 # bash-empty-daemon
-Template of empty daemon for Linux on pure bash
+Template of empty daemon for Linux on pure bash. Imagine, you need to make auto deploy from one server to another 5 or more servers. You may install special software for this with many dependencies and lot of else soft. But why? You can create SSH key for master server and attach this key to sother slave servers. Then you need only bash commands and thats all.
 
+```
+cd ~
+git clone git@github.com:vladimirok5959/bash-empty-daemon.git
+cd bash-empty-daemon
+chmod 0744 run.sh
+```
+
+```
+./run.sh
+./run.sh (once|start|stop|status)
+```
+
+```
+./run.sh once
+Loop. Every one second. Do something here...
+Loop. Every one second. Do something here...
+Loop. Every one second. Do something here...
+^C
+```
+
+```
+./run.sh status
+Daemon is not runned
+```
+
+```
+./run.sh start
+```
+
+```
+./run.sh status
+Daemon is runned with pid = 18504
+```
+
+```
+cat ./logs/all.log
+Loop. Every one second. Do something here...

+```
+
+```
+./run.sh stop
+Daemon stoped
+```
+
+Option **./run.sh once** will run script in non deamon mode. This is easy way to debug daemon body in file `loop.sh`, also you can simply shutdown daemon by pressing **Ctrl + C**.
+
+Option **./run.sh start** will run in daemon mode and you can safety close remote ssh connection.
+
+Option **./run.sh stop** will stop daemon.
+
+Option **./run.sh status** will show if daemon runned currently on not.
+
+## Where I can put my code?
+Look to the file `loop.sh`:
+```
+#!/bin/sh
+
+# Main daemon body
+echo "Loop. Every one second. Do something here..."
+```
+Contents of this file will be fired every second and each time.
