Round about Linux kernel 1.1, I once ran into a problem with a file copy not actually completing. The inodes weren't updated. Something. I can't even remember. But I read about sync. And I started using it at the end of every set of commands I issued from the command line. From the virtual terminals that I haven't used in years. Maybe it was from the glowing green AT&T dumb terminal in my parents' basement with the lights off and tin-foil over the windows so no light got in, and from which I never emerged. Sync fixed my problem. Some point 10 years ago it become pointless. But I can't let go. Now, I don't feel complete if I don't sync. I HAVE to sync. It makes me feel satisfied that my operations are complete. No sync, no satisfaction. But there's no point anymore. It does nothing for me. But I still do it. I'm compelled. Its my favorite fucking command. I love it. I can't let go. Why must I sync?
