My favorite man page is scan_ffs.

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.
- smcameron 4y agoHa. I wasn't familiar with scan_ffs, so I googled it. Given what it does, or purports to do, yeah, a first step of "Panic" makes total sense. Reminds me of something which happened early in my career. An older, wiser coworker came by and said, "You won't believe what I almost did. I was installing a new disk on cyclops (our main NFS server), and I almost typed 'newfs /dev/sda' instead of 'newfs /dev/sdb'" (this was on SunOS 4, iirc). Then he went back to his office, hit return a couple times and... he had left "newfs /dev/sda_" sitting there on the command line. Panic ensued. We recovered from backup tapes.

- teddyh 4y agoFor those who are wondering: The Linux equivalent is “findsuper”, which is from the e2fsprogs package, but the “findsuper” command is not normally built and installed, so when you need it, you will have to download the e2fsprogs source and compile findsuper yourself. An unnecessary pain at the worst possible time, sadly.
