Hi folks:

I=92m trying to emulate how iTunes changes some names of directories it =
creates based on names of artists.  For example, albums by the group =
R.E.M. are stored in a directory it creates called R.E.M_ =20

The final full-stop is replaced with an underscore, I assume to avoid =
complications in the unix filesystem.


This works:

JUNK=3DR.E.M.
print ${JUNK}| perl -p -e 's|\.$|_|g=92

It returns
R.E.M_


But if I try to do this: =20

print ${JUNK/\.$/_}  =20

it returns              =20
R.E.M.

I assume I am not using the correct regexp.  What do I need to do to get =
this working?

Thanks in advance.

Bill Scott=
