+===== How to execute commands with back ticks =====
+
+If you need to include the output of a complex command in your script, you can write the statement inside back ticks.
+
+syntax:
+
+{{{
+var= ` commands `
+}}}
+
+Example: Suppose we want to get the output of a list of mountpoints with tmpfs in their name. We can craft a statement like this: df -h | grep tmpfs.
+
+{{{
+#!/bin/bash
+
+var=`df -h | grep tmpfs`
+echo $var
+}}}
+
+===== How to Automate Scripts by Scheduling via cron Jobs =====
+
+Cron is a job scheduling utility present in Unix like systems. Jobs can be scheduled to execute daily, weekly, monthly or in a specific time of the day. Automation in Linux heavily relies on cron jobs.
+
+Below is the syntax to schedule crons:
+
+{{{
+# Cron job example
+* * * * * sh /path/to/script.sh
+}}}
+
+Here, * represent represents minute(s) hour(s) day(s) month(s) weekday(s), respectively.
