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 script. For a variable without spaces, this works just fine, but not for one with spaces:
Defining
var1="Hello"
var2="Hello World"
and using
osascript -e 'display notification "'$var1'"'
works, but using
osascript -e 'display notification "'$var2'"'
yields
syntax error: Expected string but found end of script.
What do I need to change (I am new to this)? Thanks!
You could try to use instead :
osascript -e "display notification \"$var2\""
Or :
osascript -e 'display notification "'"$var2"'"'
This fixes the problem of manipulation of variables that contains spaces in bash. However, this solution doesn't protect against injections of osascript code. So it would be better to choose one of Charles Duffy's solutions or to use bash
parameter expansion :
# if you prefer escape the doubles quotes
osascript -e "display notification \"${var2//\"/\\\"}\""
# or
osascript -e 'display notification "'"${var2//\"/\\\"}"'"'
# if you prefer to remove the doubles quotes
osascript -e "display notification \"${var2//\"/}\""
# or
osascript -e 'display notification "'"${var2//\"/}"'"'
Thank to mklement0 for this very useful suggestion !
