zsh does that by default:
$ rm * .jpg
zsh: sure you want to delete all the files in /tmp [yn]?
(disabled with "setopt RM_STAR_SILENT")
Also in tcsh, though not enabled by default there:
> set rmstar
> rm *
Do you really want to delete all files? [n/y]
(they match on "rm *" or "rm dir/*")
For bash, you can try this approach:
