Solution

The command that efficiently reads the list of package names from "packages.txt" and installs them is:

xargs -a packages.txt apt-get install -y

This command uses xargs to read the file (packages.txt) and passes each line as an argument to the apt-get install command. The -y flag is used to automatically answer yes to prompts and run non-interactively.
