An optional exit status is passed to the parent process; 0 conventionally indicates success.In scripts, exit immediately stops execution. In interactive shells, it closes the session. The exit status is available to the parent process via $? in shell scripts.Exit codes have conventional meanings: 0 for success, 1 for general errors, 2 for misuse, 126-127 for execution issues.
PARAMETERS
STATUS
Exit status code (0-255). 0 indicates success.
INSTALL

CAVEATS
Non-zero exits may trigger set -e termination. Status limited to 0-255. Subshells have separate exit. Traps may run before actual exit.
HISTORY
exit is a fundamental POSIX shell builtin, present since the original Bourne shell. Its semantics are consistent across all Unix shells.
