-# Background
 HPC systems are usually accessed via a Linux-based Command Line Interface (CLI).

 While there are many similarities to single-user Linux systems, HPC systems differ widely in the management of provided Software packages, and users must pay attention to the locality of data.
+## Learning Outcomes
-# Aim
+* Describe the command line interface and the bash shell as well es perform basic commands.
-  * To access and manipulate data.
+* Use and write basic shell scripts, e.g., to automate the execution of several commands.
-  * To execute programs in a cluster environment.
+* Sketch the organization of the typical file system tree.
-  * To use and write shell scripts e.g. to automatically execute several commands in a row that otherwise would have to be entered manually one by one and to automate simple tasks
+* Utilize essential tools to navigate and manage files.
-  * To select the right environment setting to build programs with the proper compiler, linker, and libraries versions or to run programs
+* Understand how to access a Cluster via SSH.
+* Understand terminal multiplexers and use them to run longer commands without keeping a connection alive.
+* Utilize tools to transfer data between a desktop/laptop system and a remote HPC system.
+* Utilize package management tools that provide access to a wide variety of software.
+* Demonstrate the usage of an editor to open a file in write mode and save the file and define why CLI based editors are useful in an HPC environment.
+* Utilize screen or tmux to preserve a session between logins and classify usecases for these three operations:
+    * Creation of a session.
+    * Detaching from the current session.
+    * Resuming a previous session.
+* Illustrate the use of CTRL-Z and CTRL-C in combination with the commands jobs and fg to send the signals SIGINT and SIGTSTP.
+* Experiment with the kill command and send the signals SIGKILL, SIGINT, SIGTSTP, also via the numbers instead of the names to a specific process id
