In my opinion, with "sudo mvn -v", everything must be same for root (#). Use the following syntax with echo, sudo and tee command: echo ‘string-of-text’ sudo tee -a pathtofile For example: echo 'deb lsbrelease -cs nginx' \ sudo tee /etc/apt//nginx.list. OS name: "linux", version: "5.19.0-41-generic", arch: "amd64", family: "unix" What do sudo and su mean on Linux environments sudo Substitute User DO su Substitute User A brief history Which is the difference between. Secondly: sudo -i and su - do the same thing ( su - is equivalent to su -login ), using different authorization mechanism: su verifies the password for the root account, while sudo verifies the password for your current user account and also verifies that your current user account is allowed to run administrative operations according to the. Java version: 11.0.18, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64ĭefault locale: en_US, platform encoding: UTF-8 71 In addition to what you said, su requires the root password and sudo requires your user password Therefore sudo su - will put you into a root environment but it will ask you for your user password instead of the root password (once sudo has given you root privileges, su - can be executed with no password). When I try to execute mvn, there is three situtations:Īpache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d) I edited /etc/bash.bashrc as in this link. I download intellij idea and I want to use its mvn lib for everyone. If you want 100 certainty in your logging, you need to restrict sudo heavily and disallow sudo su entirely. I have one user (ahmet) and it is member of sudo. 1 If someone malicious (or even just untrustworthy) has access to sudo su -, they also have the ability to remove all the log entries you could make of their actions. Despite all this, SU still has its own use, mostly when switching to other user accounts to gain access to their files.My Ubuntu version is Ubuntu 22.04.2 LTS. This is probably what led to the misconception of SUDO as super user do. SUDO is also used by many ordinary Linux users to do tasks that require super user access. With SUDO, there is no need to share passwords as it can elevate the privileges of individual users and allow them to have access to the things that they need but not to those they don’t.īecause of these advantages, SUDO is preferred by many. It is a major weakness as there is no limitation in place for each user. With SU, it is common practice to create a root account and share it to those who need it via SU. The log makes it easier to track where mistakes have been made and to correct them. Another advantage of SUDO is the log that is kept for every command. This provides a lot of flexibility, especially in systems with a lot of users. The constraints are placed in a conf file that can be edited. SUDO has become a favorite among admins due to the ability to define constraints on whether a user can use SUDO and what commands he can use with it. This is very useful when you only want to do a single command that requires root access succeeding commands would also be given root access. Both su and sudo elevate privileges assigned to the current user. With SUDO, another command is often attached and executed automatically after the authentication succeeds. The most noticeable difference between the two would be the usage as SU is commonly used on its own or with the substitute username as a parameter. SU stands for substitute user and SUDO means substitute DO although most people incorrectly think that it stands for super user as it is the account that is often used. In the Linux and UNIX environments, you need to use either SU or SUDO in order to gain momentary access to another account, usually the root, while logged on as another.
