meta@metabox:~ $ ls

meta@metabox:~ $ ls PROJECTS  
BLACKWIRE  CIPHERSTORM  DARKWATCH  GHOST_CIRCUIT  IRON_SENTINEL  NIGHTFALL_PROTOCOL  PHANTOM_SIGNAL  SHADOWGRID  SILENT_ECHO  ZERO_HORIZON

meta@metabox:~ $ ls PROJECTS/BLACKWIRE 
black_ops_codex_v214.docx  code  data  data_archive_619.zip  docs  flag.txt  incident_report.docx  secrets  secrets.yaml  src

meta@metabox:~ $ cat PROJECTS/BLACKWIRE/flag.txt
