bash script asks user to enter password in Finder window to do some root actions (it was useful for me in xCode project prebuilt script)

sudo ask pass source redefinition, MacOS

TITLE="Please, enter root password"
DIALOG="display dialog \"$@\" default answer \"\" with title \"$TITLE\""
DIALOG="$DIALOG with icon caution with hidden answer"

result=`osascript -e 'tell application "Finder"' -e "activate"  -e "$DIALOG" -e 'end tell'`

export SUDO_ASKPASS="$result" | sed -e 's/^text returned://' -e 's/, button returned:.*$//'

gem list --local compass| grep -q compass
COMPASS_INSTALLED=$?
if [ $COMPASS_INSTALLED -eq 1 ]; then
  sudo gem install compass --pre
