#!/bin/sh
 
# This script lists user defined search engines in Chromium.
# It replaces {inputEncoding}, which appears in some search engine definitions, with
# UTF-8, {google:baseURL} with the Google URL, and omits other such tokens.
 
# Location of Chromium's 'Web Data' SQLite3 file
CHROMIUM_WEB_DATA="$HOME/.config/chromium/Default/Web Data"
 
# Location to create temporary copy of 'Web Data', since the database is locked while
# Chromium is running
COPY=$(mktemp)
