I'm a new to UNIX/LINUX. I just put cygwin on my laptop and I can navigate around the directories, but I can't open files (.doc, .ppt, .html or .exe). Is there an explicit command to do this? I know that in Solaris when it does not recognize the file, it brings up the list of available viewing applications, much like Windows, but I've looked through all my UNIX books and can't find a thing about opening files. It's mostly about navigating through directories and cmds and flags for display of info. I know cygwin is a LINUX emmulator, but I have a feeling that this is not specific to UNIX/LINUX. It's either cygwin or it's my lack of knowledge. Please let me know if you've had similar problems or if you see blatant stupidity here. It's possible. I've just migrated to UNIX from a life of Window$ and I'm admittedly still green.--thanks--AJ
