--json

portman --json prints the same data as JSON and exits. You can filter by port.

Architecture

From lsof to the kill key

lsof finds ports in LISTEN, sysinfo adds process details, and the result goes to the TUI or is printed as JSON.

01lsof finds TCP ports in the LISTEN state

02sysinfo adds CPU / memory, then scope, risk and type are assessed

03Shown in the TUI or printed as JSON

04Kill the process or copy the command from the table
