Your home directory
The shared filesystem includes the home-directory area for the flight user which is created when your research environment is launched. Linux automatically places users in their home-directory when they login to a node. By default, the research environment will create your home-directory under the /users/ directory, named flight (/users/flight).
The Linux command line will accept the ~ (tilde) symbol as a substitute for the currently logged-in users’ home-directory. The environment variable $HOME is also set to this value by default. Hence, the following three commands are all equivalent when logged in as the user flight:
ls /users/flightls ~ls $HOME
The root user in Linux has special meaning as a privileged user, and does not have a shared home-directory across the research environment. The root account on all nodes has a home-directory in /root, which is separate for every node. For security reasons, users are not permitted to login to a node as the root user directly - please login as a standard user and use the sudo command to get privileged access.
