executing shutdown.sh script as sudo-user not working

Question

I want to shut down a tomcat server. To this end I went to the bin directory of the tomcat installation and wanted to execute the shutdown.sh script, as described in the approved answer to this question:

Several ports (8005, 8080, 8009) required by Tomcat Server at localhost are already in use

I first simply tried

./shutdown.sh

I received the following error message:

-bash: ./shutdown.sh: Permission denied

So I tried the following command:

 sudo ./shutdown.sh

This gave me the following error message:

sudo: ./shutdown.sh: command not found

So how can I run the shutdown.sh script as sudo-user? What is the correct syntax?

Answer 1

You should be able to run

sudo -i /path/to/executable.sh

Since the -i flag:

[Run's] login shell as the target user

Answer 2

Try granting privileges by

chmod 755 ./shutdown.sh

Answer 3

run bellows,

sudo chmod 777 shutdown.sh
sudo ./shutdown.sh
