When do I need to set the root path for Sudo?
This is the path used for every command run with sudo, it has two importances: Used when a system administrator does not trust sudo users to have a secure PATH environment variable To separate “root path” and “user path”, only users defined by exempt_group are not affected by this setting. To set it, add the line:
Where do I set secure path in Su?
If the secure_path option is set, its value will be used for the PATH environment variable. This flag is on by default. As a workaround, you can use sudo su that will provide a shell with root privileges but containing the right PATH. You should set it in /etc/environment.
Why does Sudo change the path when using Su?
The PATH will be reset when using su or sudo by the definition of ENV_SUPATH, and ENV_PATH defined in /etc/login.defs $PATH is an environment variable and it means that value of $PATH can differ for another users. When you are doing login into your system then your profile setting decide the value of the $PATH.
Where do I find the PATH variable in Sudo?
The default contents of the env_keep and env_check lists are displayed when sudo is run by root with the -V option. If sudo was compiled with the SECURE_PATH option, its value will be used for the PATH environment variable.
How do I get root privileges in Sudo?

Sudoers file can be access from /etc/sudoers . Example sudoers file can be found below ## ## The COMMANDS section may have other options added to it.
Why does Sudo reset the environment by default?
The reason for that is sudo has a policy of resetting the Environment and setting a secure path. It is enabled by default: Thus whatever is set in the /etc/environment for the path is overridden by sudo. env_reset If set, sudo will reset the environment to only contain the LOGNAME, MAIL, SHELL, USER, USERNAME and the SUDO_* variables.
What kind of environment do I get with sudo?
When I run sudo command, it doesn’t seem to see my or root’s environment. For example, my path for both includes /usr/local/bin, but if I try to run one of the program’s without the full path, it fails. I thought sudo ran as root, and hence got root`s environment.
