sudoers 文件不支持基于时间的限制,但有一个简单的方法。创建一个包含您在/etc/sudoers.d/(with sudo visudo -f /etc/sudoers.d/yourfile) 中的更改的文件:
file.sh将以下内容添加到文件(例如:)
mv /etc/sudoers.d/yourfile /etc/sudoers.d/.yourfile

在这种情况下,它会在您发出命令 2 天后的下午 2 点移动文件。该at 手册有一些选项(您可以使用时间、天、周、月、年、下一个或添加/减去周期等关键字)。使用选项进行一些测试以确保您理解它(需要考虑的事项:如果您at在当天下午 2 点之前或之后开始,这很重要。)
at也可以在重启后幸存下来,因此是用于此类事情的好工具。你可以切换访问...
sudo mv /etc/sudoers.d/.yourfile /etc/sudoers.d/yourfile | at 2pm + 2 days
sudo mv /etc/sudoers.d/yourfile /etc/sudoers.d/.yourfile | at 2pm + 4 days
sudo mv /etc/sudoers.d/.yourfile /etc/sudoers.d/yourfile | at 2pm + 6 days
sudo mv /etc/sudoers.d/yourfile /etc/sudoers.d/.yourfile | at 2pm + 8 days

并让该用户发疯(wtf 现在我可以做到这一点)。
中的自述文件/etc/sudoers/:
# As of Debian version 1.7.2p1-1, the default /etc/sudoers file created on
# installation of the package now includes the directive:
#
# #includedir /etc/sudoers.d
#
# This will cause sudo to read and parse any files in the /etc/sudoers.d
# directory that do not end in '~' or contain a '.' character.
#
# Note that there must be at least one file in the sudoers.d directory (this
# one will do), and all files in this directory should be mode 0440.
#
# Note also, that because sudoers contents can vary widely, no attempt is
# made to add this directive to existing sudoers files on upgrade. Feel free
# to add the above directive to the end of your /etc/sudoers file to enable
# this functionality for existing installations if you wish!
#
# Finally, please note that using the visudo command is the recommended way
# to update sudoers content, since it protects against many failure modes.
# See the man page for visudo for more information.

如果我正确阅读了它,它将不会执行任何带有“.”的文件。名字中的任何地方。所以第一个mv命令我放置了“。” 在前面使它也看不见。如果正确假设,您可以放置一个“。” 任何地方。小心“~”,它被 gEdit 等编辑器用作“备份”功能。
at默认情况下未安装。安装
sudo apt-get install at
