Adding a new user in sudoers list with root user privilege (ubuntu)

For adding a new user in the 'sudoers' list follow the procedures given below:
(in order to do this you should have root user privilege)

--> Take terminal window (from Applications->Accessories->Terminal or press Ctrl+Alt+T)

--> Type the command: sudo visudo

the terminal will display something like this:

------------------------------------------------------------------------------------------------------------------------------

GNU nano 2.2.2            File: /etc/sudoers.tmp

 

# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
#
Defaults        env_reset

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification

root    ALL=(ALL) ALL

# Allow members of group sudo to execute any command after they have

# provided their password

# (Note that later entries override this, so you might need to move

# it further down)

%sudo ALL=(ALL) ALL

#

#includedir /etc/sudoers.d

# Members of the admin group may gain root privileges

%admin ALL=(ALL) ALL

-----------------------------------------------------------------------------------------------------------------------------

--> Now, after the 'root ALL=(ALL) ALL' statement, add your username in the following syntax:

domainname\\username = ALL=(ALL) ALL

eg: CODETECH\\tiger ALL=(ALL) ALL

Note: at the time of login you have to give CODETECH\\username as username

How to add text completion functionality to Gedit text editor (Ubuntu)

Today many open source text editors are available, for Ubuntu and Debian operating systems (OS). Both OS have 'gedit' as their default text editor. In its default settings gedit will not provide advanced auto text completion, but you can modify the settings to avail this functionality.

Many times my fellow developers asked me why I am using gedit for coding, while other more advanced editors are available. I didn't had a reason to support my favor to gedit, but personal preference. I thought about making gedit a more useful editor like geany, sublime etc.(both are open source editors) and i searched in Google for improving the coding standards and editor efficiency, finally I found the Gedit plugin.

You can download this plugin from the below links.

download gedit plugin from here (for ubuntu 11.04 or below)
