html-minifier – HTML minifier with lint-like capabilities

Synopsis

html-minifier [OPTIONS] [FILE(s)]

Description

HTMLMinifier is a highly configurable, well-tested, Javascript-based HTML minifier, with lint-like capabilities.

Usage

If no input file(s) specified then STDIN will be used for input.

If more than one input file specified those will be concatenated and minified together.

When you specify a config file with the –config-file option (see /usr/share/doc/nodejs-html-minifier/sample-cli-config-file.conf for format) you can still override some of its contents by providing individual command line options, too.

When you want to provide an array of strings for –ignore-custom-comments or –process-scripts options on the command line you must escape those such as –ignore-custom-comments "[\"string1\",\"string1\"]"
