Can we use Sudo in shell script?

sudo is a powerful command line tool that enables a “permitted user” to run a command as another user (the superuser by default), as defined by a security policy. Therefore, to run a shell script or program as root, you need to use sudo command.

How do you kill a running shell script in Unix?

You can use ps + grep or pgrep to get the process name/pid; later use killall / pkill to kill process name or use kill to kill pid.

Is it possible to execute a shell script with sudo?

(It’s actually even more impossible than that, because the sudo command itself is executed as a subprocess of the current shell — meaning that in a sense it’s already too late for it to do anything in the “current shell”, because that’s not where it executes.) seems to work for me.

Is there a way to run Sudo without using sudo?

I do not have access to sudo anything else. Problem is, this script stops randomly, and someone needs to keep restarting it, which is annoying. I created the below script (I’ll call this the babysitter script) to automate this. In short, it’s running 2 parallel instances of the script simultaneously, and restarts them up to 5 times if they stop.

Why does Sudo Su run the rest of the script as?

The Script itself as the parent of all commands in the script, is another independent process and the su command does not and can not change it to root: the su command creates a new process with root privileges. After that su command completes, the parent process, still running as the same user, will execute the rest of the script.

Can a shell script be run in a root process?

The subprocess could be just a regular program (e.g. sudo cp runs the cp program in a root process) or it could be a root subshell, but it cannot be the current shell.
