没有密码无法运行 sudo 脚本？

我正在使用 arch linux - i3。我有一个脚本要运行rmmod hid-multitouch && sudo modprobe hid-multitouch。我在 i3 中编辑了热键并设置了一个例外来运行没有密码的脚本，使用sudo visudo取消注释并添加了行

%wheel ALL=(ALL) NOPASSWD: /home/hieuc/i3script/rmod_hid.sh
hieuc ALL=(ALL) NOPASSWD: /home/hieuc/i3script/rmod_hid.sh
但它似乎不起作用，但几天前它仍然对我有用。这是一个输出/etc/sudoers

## sudoers file.
##
## This file MUST be edited with the 'visudo' command as root.
## Failure to use 'visudo' may result in syntax or file permission errors
## that prevent sudo from running.
##
## See the sudoers man page for the details on how to write a sudoers file.

##
## Host alias specification
##
## Groups of machines. These may include host names (optionally with wildcards),
## IP addresses, network numbers or netgroups.
# Host_Alias    WEBSERVERS = www1, www2, www3

##
## User alias specification
##
## Groups of users.  These may consist of user names, uids, Unix groups,
## or netgroups.
# User_Alias    ADMINS = millert, dowdy, mikef

##
## Cmnd alias specification
##
## Groups of commands.  Often used to group related commands together.
# Cmnd_Alias    PROCESSES = /usr/bin/nice, /bin/kill, /usr/bin/renice, \

## Defaults specification
##
## You may wish to keep some of the following environment variables
## when running commands via sudo.
##
## Locale settings
# Defaults env_keep += "LANG LANGUAGE LINGUAS LC_* _XKB_CHARSET"
##
## Run X applications through sudo; HOME is used to find the
## .Xauthority file.  Note that other programs use HOME to find   
## configuration files and this may lead to privilege escalation!
# Defaults env_keep += "HOME"
##
## X11 resource path settings
# Defaults env_keep += "XAPPLRESDIR XFILESEARCHPATH XUSERFILESEARCHPATH"
##
## Desktop path settings
# Defaults env_keep += "QTDIR KDEDIR"
##
## Allow sudo-run commands to inherit the callers' ConsoleKit session
# Defaults env_keep += "XDG_SESSION_COOKIE"
##
## Uncomment to enable special input methods.  Care should be taken as
## this may allow users to subvert the command being run via sudo.
# Defaults env_keep += "XMODIFIERS GTK_IM_MODULE QT_IM_MODULE QT_IM_SWITCHER"
##
## Uncomment to use a hard-coded PATH instead of the user's to find commands
# Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
##
## Uncomment to send mail if the user does not enter the correct password.
# Defaults mail_badpass
##
## Uncomment to enable logging of a command's output, except for
## sudoreplay and reboot.  Use sudoreplay to play back logged sessions.
# Defaults log_output
# Defaults!/usr/bin/sudoreplay !log_output
# Defaults!/usr/local/bin/sudoreplay !log_output
# Defaults!REBOOT !log_output

##
## User privilege specification

root ALL=(ALL) ALL

## Uncomment to allow members of group wheel to execute any command
%wheel ALL=(ALL) ALL

## Same thing without a password
%wheel ALL=(ALL) NOPASSWD: /home/hieuc/i3script/rmod_hid.sh
## User
hieuc ALL=(ALL) NOPASSWD: /home/hieuc/i3script/rmod_hid.sh

## Uncomment to allow members of group sudo to execute any command
# %sudo ALL=(ALL) ALL

## Uncomment to allow any user to run sudo if they know the password
## of the user they are running the command as (root by default).
# Defaults targetpw  # Ask for the password of the target user

我的脚本：

#! /bin/bash

sudo rmmod hid-multitouch && sudo modprobe hid-multitouch

这是我在 i3 中的热键bindsym $mod+Shift+o exec $HOME/i3script/rmod_hid.sh

答案1

假设/home/hieuc/i3script/rmod_hid.sh是您的脚本，您应该sudo /home/hieuc/i3script/rmod_hid.sh无需密码即可运行。 sudo 权限适用于指定的命令，而不适用于从 sudo 配置中指定的脚本调用的命令。

另一方面，您的脚本不需要 sudo，因为它已经以 root 身份运行。

#! /bin/bash
rmmod hid-multitouch && modprobe hid-multitouch

如果您希望能够在不使用 sudo 的情况下调用脚本，您可以检查用户 ID：

#! /bin/bash
test "$(id -u)" != 0 && exec sudo /home/hieuc/i3script/rmod_hid.sh "$@"
rmmod hid-multitouch && modprobe hid-multitouch

sudo如果没有调用它，则它会调用自己sudo。然后，调用的脚本sudo将以 root 身份执行最后一行中的命令。

答案2

hieuc ALL=(ALL) NOPASSWD: /home/hieuc/i3script/rmod_hid.sh

sudoers 文件中的这一行允许用户希厄克执行/home/hieuc/i3script/rmod_hid.sh时sudo不提示输入密码。例如：

hieuc$: sudo ~/i3script/rmod_hid.sh

由于脚本已经以 root 身份运行，因此您不需要sudo在脚本内部使用。

请注意，拥有可以使用 sudo 运行的用户可写文件意味着用户可以以 root 身份运行任何命令（通过修改该脚本）。

答案3

您提到的脚本sudoers是您将运行的脚本sudo。

所以如果你想做的话sudo /home/me/my-script就/home/me/my-script必须在中提到sudoers

根据您的情况，您可以添加modprobe hid-multitouch到sudoers

您还可以编写 script1 来包含 sudo script2

并将脚本 2 放入sudoers.

例如

script1由热键代码调用。它没有提到suderes 它包含：

#!/bin/bash
script_called_as="$0"
script_full_name="$(readlink -e "$script_called_as")"
script_dir="$(dirname "$script_full_name")"

sudo "$script_dir/«script2»"

替换«script2»为您的脚本的名称。然后讲述sudeers你的 script2 （不是 script1）
