  2. Team - Agenda • Practice-Labs: CompTIA  • RoadBlocks • Message

  3. Accessibility • Diversity and Inclusion • Technology for everyone • Fonts,Texts,Pixels,Sound

  4. Compress Data • Tools/Technology &Utilities • Gzip-highest compression command  gzip -9 hosts • Bzip- Create heavily compressed files • Xz- Better compression than gzip &bzip • Tar- Archiving utility

  5. Access Control Lists • A list of permissions attached to individual objects or groups • getfacl – retrieve ACLs of files and directories • setfacl – change ACLs
