vscode devcontainer "postCreateCommand": "alias 'll=ls -alF'"

Question

I am using a default MS configuration (in Visual Studio Code -> "Remote-Container: Add Development Container Configuration Files...") and added the following to the

.devcontainer/devcontainer.json

"postCreateCommand": "alias ll='ls -alF'"

Using the command manually in the vscode terminal after creation yields the desired ll.

How do I have to specify the "postCreateCommand"-entry to get the alias?

Correct me if I'm wrong. You want to have the ll alias available inside the container. You can achieve this by adding this line to the Dockerfile:
RUN echo "alias ll='ls -alF'" >> /etc/bash.bashrc

If you want to leave the Dockerfile as is, you can also add it to the postCreateCommand like this: "postCreateCommand": "echo alias ll=\\'ls -alF\\' >> /etc/bash.bashrc" This will add the alias directly to the system-wide bashrc file. The alias will be available in all interactive shells started within the container.

If you run into a "Permission denied" then you can also do this:
"postCreateCommand": "echo alias ll=\\'ls -alF\\' >> /home/vscode/.bashrc" credit to @Damian for this one.

I tested the `postCreateCommand` - works like a charm. Thank you! – BadAtLaTeX Jul 19 '20 at 19:32
I get an error ```/bin/sh: 1: cannot create /etc/bash.bashrc: Permission denied``` – Damian Jun 20 '23 at 01:46

But this works: ```"postCreateCommand": "echo alias ll=\\'ls -alF\\' >> /home/vscode/.bashrc",``` – Damian Jun 20 '23 at 01:53
In case it helps anyone, to avoid needing root permission, I used ~/.bash_aliases to accomplish this. – user317808 Jun 26 '23 at 18:27
