需要重启cups才能访问网络打印机

Question

每隔一段时间（不一定在从挂起或启动恢复后）我必须sudo /etc/init.d/cups restart再次查看网络打印机。有没有办法绕过这个过程，或者在 Lubuntu 16.04 下自动化它的最佳方法是什么？

Answer 1

对于基于 Linux 的 shell 脚本，您可以尝试按如下方式安排脚本：

crontab 条目：

*/5 * * * * sh /scripts/cups_recursive_checking.sh

#/bin/sh
HOST='server-name'

/etc/init.d/cups status>/scripts/cups.txt

if grep "cupsd (pid " /scripts/cups.txt
then
    echo "cups is already running"
    exit
else
    /etc/init.d/cups restart
    echo "cups just now started in server-name"

    ############# For mail Notification whenever cups gets restart follow below line according to your email ##########

    mutt -e "my_hdr Content-Type: text/html" -e 'set realname=Notification' \
                    -e 'set from=notification@your-email.com' user@your-email.com \
                    -s "CUPS Notification" < /scripts/cups.txt
fi
###END OF THE SCRIPT###

示例： 在 Linux 中重启 cups 后检查打印机

lpstat -a
