6 hatimerun - Run command with a timeout.
7
9 hatimerun [-a] [-e exitcode] [-k sig] -t secs command [args]
10 hatimerun [-l|-h|-?]
11
13 Executes the given command with the given args with a timeout of secs
14 seconds. If the new process doesn't terminate before a timeout of secs
15 exceeds hatimerun sends the process a signal.
16 The command is run in its own process group, the termination signal is
18 sent to this process group.
19 hatimerun will always wait for the child to terminate, even if the
21 timeout occurred but the child didn't terminate on the signal.
22 The hatimerun process which waits for the child to exit ignores the
24 following signals: TERM, HUP, INT, PIPE, QUIT, USR1 and USR2.
25 -t secs
27 Specifies the time the command has to finish before a signal
28 will be sent. Multiple occurrences of -t are supported. Every
29 time a specified timeout happens a new signal is sent to the
30 child. See EXAMPLES section for more info.
31 -k sig Specifies the signal witch will be sent to the process group if
33 a timeout occurs. Multiple occurrences of -k are supported. In
34 case multiple -t arguments are specified every time a new time‐
35 out happens the next specified signal will be sent. if there are
36 less -k arguments then -t arguments specified the missing sig‐
37 nals are defaulted to SIGKILL. See EXAMPLES section for more
38 info.
39 Default: SIGKILL
41 -e exitcode
43 Changes the exitcode returned by hatimerun on timeout (if the
44 program ends normally or abnormally after the first signal was
45 sent) to exitcode Multiple occurrences of -e are supported in
46 connection with multiple occurrences of -t.
47 Default: 99
49 -a Starts hatimerun in the background. The hatimerun program exits
51 immediately. The return code of the executed command is lost.
52 -l Prints list of available symbolic signal names on this platform
54 and exits.
55 -h | -?
57 Prints a help screen and exits.
58
60 If the command terminates normally before the first timeout happend, On
61 success hatimerun returns the return value of the given command
62 After the first timeout happend hatimerun returns the value specified
64 by the respective -e option or 99 per default. hatimerun will always
65 wait for the program to terminate, even if the program terminates nor‐
66 mally after the first signal was sent, hatimerun will return the
67 respective error code as return value and the exit code of the command
68 is lost.
69
71 hatimerun -t 5 sleep 10
72 Will kill the sleep command after 5 seconds
73 hatimerun -k TERM -t 5 sleep 10
75 Will send the TERM signal after 5 seconds
76 hatimerun -k TERM -t 5 -e 100 -e 101 -t 1 sleep 10
78 Will send the TERM signal after 5 seconds, and (if the command
79 didn't finish till then) send the KILL signal one second later
80 (about 6 seconds after program start). Will return 100 if the pro‐
81 gram was terminated by the TERM signal or 101 if it was terminated
82 by the KILL signal.
83 hatimerun -k HUP -t 1 nohup sleep 1000
85 Will send a HUP signal after one second and then wait (potentially
86 forever) until the child terminates.
