Quick Tip - Share steam library with multiple Linux accounts and systems

If you use Steam on Linux one of the annoying things I’ve found is that unlike on Windows, Steam for Linux installs
to your $HOME directory. This means every user will have their own Steam installed and what’s more their own games
installed. So on a shared system you might end up with the same games being installed multiple times.

I recently discovered Steam has a feature that allows you to install games to a alternate location called Steam
Libraries. This feature allows you to create a Library at a new location such as an alternate harddrive or partition if
you don’t like where Steam installs games by default. What I thought I’d try doing was creating a new user group on my
system which I called “steam” and I added all the users on my system which used Steam to this group. Then I created a
shared directory on my system called /steam-library which I then set the permissions to allow reading, writing and
executing files from this directory to anyone in the steam group.

Next I launched Steam and added /steam-library as a new Library in Steam and installed games to this location. After
installing the games you tell all other users who use Steam on this computer to do the same. If a game they want to
install is already in the Library, it’ll just appear in their account, no unnecessary downloading.

Steam Libraries

Quick Steps

mkdir /steam-library
groupadd steam
chgrp steam /steam-library
chmod 770 /steam-library
useradd -G steam your_user
# add /steam-library to steam on all pc's and user accounts

For those who have multiple computers. You can share /steam-library as an NFS share over the network and mount it
on your other computers too. Having a single point where your shared library lives will save you from having to
download the same files multiple times over the internet.
