linux操作系统中/var/spool目录下存放的是什么？

谢谢。

/var/spool 存放的是 mail, news,
打印队列和其他队列工作的目录.每个不同的spool在/var/spool 下有自己的子目录，例如，用户的邮箱在/var/spool/mail中。

Answer 3

翻译原文解析应该会更好理解这个假脱机目录的作用.
Linux Filesystem Structure
5.11 /var/spool : Spool directories
/var/spool is traditionally used for machine-local data being spooled to or from UNIX subsystems. For example, print jobs are spooled here for delivery to the lineprinter daemon, out-bound mail is spooled for delivery to remote systems, and UUCP files are spooled for transmission to UUCP neighbors. In-bound mail and news are spooled here for delivery to users, and at and cron jobs are spooled for delayed execution by the cron daemon.
我个人的理解/var/spool的作用和意义是:
本地主机假装已经把mail或者打印内容发送出去,完成任务了.但其实是没有发送出去的,只是存在于/var/spool中等待外部设备比如打印机或者别的邮件服务器来这里取.
