How to Install wget, telnet, man Utility on CentOS 6.4

CentOS is a popular open-source operating system that is widely used for web servers, network services, and databases. One of the advantages of CentOS is its package manager called YUM, which allows easy installation and management of software packages. However, some packages are not installed by default, such as wget, telnet, and man utility.

[root@centos64 ~]# wget
-bash: wget: command not found
[root@centos64 ~]# man
-bash: man: command not found
[root@centos64 ~]# telnet
-bash: telnet: command not found

These utilities are essential for managing and troubleshooting network-related issues. In this guide, we will explain how to install these utilities on CentOS 6.4 using the YUM package manager.

Step 1: Check if the utilities are already installed:

Before we proceed with the installation, let’s check if the utilities are already installed on your system. To check if the wget utility is installed, run the following command:

which wget

If the output shows the location of the wget binary, then it is already installed on your system. Similarly, you can check the telnet and man utility using the following commands:

which telnet
which man

If the utilities are not installed, move to the next step.

Step 2: Install wget:

To install the wget utility, run the following command:

sudo yum install wget

The YUM package manager will download and install the wget utility along with its dependencies.

Step 3: Install telnet:

To install the telnet utility, run the following command:

sudo yum install telnet

The YUM package manager will download and install the telnet utility along with its dependencies.

Step 4: Install man utility:

The man utility provides help and documentation for other commands installed on your system. To install the man utility, run the following command:

sudo yum install man

The YUM package manager will download and install the man utility along with its dependencies.
