Comments on: ProcessBuilder and quotes http://blog.krecan.net/2008/02/09/processbuilder-and-quotes/ Short remarks from Java world Wed, 07 Jan 2009 03:28:59 +0000 http://wordpress.org/?v=2.7 hourly 1 By: Seth Tisue http://blog.krecan.net/2008/02/09/processbuilder-and-quotes/comment-page-1/#comment-547 Seth Tisue Wed, 20 Aug 2008 14:20:49 +0000 http://blog.krecan.net/2008/02/09/processbuilder-and-quotes/#comment-547 The purpose of the quotes was to prevent characters like * from being interpreted specially by the shell. Only the shell sees the quotes; the shell strips them out before passing the arguments to the rsync command. But ProcessBuilder doesn't use a shell; it runs the command directly. Since there's no shell involved, the quotes aren't needed, and if you include them, they will not be stripped out, causing the rsync command to become confused about your intentions. Why it would have worked on Windows with the quotes, I don't know. The purpose of the quotes was to prevent characters like * from being interpreted specially by the shell.
