Programs like Playnite or Depressurizer can export your entire library as a plain text list of App IDs.

Using Depressurizer:

Example games.txt file:

730
570
292030
10
4000

Pro: No command line.
Con: Requires pre-existing backups; not a true "list install" from online.

SteamCMD is the backbone of any serious steam combo list install. Unlike the graphical Steam client, SteamCMD can accept scripts and batch commands.
