/run/user/1000: What to do with it?
(lemmy.ml)
My main question is about /run/user/1000:
- Should I avoid touching it?
- Could I delete it?
- Is there something wrong with it?
Background: I'm fairly new to Linux and just getting used to it.
I use fsearch to quickly find files (because my filenaming convention helps me to get nearly everything in mere seconds). Yesterday I decided to let it index from root and lower instead of just my home folder.
Then I got a lot of duplicate files. For example in subfolders relating to my mp3 player I even discovered my whole NextCloud 'drive' is there again: /run/user/1000/doc/by-app/org.strawberrymusicplayer.strawberry/51b78f5c/N
Searching: Looking for answers I read these, but couldnt make sense of it.
- https://unix.stackexchange.com/questions/162900/what-is-this-folder-run-user-1000
- https://forums.linuxmint.com/viewtopic.php?t=412850 So if its a bug with flatpaks I'm inclined to delete a certain db at ~/.local/share/flatpak/db
Puzzled:
- Is this folder some RAM drive so my disk doesnt show anything strange? Because this folder doesnt even show up at the root level.
- Are these even real? Because the size of it (aprox 370 GB) is even bigger then my disksize (screenshot).
Any tips about course of (in)action appreciated.
@joeldebruijn@lemmy.ml the /run/user/1000 directory is an in-memory file system of a fairly small size. The operating system creates it for you to store certain things that are for your user account only. The permission settings on this directory forbid any other user on the system (except for "root") to see what is inside. This makes it safe to store secret information that only you should know.
One typical example of something stored in this directory would be your plain text (unencrypted) password database if you use a password manager. No other user but you (and "root") can see it, and it is in-memory only so it is not accidentally copied to your persistent memory (HDD or SSD disk drive) where it might be removed and read by hackers if someone steals your computer from you. At the same time, any program running on the system that was launched by you and only you has access to your passwords so you don't need to remember passwords for everything. (Actually it is a socket to a server containing your unencrypted password database in memory, it is probably not actually a file in that directory.)
Other things that go in this /run/user/1000 directory are socket connections to the desktop bus (allows for things like copy-and-paste or drag-and-drop to work between programs), socket connections to your audio mixer (allows you do things like to listen to music and do video chat at the same time), and a record of what external media devices you have connected to the computer which you are using via GVFS, and so on.
Also, the number 1000 is your user ID number assigned to you by the operating system. If you create other accounts, they will have ID 1001, 1002, and so on, and each of them will have a directory with that number created in the /run/user directory for them when they login.
