
        msend -t [email protected] -s title 
        msend -t [email protected] {-s title | -f file | -z file} 
 
    Full command: 
        msend [email protected] --subject=title [--msg=body] [--files="file1;dir2"] [--zip="file1;dir2"] 
 
    Example: ( edit ~/.msend for default sender account ) 
        msend -t [email protected] -s "just a test" 
        msend -t [email protected] -s "send all pic" -f ./mypics/ 
        msend -t [email protected] -s "send files as zip" -z ./mytext/ 
        msend -t [email protected] -s "send both" -f mytext -z mytext
