This whole thing involves about a hundred bazillion dangerous, presumptuous “do shell script” calls. Instead of using AppleScript’s built-in file access routines, the author has chosen to use shell scripts and the “echo” command to perform all of his writes. For all of his reads, he uses a combination of the UNIX “cat” command with the “sed” and “tail” command. For each line of the original Bookmarks line to be read, he cats the *entire* file and pipes the result through sed and then tail. Seeing this kind of stuff makes me wonder whether half of my hard drive was deleted and I just haven’t found out yet.
