'set' and 'echo'). Moreover, I don't need inline help every time I make real mistake, obviously... I see, that command built-ins have '--help' option. This is not unified way: 1. no '--help' for syntactic statements like 'for', 'if'. 2. With '--help' there is no clarity that this is sure built-in When I type 'help COMMAND' I am sure that this is help about built-in. When I type 'COMMAND --help' I'm not sure if this is built-in or not (maybe there is no such built-in and this is help about executable util). > >> >> Btw, if someone is interested, I decided to look at 'fish' because of >> course 'bash' scripting is horrible!

I already did. As was said, it would be good to have 'VAR=x COMMAND' syntax to define temporary variables just for one command. Secondly, it would be good to have 'help COMMAND' to get inline help on topic, not in browser, not in man page, just on STDOUT. And thirdly, no need (and in fact is nagging) to get inline help on every error. If isn't yet, there should be an option to turn it off. > >> >> >> >> ------------------------------------------------------------------------------ >> One dashboard for servers and applications across Physical-Virtual-Cloud >> Widest out-of-the-box monitoring support with 50+ applications >> Performance metrics, stats and reports that give you Actionable Insights >> Deep dive visibility with transaction tracing using APM Insight. >> http://ad.doubleclick.net/ddm/clk/290420510;117567292;y >> _______________________________________________ >> Fish-users mailing list >> Fish-users@lists.sourceforge.net >> https://lists.sourceforge.net/lists/listinfo/fish-users > > > > > -- > Regards, > Siteshwar ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ Fish-users mailing list Fish-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/fish-users
