Using growlnotify
how can I display multiple lines of text from the command line?
Slash-n - \n
- like this doesn't seem to work:
growlnotify -t title -m "messageline1\nmessage2"
I just get a message messageline1\nmessage2
The intended escaped newline is not interpreted as such by growl - it's just treated as a literal slash, followed by an 'en'.
You can get the shell to insert a newline in the string this way:
growlnotify -t title -m "messageline1"$'\n'"message2"
See (e.g.) Unix command sh:
Words of the form $'string' are treated specially. The word expands to string, with backslash-escaped characters replaced as specifed by the ANSI C standard.
