Shell Scripting - How do we can create a sample ~/.dialogrc file

The dialog command allows you to display a variety of questions or messages from a shell script using dialog boxes. The ~/.dialogrc file is a run-time configuration file for dialog commands. Basically, it is the default configuration file. Also, the  ~/.dialogrc file allows us to customize various aspects of the dialog command. If you do not have the dialog command installed, run the following commands to install it:

sudo apt-get install dialog

Steps for creating a sample ~/.dialogrc file using bash scripting. 

Step 1: Create a bash file with extension .sh using the vim editor. Here other editors such as nano, and gedit can also be used at user convenience.

Step 2: Adding script into the bash script file i.e. bash.sh for creating the sample dialogrc file.

Bash Script for creating dialogrc file

#!/bin/bash

dialog --create-rc ~/.dialogrc

Output:

Step 3: Now, after successfully saving the bash script, we need to execute the script using the command given below 

sh bash.sh

Above command will run the bash script in the bash.sh file and as a result a sample ~/.dialogrc file is created.

We can view the content of the sample ~/.dialogrc file using the below command

vi ~/.dialogrc

Output : 

The content of our sample ~/.dialogrc file was as given below :
