will do the replacement automatically.  However, it'll also change some
lines that it shouldn't.  The changes are written into
After that, we'll want to compare the changes made to ensure that we
didn't change anything that we shouldn't have.  With the stock CircleMUD
world, there are two lines that are modified that shouldn't be (one in
25.mob and one in 54.mob) that I saw.  Needless to say, altering those two
lines is much easier than altering a magnitude more for the same effect.

Now the trick is to get this to run automatically and recursively on all
mob files.  How you do this depends upon your shell.  With BASH, and thus
probably most shells,

    % for f in *.mob ; do sed s/"^8 8"/"9 9"/ $f > $ ; done

but in tcsh, you'll do,

    % foreach f ( *.mob )

and when you're prompted with "foreach?" do,

    foreach? sed s/"^8 8"/"9 9"/ $f > $
    foreach? end

If you don't care about errant changes, then just copy all of the .new
files over the originals.  If you do want to double-check, run "diff -u
xxx.mob" to get a list of all changes (you might want to pipe
this to 'less' or some other pagination program, since the output'll be
over one page long in most cases).  Note the changes (or save the output
of 'diff' to a file), copy over the .new file, and manually revert bad

Like I said, there were only two in stock CircleMUD, and I think the only
effect of replacing those "8 8"s was raising a mobile's level and thac0 by
one.  That's probably not a very big deal.
