linux - Ubuntu prompts permission denied when executing sh

Question

My Baidu website said this works$ sudo chmod -R 777 myResources But it didn’t work after trying it. Is there any way to solve it?

Answer 1

I want to authorize the script and then execute it

chmod 777 ./redis.sh  

Also when I saw you executing chmod时, 报错command not found! 这可能跟你执行sudo有关, 你可能没有配置好, 导致sudo时没有携带环境变量, 找不到命令, 你可以用绝对路径去执行, 或者不用sudo, 直接 chmod .....(省略)

Answer 2

sudo sh mysql.sh

Answer 3

One suggestion, if you use sh script this way, you may get into trouble. The default shell of ubuntu is dash, so an error will be reported~

Answer 4

I also tried it like this. Why is there no response? chmod 777 ./redis.sh
