First execute the following command:

[root@zcwyou ~] # echo $PATH

The output is as follows:

/ usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

If there are two executable files with the same name in two different directories, shell will run the directory included by the environment variable in PATH, using the C2C or C3C command:-G0G, with an output similar to the following: / usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
