i'm afraid the best (/weirdest) i can do is:

find /dosdir -print | `sed 'h;s/%20/ /g;s/%40/@nospam./g;t c;d;:c x;s/.*/mv & /;G'`

(i can explain the sed further if anyone really wants to know ;)


as much as i hate to admit it, perl's 's///e' is really useful for
this:

find /dosdir -print | \
 perl -ne 'chop;$a=$_;rename $a,$_ if s/%(\d\d)/chr hex $1/ge'

which does general-case "%.." replacement



of course, what alex should have done was:
 smbtar -s hismachine -x hisshare -t hismachine.tar .
