• export $PATH=$PWD/depot_tools:$PATH (shell specific)
• fetch --no-history chromium --nosvn=True
• cd src
• mkdir -p out/release
• echo 'import("//build/args/headless.gn")' > out/release/args.gn
• echo 'is_debug = false' >> out/release/args.gn
• gn gen out/release
• ninja -C out/release headless
• ln -s ~/chromium/out/release/headless /usr/local/bin/headless-chromium

Usage

• headless-chromium ...
