Back in the early days of Linux<\/a>, things were exponentially more complicated. The distributions were far less mature and required a particular system account to get things done. That account was root — and with it, you had unlimited power over your operating system. <\/p>\n

To demonstrate the power of the root account, one trick you could always play on unsuspecting users was to tell them to change to the root user with the su command <\/em>and then have them issue the following command:<\/p>\n

The rm command is used to delete files and folders. In conjunction with r (recursive) and f (force), you would delete everything from the root folder (\/), thus rendering your system unusable. <\/p>\n

Back then, any command that required administrative privileges was run via the root user. To do that, you either had to change to the root user (with the su command) or log in as the root user. Both of these options were eventually considered a security issue<\/a>. A user could do anything if you logged in as the root user and walked away from your system. <\/p>\n

Access to the root user meant that if a hacker gained access to your system, they could wreak havoc on the machine.<\/p>\n

Eventually, it was decided something had to give<\/a>. Out of that need, sudo was born<\/a>. Sudo stands for “superuser do” and effectively allows a regular user (one that belongs to the admin group) access to administrator-like powers. This approach solved two problems:<\/p>\n
