The available options are:
- --source-map Specify an output file where to generate source map.
- [string]
- --source-map-root The path to the original source to be included in the
- source map. [string]
- --source-map-url The path to the source map to be added in //@
- sourceMappingURL. Defaults to the value passed with
- --source-map. [string]
- --in-source-map Input source map, useful if you're compressing JS that was
- generated from some other original code.
- --screw-ie8 Pass this flag if you don't care about full compliance with
- Internet Explorer 6-8 quirks (by default UglifyJS will try
- to be IE-proof).
- -p, --prefix Skip prefix for original filenames that appear in source
- maps. For example -p 3 will drop 3 directories from file
- names and ensure they are relative paths.
- -o, --output Output file (default STDOUT).
- -b, --beautify Beautify output/specify output options. [string]
- -m, --mangle Mangle names/pass mangler options. [string]
- -r, --reserved Reserved names to exclude from mangling.
- -c, --compress Enable compressor/pass compressor options. Pass options
- like -c hoist_vars=false,if_return=false. Use -c with no
- argument to use the default compression options. [string]
- -d, --define Global definitions [string]
- --comments Preserve copyright comments in the output. By default this
- works like Google Closure, keeping JSDoc-style comments
- that contain "@license" or "@preserve". You can optionally
- pass one of the following arguments to this flag:
- - "all" to keep all comments
- - a valid JS regexp (needs to start with a slash) to keep
- only comments that match.
- Note that currently not *all* comments can be kept when
- compression is on, because of dead code removal or
- cascading statements into sequences. [string]
- --stats Display operations run time on STDERR. [boolean]
- --acorn Use Acorn for parsing. [boolean]
- --spidermonkey Assume input files are SpiderMonkey AST format (as JSON).
- [boolean]
- --self Build itself (UglifyJS2) as a library (implies
- --wrap=UglifyJS --export-all) [boolean]
- --wrap Embed everything in a big function, making the “exports”
- and “global” variables available. You need to pass an
- argument to this option to specify the name that your
- module will take when included in, say, a browser.
- [string]
- --export-all Only used when --wrap, this tells UglifyJS to add code to
- automatically export all globals. [boolean]
- --lint Display some scope warnings [boolean]
- -v, --verbose Verbose [boolean]
- -V, --version Print version number and exit. [boolean]

Specify `--output` (`-o`) to declare the output file. Otherwise the output
goes to STDOUT.
