Entry Level Credential: Linux Essentials

This expansion of open source in enterprise is redefining traditional Information and Communication Technology (ICT) job roles to require more Linux skills. Whether you’re starting your career in Open Source, or looking for advancement, independently verifying your skill set can help you stand out to hiring managers or your management team. The Linux Essentials Professional Development Certificate (PDC) is a great way to show employers that you have the foundational skills required for your next job or promotion. It also serves as an ideal stepping-stone to the more advanced LPIC Professional Certification track for Linux Systems Administrators.

scp(1): secure copy

File names may contain a user and host specification to indicate that the file is to be copied to/from that host.
