    CompTIA Linux+ Certification

    Often regarded as the first certification for Linux professionals, CompTIA Linux+ certification is an entry level certification designed for individuals with at least 6 months of practical Linux experience. This is a vendor-neutral certification.

    The Linux+ certification holder has the ability to explain:

    • managing of Linux systems from the command line
    • understanding of file permissions
    • software configuration
    • user administration
    • security

    A more specific list of topics covered by the exam can be seen below, listed under the sections of the exam.
