Seems I've forgotten to reply-to-all (sorry peeps) ... OK. I've clearly not explained myself. And I know Windows isn't Mac/*nix/etc. I know I can rename the files back and forth all day long. That is EXACTLY what I'm already doing. It is plainly a stupid way to go. I know I could type lovely long command lines - but why? I want to just double click a file and get it to do what I want. And I can't seem to find even the simplest questions. If I could find the mechanics that associates a file extension to a program, I'd be onto a winner with the 'open -a ...' option. 'open -a LibreOffice.app --args --calc /development/_data_canonical/acczuk.tsv' works perfectly from the command line. It does exactly what I want. So, how do I make THIS the command that is ran when I double click a file? -- Richard Quadling | richard@fantasyshopper.com | http://www.fantasyshopper.com Fantasy Shopper <http://www.fantasyshopper.com/> http://www.fantasyshopper.com/ Fantasy Shopper: a fun new website where you can fulfill all your shopping fantasies!
