How to check if command needs sudo?

[GerishSonya]

I have a question regarding sudo permissions. While it's possible to check if a user has sudo access on Oracle Solaris using "sudo -l -U (user)," is there a way to determine whether a specific command requires sudo privileges or not? For instance, if I need to execute the "hostname" command, how can I verify if it needs sudo permissions? I'm not well-versed in this area and prefer not to execute commands directly on the server. Thank you.

Yes, you can determine whether a specific command requires sudo privileges or not by checking the permissions of the command's executable file. The executable file's permissions will show whether the command is executable by everyone, only by the user who owns the file, or by a specific group.

To check the permissions of the executable file for the "hostname" command, you can use the "ls" command followed by the path to the command's executable file. For example, if the "hostname" command is located in the "/usr/bin/" directory, you can run the following command:


ls -l /usr/bin/hostname
This will show you the file's permissions, which will be displayed as a series of letters and symbols. The permissions are divided into three sections: the owner's permissions, the group's permissions, and everyone else's permissions.

If the owner's permissions include the "x" symbol, it means that the command is executable by the owner. If the group's permissions include the "x" symbol, it means that the command is executable by members of the group. If everyone else's permissions include the "x" symbol, it means that the command is executable by everyone.

If the permissions do not include the "x" symbol for any of the sections, it means that the command cannot be executed by anyone.

In the case of the "hostname" command, it is typically executable by everyone, so you should be able to run it without sudo privileges. However, it's always a good idea to double-check the permissions before running any command to ensure that you have the necessary permissions to execute it.
