Include sudo password in linux executable file

Question

I have this code in a linux executable file to start atom from there:

#! /bin/bash

sudo atom

I wanted to include sudo password after that lines of code, so the program will run automatically.

That said, *don't do it this way!* (bad idea). Anyone who can read the file can read the sudo password. Instead run `visudo` and set the appropriate permissions for this user to run `sudo` without a password (you will probably have to add the user to the `wheel` (or lately the `sudo`) group as well. — David C.

I wouldn't suggest hardcoding a password into your script as it carries a security risk.

Strictly speaking you can by doing:

echo "yourpassword" | sudo -S <command>

The -S flag will read the password from stdin.

There is another better way for you to allow password-less sudo commands by modifying your sudoers file.

Why you not use sudoers? Try running atom without password.

Edit /etc/sudoers via visudo:

visudo -f /etc/sudoers

Put new line and save:

youuser ALL=(ALL:ALL) NOPASSWD: atom

do not forget to replace youuser

You dont need this. You need to use visudo:

sudo visudo

Then add line like this:

username ALL=(root) NOPASSWD: /path/to/script.sh

And then run your script using sudo script.sh without password
