+I want an alias called **showip** that acutally does the same as typing ip addr |grep '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'
+\\
+\\
+You need to edit the .bash file for the logged in user who will use this alias. I am logged in as pi, so I will edit that bash file.\
+\\
+Navigate to root:
+\\
+     cd /root
+\\
+Show the list of files:
+\\
+     ls -al to show file list, you will see a list of files, including one called .bashrc\\
+\\
+Edit the .bashrc file by entering:
+\\
+      vi /root/.bashrc
+\\
+My default .bashrc file looks like this:
+\\
+        # .bashrc
+        # User specific aliases and functions
+        alias rm='rm -i'
+        alias cp='cp -i'
+        alias mv='mv -i'
+        # Source global definitions
+        if [ -f /etc/bashrc ]; then
+                . /etc/bashrc
+        fi
+\\
+Now add the new alias:
+\\
+        alias showip=" ip addr |grep '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'"
+\\
+save the file and exit:
+\\
+        :wq
+\\
+You have to restart the bash for any new aliases to work
+\\
+        . .bashrc
+\\
+If you want to see if the alias is now listed, from the command prompt just type:
+\\
+        alias
+\\
+You should now be able to type your new command at the command line and get an output:
+\\
+        showip
+            inet 127.0.0.1/8 scope host lo
+            inet 192.168.27.30/24 brd 192.168.27.255 scope global eth0
