20 Basic Linux Commands for Data Science in 2024

Introduction

Linux, the operating system favored by data science professionals, offers flexibility, power, and open-source tools. As a data science beginner, mastering the Linux command line is a key step towards empowering yourself in data manipulation, analysis, and modeling. This article will provide you with 20 basic Linux commands essential for your journey in data science.

Why You Must Know Linux Commands for Data Science?

As a data science professional, having a strong command of Linux commands is essential for several reasons:

1. Data Processing and Analysis: As already noted, data science is characterized by working with huge and cumbersome data sets that are processed for a long time on personal computers or conventional operating systems. Linux has powerful command-line tools and utilities that can efficiently handle and manipulate large amounts of data. You can easily perform complex data filtering and transformation using such common tools as grep, sort, awk, sed.
2. Reproducibility and Automation: Reproducibility, as a feature of data science, is another aspect of work. A user can combine numerous Linux commands into scripts, making it convenient to apply data processing pipelines and simultaneously thoroughly document and record this process, guaranteeing identical results each time one runs the script. Therefore, indubitably, this means preparing to share work with others in diverse ways.
3. Remote Computing and Cloud Resources: Many data science projects require access to powerful computer resources, such as high-performance clusters or cloud-based platforms. Linux is the dominant operating system in these environments, and knowing the ins and outs of Linux commands is a critical skill for using these resources and managing remote computations effectively.
4. Package Management and Software Installation: Linux distributions often come with package managers like apt, yum, or dnf, which simplifies installing, updating, and managing software packages. This is particularly important in data science, where you frequently need to install and configure various libraries, frameworks, and tools for data manipulation, visualization, and modeling.
5. Version Control and Collaboration: Git is an indispensable version control system for recording changes to computer code, data, and documents and enabling multiple team members to collaborate. Although Git works on different operating systems, it works smoothly with Linux as most Git commands are built around Linux’s file system and text-based command-line interface.
6. Interoperability and Portability: Since Linux is a cross-platform operating system, scripts and commands written on one Linux system can generally be used on other Linux distributions or Unix-like systems with few or no changes. This portability is incredibly useful in data science, as you may work with various computing environments or develop your solutions to run on multiple platforms.
7. Efficient Use of System Resources: Linux is popular due to its effective system resource utilization, and thus, it is a good platform to run data science tasks that require intensive computations. Knowing the commands that facilitate activity monitoring and system resource management is important. This information is useful for optimal system performance and preventing bottlenecks.

In conclusion, it is feasible to do most, if not all, data science work on other operating systems, like Windows or macOS. However, the Linux command line is a robust, versatile, and prevalent environment for data science. Learning and understanding Linux commands will help you own the tools and skills needed to work better, cooperate successfully, and generate high-quality outcomes that are easily replicable in data science.
