ubuntu - How to know what version of UglifyCSS was installed? -

-

i has installed uglifycss globally command:

npm install -g uglifycss

how can current version of installed uglifycss?

p.s.

version of uglifyjs check command:

uglifyjs -v

but when try similar command uglifycss:

uglifycss -v

i had error:

unable process "-v" error: enoent, no such file or directory '-v'

same error when try -v , --version

there no command line option installed version. valid options --max-line-len, --expand-vars, --ugly-comments , --cute-comments.

however, can run npm list -g or npm list list of installed packages , version numbers. or can add package name query specific package, e.g. nmp list uglify-js.
