root 권한으로 파일실행

sudo

sudo가 설치가 안되어 있으면 visudo 등을 사용....

sudo 설치된 상태에서 /etc/sudoers에서 설정하면 특정 그룹에 있는 user가 sudo 명령어 사용할때 passwd 안묻도록 할 수 있음

if you really want to have a script run as a user and be able to execute commands as root, there are 2 options that I know of.

1. 
   
   
   
   
   

   Use sudo with stored password:

   #!/bin/sh
   whoami
   sudo -S -p "" whoami <<EOF
   mysuperpassword
   EOF
   

   
   
   
   
   
   

   Which will output (when run as 'user'):

   user
   root
   

   
   
   
   
   
   
2. 
   
   
   
   
   

   Use sudo with no password.
   Add a list of the commands that you wish to run into the /etc/sudoers file by running visudo as root. For example, to allow user to run the commands apache2ctl and whoami, add the following:

   User_Alias SPECIAL = user
   Cmnd_Alias SPECIAL_COMMANDS = /usr/sbin/apache2ctl, /usr/bin/whoami
   SPECIAL ALL = NOPASSWD: SPECIAL_COMMANDS
   

   
   
   
   
   
   

   Or if you really trust user, if it's you for example, you can allow the user to execute any command without a password:

   user ALL=(ALL) NOPASSWD: ALL
   

   
   
   
   
   
   

   Then when the following script is run by user:

   #!/bin/sh
   whoami
   sudo whoami
   

   
   
   
   
   
   

   It will output:

   user
   root
