I have Ubuntu 10.04. Certain operations in the Terminal application or operations require me to type sudo [whatever command]and my password. I have noticed the effects of sudolast for awhile; five minutes or so.

How can I explicitly exit sudoand go back to being me at the command prompt?

sudo -k
Note that you're not running sudoto need to exit it, rather sudo remembers the last time you authenticated and doesn't require re-authentication if that's recent enough. This command will reset timestamp to the epoch. You can change the timeout value in the system configuration file: man sudoers.
请注意，您sudo不需要退出它，而是 sudo 会记住您上次进行身份验证的时间，并且如果足够新，则不需要重新进行身份验证。此命令将时间戳重置为纪元。您可以在系统配置文件中更改超时值：man sudoers.
