[Bug]: steamcmd is unable to print app info with +quit in the start parameter

[HotoCocoaco]

User story

I was trying to update the server with update ./tf2server update command. But failed.

Game

Team Fortress 2

Linux distro

Ubuntu 22.04

Command

command: update

Further information

scripts log

UPDATE: INFO: Using anonymous Steam login
UPDATE: PASS: Checking local build
UPDATE: FATAL: Checking remote build
UPDATE: INFO: LinuxGSM version: v23.5.3

It seems that steamcmd is not willing to print app info with +quit behind, making remotebuildversion null value.
Full command line: steamcmd +login anonymous +app_info_update 1 +app_info_print 232250 +quit
Result:

Redirecting stderr to '/home/tf2server/.local/share/Steam/logs/stderr.txt'

...... and more

I have modified core_steamcmd.sh to echo debug the value that making sure remotebuildversion is null.

Relevant log output

No response

Steps to reproduce

1. Run ./tf2server update.
2. BOOM.
3. Run steamcmd with +quit. BOOM.
4. Without +quit. OK.

the +quit command is required to correctly exit steamcmd. This is not an issue that I have come across or others have been reporting. I will close for now
