grep: A Command That Helped Me Pass a Technical Interview (and How I Still Use It Years Later)
In this video, I explain one of the most useful command-line tools every programmer should know: grep. It helped me solve a real technical interview task years ago, and I still use it in my daily workflow today.
I was given a task where I had to search through a large codebase without using an IDE or running the code. This is where grep helped me quickly find the relevant files and complete the task efficiently. The video also covers a few practical ways I use grep in real workflows, along with simple examples and related command-line techniques you can apply immediately. This video is perfect for programming learners, computer science students, and anyone interested in command line tools, Linux, and real world software engineering workflows.
You will learn:
What grep is and why developers use it
How to search files in a large codebase quickly
Real world examples of grep in action
Why command line tools are still essential in modern development
Commands used in this video:
grep -rl "text"
grep -r "text" .
grep -rl "exampleFunction" . --include="*.ts"
In real world software engineering, especially in DevOps, backend development, and server environments, you often do not have access to an IDE. That is why command line tools like grep are extremely powerful and widely used. If you are learning programming or want to improve your developer workflow, this is a great tool to start with.
Thanks for watching.
