What happened in :doc:`/trainings/log/detail/FH-ECE-19/EC1/index` ...

Linux/UNIX
----------

* Linux Topics (:download:`Linux Basics (PDF)
  </trainings/material/pdf/010-linux-basics.pdf>`)

  * *Bausteine von Unix und Linux*

    5-7, 9-16

  * *Die Shell (Bash - "Bourne Again Shell")*

    36-45, 58-61, 63, 64
  
  * *Das Filesystem*
  
    Es ist wichtig, im Filesystem navigieren zu können. Die Basic Tools
    müssen sitzen (``cd``, ``ls``, ``pwd``, ``mkdir``, ``rm``, ``cp``,
    ``mv``, etc.). (Dazu muss man natürlich verstehen, was Files,
    Directories etc. sind.)
  
    Das *Permission*-Thema ist *extrem* wichtig, und man kann damit
    rechnen, dass zur Prüfung ein paar trockene Fragen zu dem Thema
    kommen.
  
    * Pfade: 67-71
    * Directories: 72-76
    * Symbolische Links: 77-79
    * Directory Listings (``ls``): 84-87
    * Kopieren und Verschieben (``cp`` und ``mv``): 88-91
    * Owner, Permissions: 92-97, 100
    * Die ``umask``: 98-99
    * Tools für Permissions: 100
    * Set-UID Bit: 101
    * Sticky Bit: 102

  * Das ``find`` Command: 105-109
  * Tools für Textfiles: 113ff.
  
    Das Kapitel wurde ansatzweise durchgegangen - jedes Tool. Wichtig
    ist, zu verstehen,
  
    * dass die Tools von *Standard Input* lesen, auf *Standard Output*
      schreiben (und auf *Standard Error* Fehler und Debug-Messages
      schreiben).
    * dass diese und andere Tools durch die Benutzung von *Standard
      Input* und *Standard Output* in der *Pipe*
  
  * IO Redirection und Pipes: 133ff.
  
    Dieses Kapitel wurde in einem mit den Tools durchgemacht,
    ansatzweise.
  
    Wichtig ist mir, dass die Wirkungsweise der Pipe verstanden wird,
    und dass man Tools mit ihrer Hilfe verknüpfen kann.

**Project on Github**

* Private repository on Github: https://github.com/jfasch/FH-ECE-19
* Create Github account, and send it to jf@faschingbauer.co.at
* Clone the repository

  .. code-block:: console

     $ cd directory-where-i-have-my-ec-work
     $ git clone https://github.com/jfasch/FH-ECE-19.git

* If you are getting tired of entering a password for each repo
  transaction, you can always `deploy a SSH public key to Github
  <https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh>`__,
  and then re-clone using the SSH access method:

  .. code-block:: console

     $ git clone git@github.com:jfasch/FH-ECE-19.git
