I have deliberately configured the file system of my RaspberryPi (Raspbian - Jessie) to be read only. One of the things that's not (yet) working is tab (aka auto) completion in bash, where I often get the following error:
bash: cannot create temp file for here-document: Read-only file system
Much on-line discussion focuses on how to fix file system problems manifesting themselves with this error. I'd like to adjust bash instead. Where is it trying to create this temp file and how can I redirect it to create that file in /tmp (which is mounted with tmpfs)?
