I beg to differ.
It's legitimate to assign a special script as a login shell when you want to
limit the user to just executing that command when logging in.
e.g. "/bin/nologin" or "/bin/halt".
The script should probably be pretty secure to prevent leaks (e.g. allow
injection of code via unquoted input).
I just created a user "testuser" on my desktop, assigned it a password, made
sure it has a home directory and a file named .hushlogin under it and set
its shell to the following script:
#!/bin/bash
echo Arguments: "$*"
And when I ssh to it I get:
# ssh testu...@localhost arg1
testu...@localhost's password:
Arguments: -c arg1
Seems to work fine. The OP will have to give more info to get help.
