Hmm, if you want to replace ' ' with '-', you can do it as follow:

$ for f in `ls | grep ' ' | tr ' ' '-'`; do echo "@$f@"; done
@foo-bar@
@foo-snafu@

For printing both original and new file names:

$ ls | grep ' ' | perl -ne 'chop; print "\@$_\@"; s/ /-/g; print "\t\@$_\@\n";'
@foo bar@ @foo-bar@
@foo snafu@ @foo-snafu@

Hope this help,
