Removing an Excel Workbook VBA Password

A VBA project password can be removed with a hex editor. Close the workbook and open the workbook file in the hex editor. Find the string "DPB" and change it to "DPx". Save the file. Open the workbook and click OK until the workbook is open (one or more dialogs are displayed describing various problems with the VBA project). Press ALT+F11, choose the menu command Tools->VBAProject Properties, navigate to the Protection tab, and change the password but do not remove it (note the new password). Save, close, and re-open the workbook. Press ALT+F11 and enter the new password. Choose Tools->VBAProject Properties, navigate to the Protection tab, and remove the password. Save the workbook.

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
