sudo (/ s uː d uː / [4]) is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. [5] It originally stood for "superuser do", [ 6 ] as that was all it did, and this remains its most common usage; [ 7 ] however, the official Sudo project ...
It might require Super User Privileges to run the command. If it does then proceed with the commands below $ sudo alien ${filename}.rpm # Rpm to Deb $ sudo alien-k ${filename}.tar.gz # Tar.gz to Deb $ sudo alien-d ${filename}.tar.bz2 # Tar.bz2 to Deb $ sudo alien--to-deb ~/ ${filename}.tgz # Tgz to Deb $ sudo alien-r ${filename}.deb
Sudo command on Ubuntu to temporarily assume root privileges. Most Unix and Unix-like systems have an account or group which enables a user to exact complete control over the system, often known as a root account. If access to this account is gained by an unwanted user, this results in a complete breach of the system.

A privilege is applied for by either an executed program issuing a request for advanced privileges, or by running some program to apply for the additional privileges. An example of a user applying for additional privileges is provided by the sudo command to run a command as superuser user, or by the Kerberos authentication system.
For example, the ping command may need access to networking privileges that a normal user cannot access; therefore it may be given the setuid flag to ensure that a user who needs to ping another system can do so, even if their account does not have the required privilege for sending packets.
Privilege escalation means users receive privileges they are not entitled to. These privileges can be used to delete files, view private information , or install unwanted programs such as viruses. It usually occurs when a system has a bug that allows security to be bypassed or, alternatively, has flawed design assumptions about how it will be used.
