How to enable sudo on Debian 7.0 with the visudo command.

Posted: May 9, 2013. At: 9:56 PM


The visudo command is used on Linux systems to edit the /etc/sudoers file; this ensures that there are no errors before the changes are written to the actual file. As you can see below; I have added my user homer to the sudoers file. This allows me to run commands with sudo; but will still ask for my users password before running the command.

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults	env_reset
Defaults	mail_badpass
Defaults	secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
 
# Host alias specification
 
# User alias specification
 
# Cmnd alias specification
 
# User privilege specification
root	ALL=(ALL:ALL) ALL
 
# Allow members of group sudo to execute any command
%sudo	ALL=(ALL:ALL) ALL
homer ALL=(ALL:ALL) ALL
 
# See sudoers(5) for more information on "#include" directives:
 
#includedir /etc/sudoers.d

This is how you enable the sudo command for the normal user on Debian GNU/Linux 7.0. This is not very difficult at all; just make sure you NEVER edit the /etc/sudoers file with any other editor. Use the visudo command.
