The centos system cannot find the command

Problem:

Any command entered shows

bash: xxxx: command not found...

Solution:

One: Directly in linux Enter the following on the command line interface and press Enter (to import environment variables and the storage addresses of common shell commands):

(Recommended tutorial: centos usage tutorial)

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

Second: If all commands in the system cannot be used, you can also use the absolute command vi to open profile

/bin/vi  /etc/profile

Add the environment variable address to the system configuration file

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