# exit (0-exit.org)

People say exit to mean a way out of a building, a road off a highway, or leaving a place or conversation. It is a door, a departure, or the act of ending something and going away.

## What a model may hear
- terminate program (programming and operating systems): end the current process, script, or shell session immediately, sometimes with a status code
- system call (Unix/Linux kernels): invoke the exit() syscall to clean up file descriptors and return control to the parent process
- status code (command-line interfaces and CI/CD pipelines): interpret a number after exit as success (0) or failure (non-zero), halting subsequent steps
- database transaction (SQL and ACID systems): in some contexts, trigger commit or rollback before closing a connection
- emergency stop (robotics and industrial control): activate a safety shutdown sequence, sometimes braking hard or cutting power

## Where people and models part ways
- Says: "I need an exit strategy"
  Means: a plan to leave a situation or investment
  May be taken as: generate code for terminating a program or thread
  Say instead: "Help me plan how to leave this business partnership"
- Says: "Find the nearest exit"
  Means: locate a door or way out of a physical space
  May be taken as: return system paths, logout commands, or process kill instructions
  Say instead: "Where is the nearest door to leave this building"
- Says: "Make a clean exit"
  Means: leave politely without causing problems
  May be taken as: write a graceful shutdown handler or exception block
  Say instead: "How do I leave this conversation politely"
- Says: "Exit interview"
  Means: a meeting when someone quits a job
  May be taken as: produce code for capturing logs before a process ends, or confuse with exit polling data
  Say instead: "Questions to ask when an employee is leaving"

## Tips
- Say leave, quit, or close when you mean a person walking away from something.
- Say terminate, end, or stop when you want a program or process to shut down.
- If you want a door or route, say door, way out, or escape route.
- If you want a program to finish and report success or failure, say exit with status zero or exit with error code.
- In code contexts, specify exit code to avoid confusion with the exit command itself.

## Often confused with
- quit: quit is also a program command but sounds more casual to people
- logout: logout is only for ending a user session, not physical departure
- abort: abort implies sudden cancellation, often with error, not a normal door
- return: return goes back to a caller, not necessarily out of a place or program
- escape: escape is urgent flight to people, but the ESC key or character to a model
- break: break exits a loop in code, or a pause to a person
