If by 'name' you mean the complete path, then of course they
have to be different, otherwise there's only one name.

Apart from that, you can have 

/dir1/file.dat
/dir2/file.dat

pointing to the same inode, and hence the same file,
and also

/dir/file1.dat
/dir/file2.dat

can point to the same inode, and the same file.

On the command line, the commands are 'ln' to create a new link,
and 'rm' to remove one.

  int link (const char *oldpath, const char *newpath);

and

  int unlink (const char *path);

both declared in <unistd.h>
