I also didn't learn Unix this way, but I sure learned a lot more once I did.

- tomwheeler 3y agoIn addition to being informative, they're also sometimes funny. I remember that the HP/UX tunefs man page said, "You can tune a filesystem, but you can't tune a fish."
- jasomill 3y agoThe inability to tune a fish was first documented in the original 4.2BSD man page for tunefs(8), https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/man/man8/tunefs.8 https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/man/ma... and is still present in most BSD-derived tunefs implementations, e.g., https://man.freebsd.org/cgi/man.cgi?query=tunefs&apropos=0&sektion=8&manpath=FreeBSD+13.2-RELEASE&arch=default&format=html https://man.freebsd.org/cgi/man.cgi?query=tunefs&apropos=0&s... AFAICT, this restriction does not apply to versions of tunefs provided by System V and its derivatives, e.g., https://docs.oracle.com/cd/E86824_01/html/E54764/tunefs-1m.html https://docs.oracle.com/cd/E86824_01/html/E54764/tunefs-1m.h... As with many things in UNIX, the ability to tune a fish is implementation-dependent, and testing is recommended before using it in production on any given platform.
- somat 3y agoOne of my favorite man pages is openbsd's scan_ffs. mainly because it contains this pearl of wisdom The basic operation of this program is as follows: 1. Panic. You usually do so anyways, so you might as well get it over with. Just don't do anything stupid. Panic away from your machine. Then relax, and see if the steps below won't help you out. http://man.openbsd.org/scan_ffs http://man.openbsd.org/scan_ffs
