Where do they come from. Can it be that something here is interpreted in strange way? Can be some kind of weird new line conversion in the output that cause the shell to go south? Any strange settings in ENV defining terminal settings? Can you do any python based output? <blockquote cite="mid:530DDD52.8000102@damascusgrp.com" type="cite"><tt> See "ipa <COMMAND> --help" for more information on a specific command. Script done on Wed 26 Feb 2014 07:20:28 AM EST #</tt> It looks like something is behaving differently when input comes from a tty vice when it doesn't. For grins, I did the same thing using "ipa host-find zw129.damascusgrp.com" and got basically the same result -- an empty log first, then successful completion (including expected results) using the -c option.
