Example
[ alias ]
ignored = ! git ls-files --others --ignored --exclude-standard --directory \
&& git ls-files --others -i --exclude-standard
Shows one line per file, so you can grep (only directories):
$ git ignored | grep '/$'
.yardoc/
doc/
Or count:
~$ git ignored | wc -l
199811 # oops, my home directory is getting crowded
