I occasionally have to re-install operating systems on the various linux machines which I manage. Every time I do this, I have to copy the `.bashrc` file to a USB drive before wiping the old system, and then put it back after I've installed a new system. (And perhaps edit it if something is no longer compatiable.)

This is annoying, and I usually stick to one version of a Linux OS and install it on most of my machines, so I've been trying to store my `.bashrc` content in a new file inside my Dropbox folder.

For example, I have put `HISTTIMEFORMAT="%F %T "` in a file named `mybash` inside my Dropbox folder.

What do I need to put inside my `.bashrc` file to "load all the stuff from the `mybash` file"?

I tried this, but it didn't seem to work?

```
# Load bash custom files
if [ -f /home/user/Dropbox/mybash ]
then
    . /home/user/Dropbox/mybash
fi

```
