		+	Sometimes you may want to run long or complex commands. In this scenario, it can be useful to create an alias. This allows you to rename a command (or chain of commands) to an easier to type or remember command. An alias is a sort of shortcut, and it can be temporary or permanent.
		+
		+	For example, the command <code>vcgencmd measure_temp</code> on a Raspberry Pi will return the core temperature. However, this can be a tricky command to remember. So, let's create an alias.
		+	For a temporary alias, you can just enter in <code>alias temp="vcgencmd measure_temp"</code> on the command line. This will allow you to type "temp" and get the temperature. However, this alias will expire when you end your session (log out). To create a permanent alias, the following is required.

−	~~[[File~~:~~CMDOutput~~.~~png\|frame\|none\|An example output of running some commands in~~ the ~~shell]]~~	+	# Open .bash_profile: <code>nano ~/.bash_profile</code>
		+	# Add a line for the alias: <code>alias temp="vcgencmd measure_temp"</code>
		+	# Save and close the file
		+	# Reload .bash_profile: <code>source ~/.bash_profile</code>
