SSH -> something like profile, .bashrc

Hi there,

I’m new to the WD EX2 Ultra. Already have a ChRoot on USB but for normal usage i’ve a question.

I’m using the SSH quite often. But i’m not able to find some file which is still available after a reboot (except on HDD/USB)

Want to install a small script for exporting and alias, that i can use the bash (or sh) more comfortable.
Any ideas where i can store this script//file and it will survive a reboot?
