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

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

"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:

1. Adding this to the Dockerfile:
   RUN echo "alias ll='ls -alF'" >> /etc/bash.bashrc

If you want to leave the Dockerfile as is:

2. Use the postCreateCommand from vscode (If you don't want to change the dockerfile): "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.

   OR

   "postCreateCommand": "echo alias ll=\\'ls -alF\\' >> ~/.bash_aliases" This adds the alias to a separate file specifically for aliases and doesn't require root access in the container. Be aware: You'll need to source the .bash_aliases in .bashrc or else this won't work.(credit: @user317808)

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