The reason for this problem is that the environment variables of the system are not configured correctly. There are many reasons, such as system upgrade, improper operation and so on, which lead to the overwriting and modification of environment variables. There are two ways to solve this problem.

Method 1: enter the following directly in the linux command line interface, and then enter (import environment variables and the storage address of common shell commands):

Export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

Method 2: if all the commands on the system are not available, you can also use the absolute command vi to open profile

/ bin/vi / etc/profile

Add the environment variable address to the configuration file of the system

Export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

These are the details that linux system commands cannot be used. Please pay attention to other related articles for more information.
