Re: [Cocoadialog-users] bash script example for inputbox or standard-inputbox?

[Mark A. S. <ma...@sp...>]

Well, this is more of a shell question than a CocoaDialog question.
It sounds like the heart of your question is regarding how to split a 
variable on newlines, yea?

If so, something like this should work for bash (disclaimer: This may 
not be entirely correct, there may be better ways, etc etc. ;)  I do 
most of my shell scripting with Perl.:
OLD_IFS="$IFS"
IFS=$'\n'
rv=($($CD standard-inputbox --no-newline))
echo -n "User pressed: "
echo ${rv[0]}
echo -n "User typed: "
echo ${rv[1]}
IFS="$OLD_IFS"

Now, note that ${rv[1]} will only contain the second line, so be sure 
to adjust that snippet accordingly if you want multi-line input (from 
the textbox for example).

Also, i believe there is a bug in standard-inputbox when the 
--string-output is given.  Hopefully i'll have time to look into it 
soon.  (I'm just pointing it out so you don't bang your head on the 
desk for hours thinking your script is broken if you try to use that 
option).
