赋予脚本执行权限

chmod +x delete restoreTrash logTrashDir cleanTrashCan

delete脚本执行过程

回收站目录

生成.log记录

restoreTrash 脚本执行过程

最后再用systemd/Timers定期每星期日下午六点执行cleanTrashCan脚本 首先编辑

/etc/systemd/system/cleanTrash.service

[Unit]Description=Clean Trash Can[Service]Type=simpleExecStart=/bin/cleanTrashCan

再编辑

/etc/systemd/system/cleanTrash.timer

[Unit]Description=Runs cleanTrashCan every week[Timer]OnCalendar=Sun, 18:00Unit=cleanTrash.service[Install]WantedBy=multi-user.target

执行

systemctl start cleanTrash.timersystemctl enable cleanTrash.timer
