More to the point, opening a directory for writing is an error. Since you normally use an editor to modify files, instead of just viewing them, it makes sense that vi warns you that you won't be able to write back your changes. It would not make sense for tail to warn you, because it only reads files. wopr:~$ perl -e 'open SPORK, ">tmp/" or die "$!"' Is a directory at -e line 1. wopr:~$ perl -e 'open SPORK, "tmp/" or die "$!"' wopr:~$ (See also "man 2 open".) -- Matthew Hunt <mph@astro.caltech.edu> * Clearly there are more things in the http://www.pobox.com/~mph/ * heavens than anyone anticipated. -enp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
