I reviewed this book and I found a looooot of bugs in there. Nobody bothered to check if all queries are ok.
Examples? Here you are:
command: rmdir -r newdir
should be: rm -r newdir
another here: SELECT name FROM sys.obj$ WHERE obj#='4916681';
should be: SELECT name FROM sys.obj$ WHERE dataobj#='4916681';
it is only a couple of first pages. I am scared what gonna be later...
