linux - Run scipt like sudo with Gksudo -

-

I'm new in linux I'm trying to mount and umount. ISO with nano script I put the script /home/user/.gnome2/nemo-scripts/ . My problem is, with gksudo I run su command like only 1. How do I run this script? 

  #! / Bin / bash gksudo -k / bin / echo "got r00t?" BNAME = $ (basename "$ NEMO_SCRIPT_SELECTED_FILE_PATHS") sudo mkdir "/ Media / $ BNAME" --info --title "ISO Mounter" zenity if sudo is ISO9660 $ Income Tax - o loop mount --text "$ BNAME e $ NEMO_SCRIPT_SELECTED_FILE_PATHS" NEMO_SCRIPT_SELECTED_FILE_PATHS "/ Media / $ BNAME" if zenity --question --title "ISO Mounter" --text "$ BNAME successfully mounted. Open Volume?" Then the Nemo / Media / $ BNAME --no- the rest of the desktop fi exit 0 sudo rmdir "/ media / $ bname" zenity --error --title "ISO mounter" --text "$ can not be mounted BNAME! "  
  
 
 
 There are a couple of ways to do this in your script above, you  root You can execute the full script with permission  if you call the script only with the  su -c script  or  sudo script . Before doing this, edit your script and remove the call at  gksudo  and  sudo . Then adding a test to insure the script at the top of your script is run with an effective root UID. Ex: 
 
  #! / Bin / bash if test "$ UID" -ec 0; So run the script as "printf" root \ n "other printf" error, this script can only be run by root \ n "exit 1; Fi  
 
 Then make sure that you run your script as  sudo scriptname  or  su -c scriptname . Additionally,  Make sure that you have an executed bit set of your script file permissions  You will simply give this  chmod 0775 SCRIPTNAME script  which you can do with  owner < / Code> and  groups  read-write-executed permissions and read-execute  world  permissions. If you do not want it to be world executable, just click  chmod 0774 . 
 
  If you do not set permission for execution on your script , you can not get a  permission denied  or  order  Get the error You can execute the script by specifying the shell in your  sudo  or  su  call, e.g.  sudo bash SCRIPTNAME script  or  su -c "Bash SCRIPTNAME script" , but this script is preferred to make it executable.

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
