osascript using bash variable with a space

Question

I am using osascript in Bash to display a message in Notification Center (Mac OS X) via Apple Script. I am trying to pass a text variable from Bash to the scrip

Answer 1

This version is completely safe against injection attacks, unlike variants trying to use string concatenation.

osascript \
  -e "on run(argv)" \
  -e "return display notification item 1 of argv" \
  -e "end" \
  -- "$var2"

...or, if one preferred to pass code in on stdin rather than argv:

osascript -- - "$var2" <<'EOF'
  on run(argv)
    return display notification item 1 of argv
  end
EOF
