Description

As of 2/2/25
In the Dockerfile for openworm,

RUN echo '\n\nalias cd..="cd .."\nalias h=history\nalias ll="ls -alt"' >> ~/.bashrc
doesn't seem to update bashrc properly

Running source ~/.bashrc throws the below error
root@1a2cf2d71234:/# source ~/.bashrc
bash: nnalias: command not found

As the aliases aren't written into the bashrc correctly

Instead, using -e interprets the string properly
RUN echo '\n\nalias cd..="cd .."\nalias h=history\nalias ll="ls -alt"' >> ~/.bashrc

~/.bashrc with -e
alias cd..='cd ..'
alias h='history'
alias ll='ls -alt'

~/.bashrc without -e
\n\nalias cd..="cd .."\nalias h=history\nalias ll="ls -alt"

Research direction

Start with the RUN echo command in the Dockerfile and reproduce the ~/.bashrc result by sourcing it in the container. Compare the escaped newline handling with and without echo's -e option; done means the aliases load without a source error.
