The openSUSE guys worked on the same problem (https://bugzilla.novell.com/show_bug.cgi?id=435160), going from a few seconds down to 700ms and got told they'd need to do better :) In the end they added a COMMAND_NOT_FOUND_AUTO variable, disabled by default, to do the slow search, and the standard behaviour became to print a message similar to Command not found.

I agree, this feature isn't useful on linux. In 100% of cases it got engaged for me it was a result of typo. It would be useful to have a command that finds the port name(s) by the command name when needed though. Today, for example, while searching for package that has a command 'svlc' I do 'cd /usr/ports make search key=svlc' and it finds nothing instead of finding multimedia/vlc. make search seems to search through package names, dependency names, but not command names for some reason.

It annoys me far more often than it actually helps me, because more often than not the missing command is a typo, *not* an attempt to run a command I don't have. I.e., if I type mmap instead of nmap, I get: mwm@IPGhosterCrawlerI:~$ mmap No command 'mmap' found, did you mean: Command 'jmap' from package 'openjdk-6-jdk' (main) Command 'jmap' from package 'openjdk-7-jdk' (universe) Command 'gmap' from package 'gmap' (multiverse) Command 'gmap' from package 'scotch' (universe) Command 'tmap' from package 'emboss' (universe) Command 'smap' from package 'slurm-llnl' (universe) Command 'pmap' from package 'procps' (main) Command 'moap' from package 'moap' (universe) Command 'umap' from package 'libunicode-map8-perl' (main) Command 'map' from package 'sgt-puzzles' (universe) Command 'amap' from package 'amap-align' (universe) mmap: command not found That said, this seems to require modification to the ports system to generate a database for it. And having a command in the base system that I can feed a command (or better yet, file - I need libraries almost as often as I need commands) name to and it tells me what package/port to install would be useful. Again, I hope a FreeBSD implementation would be a bit more constrained, and *not* list similar commands. bash and zsh already have command_not_found handlers. I don't really object to that functionality to sh and tcsh. Just *don't turn it on by default*. I don't think I'd even object to setting those handlers in /usr/share/skel. Of course, I might turn around and ask that we add support for command correction ala zsh to sh tcsh via those hooks if they get added. mike -- Mike Meyer m...@mired.org http://www.mired.org/ Independent Software developer/SCM consultant, email for more information.

Auto-install would be problematic, but the feature being discussed here does not require installation. Just better error messages. My objection was not due to misunderstanding about auto-install. I find the feature annoying - spewing a bunch of crap at me because of a typo.

In this case, a better UI might be to separate the typo handling from the package reference, so that you would see something like this: $ mmap mmap: command not found Perhaps you meant one of: jmap, gmap, tmap, smap, (8 others) That way, if you did really mean jmap, you could try again and see $ jmap jmap: command not found Try installing one of the following packages: java/openjdk-6-jdk java/openjdk-7-jdk I agree also about the convenience of having a tool that can identify the port/package that would install a particular library (or other file). I too have run into the situation where I need a particular library and can't figure out what the package is called. bash and zsh already have command_not_found handlers. I don't really object to that functionality to sh and tcsh. Just *don't turn it on by default*. I don't think I'd even object to setting those handlers in /usr/share/skel. How about if it's on by default (in the default /etc/cshrc) but very easy to turn off? The primary point of such a feature is to help people new to FreeBSD. Someone who sits down at a new FreeBSD installation and wants to run 'nmap' can then get up to speed a lot more quickly, since they'll be pointed at the right package right away. Of course, I might turn around and ask that we add support for command correction ala zsh to sh tcsh via those hooks if they get added. grin Tim ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

How about if it's on by default (in the default /etc/cshrc) but very easy to turn off? Actually, that's my biggest gripe about Linux systems. They set things in /etc/* shell profiles that *can't* be turned off in user rc files, because the ones in /etc run last. (And usually more than once. Idiots.) If you don't have root, the best way to deal with them is to install a shell that won't run things in /etc. If you have root and turn them off in /etc, you turn them off for everyone, which may well piss someone off. Which makes me think that setting user preferences via things in /etc instead of /usr/share/skel is a dangerous path to start down. That means users can *always* fix it, and it will also work for shells that the Linux way won't work for. Is there something wrong with using /usr/share/skel? Doesn't it get used when the install scripts create users? How appropriate. There are explosives going off outside my window. mike -- Mike Meyer m...@mired.org http://www.mired.org/ Independent Software developer/SCM consultant, email for more information.
