timeout(1) The Netatalk Project timeout(1)NAME
timeout - Send a signal to a program after a certain time
SYNTAX
timeout [-s signal] seconds program [args]
DESCRIPTION
timeout executes a program (with arguments args) and sends a signal to it after a certain amount of seconds.
OPTIONS -s signal
Signal to send to the spawned process. This can be a numerical or symbolic ID. This defaults to TERM.
EXAMPLES
timeout 10 pap foo.ps
Execute "pap foo.ps" and send a SIGTERM if pap doesn't return after 10 seconds.
timeout -s HUP 60 sh
Spawn a shell and send a hangup signal after one minute.
timeout -s 9 10 evilprog
Execute a program and KILL it if it doesn't quit after 10 seconds.

hatimerun - run child program under a timeout
SYNOPSIS
/usr/cluster/bin/hatimerun -t timeOutSecs [-av] [-e exitcode]
prog args
/usr/cluster/bin/hatimerun -t timeOutSecs [-v] [-e exitcode]
[-k signalname] prog args
DESCRIPTION
The hatimerun utility provides a convenient facility for timing out the execution of another child, program. It is useful when programming
in scripting languages, such as the Bourne shell. See sh(1).
The hatimerun utility runs the program prog with arguments args as a child subprocess under a timeout, and as its own process group. The
timeout is specified in seconds, by the -t timeOutSecs option. If the timeout expires, then hatimerun kills the child subprocess's process
group with a SIGKILL signal, and then exits with exit code 99.
You can run this command in the global zone or in a non-global zone. The command affects only the global or non-global zone in which you
issue the command.
OPTIONS
The following options are supported:
-a Changes the meaning of hatimerun radically: instead of killing the child when the timeout expires, the hatimerun utility sim-
ply exits, with exit code 99, leaving the child to run asynchronously.
It is illegal to supply both the -a option and the -k option.
-e Changes the exit code for the timeout case to some other value than 99.
-k Specifies what signal is used to kill the child process group. The possible signal names are the same as those recognized by
the kill(1) command. In particular, the signal name should be one of the symbolic names defined in the <signal.h> descrip-
tion. The signal name is recognized in a case-independent fashion, without the SIG prefix. It is also legal to supply a
numeric argument to the -k option, in which case that signal number is used.
It is illegal to supply both the -a option and the -k option.
-t Specifies the timeout period, in seconds.
-v Verbose output, on stderr.
EXIT STATUS
If the timeout occurs, then hatimerun exits with exit code 99 (which can be overridden to some other value using the -e option).
If the timeout does not occur but some other error is detected by the hatimerun utility (as opposed to the error being detected by the
child program), then hatimerunhatimerun exits with exit code 98.
Otherwise, hatimerun exits with the child's exit status.
The hatimerun utility catches the signal SIGTERM. It responds to the signal by killing the child as if a timeout had occurred, and then
exiting with exit code 98.
