 Unfortunately lacks the possibility to pass in variables.
 Which makes it unusable
+==== Read remote files ====
+To read remote file do use slurp
+<code>
+  - name: set facts
+    set_fact:
+      dest_timestamp: /tmp/progress/timestamp
+  - name: Slurp timestamp file
+    slurp:
+      src: "{{ dest_timestamp }}"
+    register: slurpfile
+  - name: set the timestamp fact
+    set_fact:
+      timestamp: "{{ slurpfile['content'] | b64decode }}"
+  - name: timestamp variable
+    debug: msg="{{ timestamp }}"
+</code>
+==== Execute a shell script, as a user with a valid environment ====
+Sometimes you face the issues, that the environment variables defined by some tool, installed for a special user - are not defined, when you execute the tool.
+To execute some installed software in a valid environment, \\
+with /home/bashrc \\
+with /etc/profile.d \\
+etc
+use the following approach.
+<code>
+      # unfortunately the environment defined by tool in /etc/profile.d - is not taken up by ansible. Explicitely requesting the interactive shell is necessary here
+      - name: processing step
+        shell:
+          sudo -iu ubuntu yourtool.sh   > /tmp/logs/yourtool.log 2>&1
+        args:
+          executable: /bin/bash
+       -i [command]
+                   The -i (simulate initial login) option runs the shell specified in the passwd(5) entry of the target user as a login shell.  This means that login-specific
+                   resource files such as .profile or .login will be read by the shell.  If a command is specified, it is passed to the shell for execution.  Otherwise, an
+                   interactive shell is executed.  sudo attempts to change to that user's home directory before running the shell.  It also initializes the environment, leaving
+                   DISPLAY and TERM unchanged, setting HOME, MAIL, SHELL, USER, LOGNAME, and PATH, as well as the contents of /etc/environment on Linux and AIX systems.  All other
+                   environment variables are removed.
+</code>

+UNfortunately the aproach with become_user - does not have the same result
