[Question] Lots of path variables missing when using SSHClinet login remote

Hi, I have a question that. When I use SSHClient to connect to remote HPC, I find a lot of commands can not be found, such as 'qstat', module load. I inspect the ``$PATHand find some PATH variables which the administrator installs are missing. But those I write in.bashrc` stay. I wonder why and how to solve this problem.

Sorry for asking this silly question and hope you can help me. Thanks!
