May 04, 2019 · sudo will check the ownership of its timestamp directory (/var/run/sudo by default) and ignore the directory's contents if it is not owned by root and only writable by root.

It originally stood for "superuser do" as the older versions of sudo were designed to run commands only as the superuser. However, the later sudo su lauches su directly with super user privileges, while sudo bash lauches the shell first and then executes the command with bash -c. The main difference would be that your .bashrc script will be run before executing the su - root command. The outcome depends on that. Use cases: Lauch bash with elevated privilges, using your own password

From the man pages for bash and sudo it seems that the difference may be that sudo bash -l runs ~/.bash_profile, ~/.bash_login, and ~/.profile, and ~/.bash_logout of the root user, but from testing myself it looks like it runs the normal user's .bashrc and not the root one.

linux - What happens when I sudo bash -c? - Stack Overflow

Sep 07, 2019 · sudo echo "test" > /root/file.txt bash: /root/file.txt: Permission denied. This happens because the redirection “>” of the output is performed under the user you are logged in, not the user specified by sudo. The redirection happens before the sudo command is invoked. One solution is to invoke a new shell as root by using sudo sh -c: ssh sudo su - privledged_user cat logs > file.txt Running this with sh -x reveals bash is getting stuck on the 'ssh' line.
