+""" Execute command in shell and print result
+
+Few command examples:
+    'ping 1.1.1.1 -c 1 | grep -Po "(?<=time=)\d+(\.\d+)? ms"'
+    'echo "BTC=$(curl -s rate.sx/1BTC | grep -Po \"^\d+\")USD"'
+    'curl -s https://wttr.in/London?format=%l+%t+%h+%w'
+    'pip3 freeze | wc -l'
+    'any_custom_script.sh | grep arguments'
+
+Parameters:
+    * shell.command:  Command to execute
+                      Use single parentheses if evaluating anything inside
+                      For example shell.command='echo $(date +"%H:%M:%S")'
+                      But NOT shell.command="echo $(date +'%H:%M:%S')"
+                      Second one will be evaluated only once at startup
+    * shell.interval: Update interval in minutes
+                      (defaults to 1s == every bumblebee-status update)
+    * shell.async:    Run update in async mode. Won't run next thread if
+                      previous one didn't finished yet. Useful for long
+                      running scripts to avoid bumblebee-status freezes
+                      (defaults to False)
