Compiling the Brave Browser (based on Chromium) on Linux can take a really long time and so most developers use sccache to cache objects files and speed up future re-compilations.

Here's the cronjob I wrote to seed my local cache every work day to pre-compile the latest builds:

30 23 * * 0-4   francois  /usr/bin/chronic /home/francois/bin/seed-brave-browser-cache

and here are the contents of that script:

#!/bin/bash
set -e

# Set the path and sccache environment variables correctly
source ${HOME}/.bashrc-brave
export LANG=en_CA.UTF-8

cd ${HOME}/devel/brave-browser-cache

echo "Environment:"
echo "- HOME = ${HOME}"
echo "- PATH = ${PATH}"
echo "- PWD = ${PWD}"
echo "- SHELL = ${SHELL}"
echo "- BASH_ENV = ${BASH_ENV}"
