# This script will spawn a new Chrome process restricted to a profile that
|
||
|
|
# is created on demand and (optionally) deleted on exit. If a root profile
|
||
|
|
# directory is given, it will be used as the template for the newly created
|
||
|
|
# profile.
|
||
|
|
#
|
||
|
|
# NOTES:
|
||
|
|
#
|
||
|
|
# Chrome spawning takes place irrespective of any currently running Chrome
|
||
|
|
# processes. The script will always spawn a new Chrome process.
|
||
|
|
#
|
||
|
|
# If a root profile directory is not configured/passed-in as an argument, the
|
||
|
|
# created profile will be a fresh, first-time profile that does not contain
|
||
|
|
# any configuration data or extensions that may be present in a different
|
||
|
|
# profile for the same installed Chrome browser.
|
||
|
|
#
|
||
|
|
# To create a root profile, execute `chrome-private.sh --name name --keep',
|
||
|
|
# and after installing extensions and modifying browser configuration, you
|
||
|
|
# can copy/rename its directory and set it as ROOT_PROFILE_DIR (or pass it
|
||
|
|
# as an argument with --root-profile).
