Java File IO getCanonicalFile() handling Linux Symbolic links
807588Apr 28 2009 — edited Apr 29 2009Does anyone have any experience using the File.getCanonicalFile() method. I would prefer to use the getCanonicalFile() to obtain the real file pointed to by a symbolic link, rather than the Linux "ls" command.
I currently check for any changes by executing a "ls" every second,when I test the getCanonicalFile() method, I see he doesn't seem to keep up with the real situation on the FileSystem ?
Example:
