Why are git commands like push printing "\S Kernel on an" to the terminal each time i run-CodePudding

When I run git, it is printing some odd text to the terminal that seems unrelated to the command. For example, with git push:

$ git push
\S
Kernel  on an 
Everything up-to-date

I've noticed it only happens when my commands involve the remote repo.

Is this a bug? Something I should worry about?

Here is some additional information about my environment:

$ echo $0 $SHELL
-zsh /bin/bash

$ git --version
git version 2.35.1

$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

$ git remote -vv
origin  <redacted>:<redacted>.git (fetch)
origin  <redacted>:<redacted>.git (push)

$ git push --verbose
Pushing to <redacted>:<redacted>.git
\S
Kernel  on an 
To <redacted>:<redacted>.git
 = [up to date]      master -> master

CodePudding user response：

The text

\S
Kernel  on an \S

is almost certainly the ssh pre-login banner configured for the ssh daemon on the server you are pushing to. It is defined on the server in the /etc/issue file.

It appears to be misconfigured, as the login banner is probably intended to show something like:

Redhat blah blah blah
Kernel 2.6.11.12 on an i486

You can verify this by ssh'ing to the server directly, which is more or less what @torek suggested.
