pipe output from find -type f through basename (in a script only) and then through uniq -d

E.g. 1.sh:
Code:
#!/bin/sh
find -type f | while IFS= read vo
do
echo `basename "$vo"`
done

Then
Code:
$ ./1.sh | uniq -d

This is to handle files with spaces in filenames (IFS= removes internal space field separator)

I dont know how to make this in one line (becouse of besaname syntax, it cannot read filenames from stdin)

By the way, to compare files by content you can use cmp command (but you need to compare each file with each).
