Linux is a widely used operating system, especially in server environments. Learning Linux can open up various career opportunities in system administration, DevOps, cloud computing, and cybersecurity. It is also a powerful tool for developers and provides a free and open-source platform for experimentation and learning.
While Linux does have GUI options, it is highly recommended to learn the command-line interface (CLI) as it provides more power and flexibility. The CLI is widely used in server environments and automation scripts. It also helps in troubleshooting and provides a deeper understanding of the underlying system.

Deciding which exam to go for among LFCS, RHCSA, and LPIC depends on your specific goals, career path, and preferences. Here are some factors to consider:
There are no formal prerequisites for the LPIC-101 certification. However, RHCSA certification typically requires basic knowledge and experience with Linux systems. LFCS certification does not have strict prerequisites but is designed for individuals with some experience in Linux system administration.
LFCS and RHCSA certifications are valid for three years, after which you can renew them to maintain your certification validity. LPIC-101 certification is also valid for five years, and you can renew it by passing higher-level LPIC exams or re-taking the LPIC-101 exam.
