nix:tldr:17330

This command is performing two actions:

1. mkdir -p ~/.config/nix:

   • mkdir is a command used to create directories in a file system.
   • -p is an option that allows the creation of parent directories if they don't exist.
   • ~/.config/nix specifies the path where the directory is created. ~ represents the user's home directory.

   The overall effect of this part of the command is to ensure that the ~/.config/nix directory exists. If it already exists, the command will have no effect.

2. echo 'experimental-features = nix-command flakes' > ~/.config/nix/nix.conf:

   • echo is a command used to print text or variables to the terminal.
   • 'experimental-features = nix-command flakes' is the text being printed by the echo command.
   • > redirects the output of the echo command and writes it to the specified file instead of printing it to the terminal.
   • ~/.config/nix/nix.conf specifies the path and filename where the text is being written.

   The overall effect of this part of the command is to create a file named nix.conf in the ~/.config/nix directory (created in the previous step), containing the line experimental-features = nix-command flakes.
