赋予脚本执行权限
|
1 |
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
|
1 |
/etc/systemd/system/cleanTrash.service |
|
1 2 3 4 5 6 |
[Unit] Description=Clean Trash Can [Service] Type=simple ExecStart=/bin/cleanTrashCan |
再编辑
|
1 |
/etc/systemd/system/cleanTrash.timer |
|
1 2 3 4 5 6 7 8 9 |
[Unit] Description=Runs cleanTrashCan every week [Timer] OnCalendar=Sun, 18:00 Unit=cleanTrash.service [Install] WantedBy=multi-user.target |
执行
