Help to hide shell terminal and run prompt program after ssh login for specified user
Hey guys,
I have some task from my office to lock user on the specified directory after the user logged on using ssh. And then run prompt program to fill the required information. Yeah, just like an ATM system.
My question:
How could I do those?? AFAIK I have to edit the ~./bashrc. But the problem is it's only for several users.
And how to make an interactive shell prompt? Like an ATM prompt system.
Thanks for your attention.

git-shell
GIT-SHELL(1) Git Manual GIT-SHELL(1)
NAME
git-shell - Restricted login shell for Git-only SSH access
SYNOPSIS
chsh -s $(command -v git-shell) <user>
git clone <user>@localhost:/path/to/repo.git
ssh <user>@localhost
DESCRIPTION
This is a login shell for SSH accounts to provide restricted Git access. It permits execution only of server-side Git commands implementing
the pull/push functionality, plus custom commands present in a subdirectory named git-shell-commands in the user's home directory.
COMMANDS
git shell accepts the following commands after the -c option:
git receive-pack <argument>, git upload-pack <argument>, git upload-archive <argument>
Call the corresponding server-side command to support the client's git push, git fetch, or git archive --remote request.
cvs server
Imitate a CVS server. See git-cvsserver(1).
If a ~/git-shell-commands directory is present, git shell will also handle other, custom commands by running "git-shell-commands/<command>
<arguments>" from the user's home directory.
INTERACTIVE USE
By default, the commands above can be executed only with the -c option; the shell is not interactive.
If a ~/git-shell-commands directory is present, git shell can also be run interactively (with no arguments). If a help command is present
in the git-shell-commands directory, it is run to provide the user with an overview of allowed actions. Then a "git> " prompt is presented
at which one can enter any of the commands from the git-shell-commands directory, or exit to close the connection.
Generally this mode is used as an administrative interface to allow users to list repositories they have access to, create, delete, or
rename repositories, or change repository descriptions and permissions.
If a no-interactive-login command exists, then it is run and the interactive shell is aborted.
EXAMPLE
To disable interactive logins, displaying a greeting instead:
+
$ chsh -s /usr/bin/git-shell
$ mkdir $HOME/git-shell-commands
$ cat >$HOME/git-shell-commands/no-interactive-login <<EOF
#!/bin/sh
printf '%s
' "Hi $USER! You've successfully authenticated, but I do not"
printf '%s
' "provide interactive shell access."
exit 128
EOF
$ chmod +x $HOME/git-shell-commands/no-interactive-login
