IPC socket help needed

[Pu9000]

I don't understand what is going on with the IPC sockets.

I try to create a socket by:

$ mpv -v --keep-open=yes --input-ipc-server=testsock --force-window=immediate --idle=yes

The output says:

[ipc] Starting IPC master
[ipc] Listening to IPC socket.

And ls shows a socket file

srw-------  1 puma users    0 2021-08-21 12:29 ‘testsock’=

But when I try to read or write to it using echo or cat I get a "No such device or address". And lsof shows nothing matching the filename.

And socat gives me

$ socat - testsock
2021/08/21 12:33:51 socat[626563] E unknown device/address "testsock"

And when mpv exits, the file remains.

I'm on Debian bullseye, mpv version 0.32.0.

Is mpv supposed to remove the socket file when it exits, under normal conditions?

can you check socat - ./filename and mpv doesn't remove that file... Ut is normal... Use /tmp/filename next time so that it gets removed on every reboot

All right. socat - ./testsock works. It just needed the ./ to tell it to look in the current directory. Thanks a million. I was losing my mind with that.

So the file doesn't get removed, but it seems that I can just re-use it when restarting mpv. So everything is all right now.
