This may be a TOTALLY trivial question (and maybe inappropriate for this list), but I don't know where else to ask it: On my Mac I've got this wonderful command line utility that opens documents with the program that is associated to them in the Finder (the graphical file manager) like they were clicked in the file-manager. For instance: if I type open testdocument.doc it opens the file with Word or OpenOffice (whatever is associated with the document type .doc). This is quite convenient (don't have to leave the shell to open a document) My question: Is there a similar command on CentOS (or more specifially GNOME, because obviously it has to take the associations from some kind of GUI-filemanager)? I was looking around, but this is the kind of question where googling doesn't turn up anything useful unless you know the name of the command. Thanks
