Linux file names

You work with a number of linux/unix/whatever tools every day. How many of them break/require special handling when you have file name with spaces?

I fucking hate niggers who feel the need to implement their own broken argument parsers because of muh bloat. Nobody gives a shit if your binary is slightly larger or requires some .so, but they give a shit if your broken garbage can't handle --, doesn't respond to --help or -h and thinks -ass is a single flag.
