This is possibly the only situation where the DOS command prompt beats 
the Linux / bash one.

 From memory, in DOS:

ren *s01* *s02*

...or...

ren *.htm *.html

Done.




Pathname Expansion in bash, nice as it is, will never allow this to happen.

It will expand "*.htm" to a list of all files that match the pattern, 
then pass that list to "mv" or "ren", making it impossible to determine 
the wildcard(s) used and their placement.

Quoting parameters helps, but then it's not like DOS. Disabling Pathname 
Expansion is possible, but since it's also useful, don't want to do that 
either.
