nix-shell: Start with expression in `default.nix` in the current directory.
$ nix-shell ${default-nix}
try on your machine
The command "nix-shell ${default-nix}" is used in the Nix package manager to create an isolated shell environment with the dependencies specified in the "default.nix" file.
Here's how the command breaks down:
- "nix-shell" is the Nix command used to start a new shell environment.
- "${default-nix}" is a variable placeholder that is expected to be replaced with the path to a "default.nix" file. This file contains the package definitions and dependencies for the shell environment.
When you run this command, Nix looks for the "default.nix" file and uses its content to create a new shell environment. This environment will have all the dependencies available, making it easy to work on a specific project with the required software packages and versions.
By using "nix-shell", you can enter this isolated environment and have all the necessary tools and dependencies set up automatically, avoiding conflicts with other packages and ensuring reproducibility across different machines.
