For security reasons, the use sudo to execute the command will be executed in a minimal environment, environment variables are reset to the default state. So user-defined settings content of the PATH variable does not include
add the following .bashrc in the user's home directory sudo can be solved in
$ vim ~/.bashrc
alias sudo="sudo env PATH=$PATH"There is such a shell script, which reads as follows, did not give its permission x
vim test.sh
#!/bin/bash
echo "${PATH}"# 执行该脚本，可以看到echo输出的结果
[test_ops@iZ2zej3o3e9be3aoukimfzZ ~]$ bash test.sh

# 但是加上sudo，上述结果就不显示了，而是一个系统默认的${PATH}变量结果
