Script to copy Google Chrome profile to ram and after it closes copy back to disk. It does not sync often. Be aware: you can lose your work, login and also sync your profile with a Google account.

README.md

google-chrome-ram.sh

How to run

Download google-chrome-ram.sh make it executable and call it with or without a profile name.

If you call it like this:

$ ./google-chrome-ram.sh

It will use default as the name of the profile.

If you call like this:

$ ./google-chrome-ram.sh work

It will use work as the name of the profile.

You can open as many profiles as you want at the same time. One does not change the other.

How it works

1. Copy your profile to /dev/shm/google-chrome-XXX (/dev/shm is a RAM disk)
2. Open google-chrome-stable pointing to that directory
3. After closing Google Chrome copy back to ~/.local/google-chrome/XXX

WARNING

This script does not sync often, you can and will lose your work if you close without waiting it to sync back.

Be aware.

Also, sync your profile with a Google account.
