Re: [Cocoadialog-users] Bourne Shell Script Equivalent to Perl Script Sample for CocoaDialog Dropdown

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

There isn't such a flag. But if we look at this example: 
http://cocoadialog.sourceforge.net/examples/fileselect.sh.txt
there's a 'while' loop in there that iterates over every line of $rv, 
each containing a file path.  It would be trivial to add a counter 
variable in there to count the number of files.

Surely there's some sort of shell trick to count the number of 
newline-separated entries in $rv if you don't want to loop over it.  I'm 
not much of a shell coder though, so unfortunately I can't tell you how 
to do this (or confirm that it's definitely possible).

In case it helps, in Perl you can just do: scalar( split /\n/, $rv );
to get the number of files listed in $rv (a return value from cocoadialog).
