Examples of shell scripts to delete old Jenkins builds based on dates, size, and excluded filters.
Python enum package allows to utilise very powerful functionality in terms of managing constants and configuration entities.

In a set of examples below, we will demonstrate how to use enums in Python applications as well as the benefits of such usage.
In this post we will discuss in detail five different examples of how to use constants in Python applications:
This post presents examples of how to use macros to construct strings in definitions in C.
In this post, I would like to share an idea of a solution of an interesting task concerning manipulating multiple bash scripts running in background via prompts from another bash script.

This post shows an example of a bash script which creates a Docker container, copies a bash script to it, executes that script from the host, and saves its output on the host machine.
Examples of how to check if a Docker container with a given name exists and get its status in bash scripts.
