A personal memo for the first week of joining the company.
Entering vm of Virtualbox and working on environment construction .. When I tried to open the file according to the procedure manual, I got angry as follows.
When you type the
vi / etc / filename command
** Unable to open file for writing **
Execute with sudo privilege as follows to solve.
sudo vi /etc/file name
sudo command **
Execute the command with superuser (root user) privileges.
You can set it to run without a password, or you can run the command with your own password to run the sudo command.
The "root" user has "administrator privileges" on Linux and Unix Like Systems.
It has the same meaning as administrator in Windows.
