Information on using sudo or gksudo on scripts without password

You need to do the following, on the terminal type sudo visudo and add a line like this at the end of the file specifying the commands you want to run without typing the sudo password:

<yourusername> hostname=NOPASSWD: <command1>, <command2>

Now you can run the specified commands without password as long as you type that command with sudo.

ie: lets you want to run shutdown -r now without having to type sudo password everytime and your username is 'joedoe'

1. type sudo visudo on a terminal

   
   



2. Add joedoe hostname=NOPASSWD: shutdown -r now as a new line at the end of the file

   
   



3. on your script you can then use sudo shutdown -r now without having to type the sudo password.

   
   

To create a scrip use your favorite editor to create a <nameofyourscript>.sh with the contents:

#! /bin/bash



sudo <commandsyouwanttorun1>

<commandsyouwanttorun2>

sudo<commandsyouwanttorun3>

Use sudo to call commands that need it, it wont ask for password as long as you added that on the NOPASSWD: <commmand1>, <command2>, etc line in visudo.

After that you need to make it executable with: sudo chmod 755 <nameofyourscript>.sh.

Now you can run your script using sh <nameofyourscript>.sh on a terminal, by double clicking on it and selecting run on the dialog box or put them in your ~/.gnome2/nautilus-scripts/ which then will be available on your scripts menu when you right click on nautilus:

Create a right-click "Open as admin" without password

To create a scrip that opens files using administrator permissions by right clicking on them and making it so that no passwords will be asked create a script with the following:

#! /bin/bash

for file in $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS; do

gksudo "gnome-open $file" &

done

Save it on your ~/.gnome2/nautilus-scripts/, make it executable with sudo chmod 755 ~/.gnome2/nautilus-scripts/<nameofyourscript>.sh, using sudo visudo add the line <yourusername> ALL=NOPASSWD: /usr/bin/gnome-open and save the file.

You should be able to right-click a file, move to your scripts folder and selecting the script you just created to open that file using root permistions. gnome-open will handle the file type as good as possible.
