What should I do if the wget command cannot be used in CentOS

The wget command cannot be used in CentOS because it is not installed. You only need to install it.

1. Check whether it is installed:

(recommended learning: Linux video tutorial)

rpm -qa|grep "wget"

If it is installed The installation will display wget related information. If no information is displayed, it means it is not installed, and the wget command cannot be used.

2. Install wget

yum -y install wget

When you see Complete!, it means the installation is completed successfully!

3. Check again to see if it is installed (The following version information appears to indicate successful installation)

4. Enter wget - h for testing
