Run google-chrome with flags on Android

There are command line flags (or "switches") that Chromium (and Chrome) accept in order to enable particular features or modify otherwise default functionality.

Chromium Command Line Switches

Run Chromium with flags

Tried Chrome 41.0.xx and Chromium 43.0.xxx shell with:

# echo "chrome <flags>" > /data/local/tmp/android-webview-command-line
# echo "chrome <flags>" > /data/local/tmp/content-shell-command-line

Any idea how to run chrome with flags on Android or directly add these into default profile.
