I'd like to run an OSX application with admin privileges, so the user would be asked first for his admin log/pass.
Is there a bash command or an applescript command that would allow me to do that ?
Sort of a sudo command but with a graphic dialog shown to the user, similar to what the Finder shows when asking permission to write files in restricted folders.
(if by OSX application are you talking about the applescript one?)
In applescript, you can display a dialog that finder displays for the users login and password but this will not tell you the password, it will basically run a shell script as sudo:
do shell script "myadminshellcommand arguments" with administrator privileges
By adding "with administrator privileges" you are telling AppleScript to run a shell script in sudo with the users password
(Don't add sudo to the command)
