REAP(1) General Commands Manual REAP(1)
NAME
reap – run process until all its spawned processes are dead
SYNOPSIS
reap [-vw] command line ...
DESCRIPTION
The reap utility executes the given command line and ensures all spawned
processes are dead before it exits.
By default, it will start slaying the spawned processes when the main
process exits. When the option -w is given, reap will instead wait for
the processes to terminate.
Upon receiving SIGINT or SIGTERM, reap will start slaying all children
immediately.
The options are as follows:
-w Wait for all spawned processes to finish.
-v Verbose mode, report what reap is doing.
EXIT STATUS
The reap utility exits with the exit status of the spawned command.
On fatal errors, exit codes 111 is returned.
ASSUMPTIONS
reap uses the PR_SET_CHILD_SUBREAPER feature of Linux. Slaying the
children only works when the kernel configuration CONFIG_PROC_CHILDREN is
enabled.
reap can only work reliably when it has permission to kill all spawned
processes and they respect SIGTERM.
