[问题]gksu和sudo命令有什么不同？［已解决］

gksu和sudo命令有什么不同？

[skyx]

以下全为听说，没有学习过，也没查过相关资讯。

gksu 用于启用gui程式， sudo 用于CLI。

听说 sudo gui程式，会出问题,为什么会出问题，会出什么问题，不知道，

倒底有什么区别，没感觉到。

比如 sudo nautilus 和gksu nautilus

除了password输入方式不同外，没什么区别

[飞雪笑]

不晓得哈，你 man sudo 再 man gksu不久可以了吗
英文不好的话可以sudo --help 再 gksu --help 比较一下好像也可以啊
我刚刚把ubuntu给格了，现在就一个xp，呵呵，没有试验的地方

sudo allows a permitted user to execute a command as the superuser or
another user, as specified in the sudoers file. The real and effective
uid and gid are set to match those of the target user as specified in
the passwd file and the group vector is initialized based on the group
file (unless the -P option was specified). If the invoking user is
root or if the target user is the same as the invoking user, no pass‐
word is required. Otherwise, sudo requires that users authenticate
themselves with a password by default (NOTE: in the default configura‐
tion this is the user’s password, not the root password). Once a user
has been authenticated, a timestamp is updated and the user may then
use sudo without a password for a short period of time (15 minutes
unless overridden in sudoers).

When invoked as sudoedit, the -e option (described below), is implied.

sudo determines who is an authorized user by consulting the file
/etc/sudoers. By giving sudo the -v flag a user can update the time
stamp without running a command. The password prompt itself will also
time out if the user’s password is not entered within 0 minutes (unless
overridden via sudoers).

If a user who is not listed in the sudoers file tries to run a command
via sudo, mail is sent to the proper authorities, as defined at config‐
ure time or in the sudoers file (defaults to root). Note that the mail
will not be sent if an unauthorized user tries to run sudo with the -l
or -v flags. This allows users to determine for themselves whether or
not they are allowed to use sudo.

If sudo is run by root and the SUDO_USER environment variable is set,
sudo will use this value to determine who the actual user is. This can
be used by a user to log commands through sudo even when a root shell
has been invoked. It also allows the -e flag to remain useful even
when being run via a sudo-run script or program. Note however, that
the sudoers lookup is still done for root, not the user specified by
SUDO_USER.
sudo can log both successful and unsuccessful attempts (as well as
errors) to syslog(3), a log file, or both. By default sudo will log
via syslog(3) but this is changeable at configure time or via the sudo‐
ers file.

sudo nautilus

gksu nautilus

二者在终端中的提示信息的确不同，后者多一点内容。

我怎么知道是 gui 程式还是用于 CLI ？一般程序应该是什么程式？

sudo gui 程式，会出问题，那么是不是永远用 gksu 启动 gui 和 CLI 程式就不会出问题了？

GUI = Graphical User Interface 就是有图形界面的
CLI = Command Line Interface 就是命令行的东东

原来如此，谢谢了！

我用sudo运行GUI和CLI都没问题，用gksu运行GUI也没问题，用gksu运行CLI也没问题（用apt和nano作的实验），但一个脚本，里面使用了CLI，sudo没问题，gksu却出现下列错误：
