How to disable the message "Completion" when my team is killed by a timeout?

Question

We send bash: silently kill the background process of the function and the timeout of the command in bash without unnecessary delay , I wrote my own script to set the timeout for the command and also disable the error message.

But I still get a "Terminated" message when my process is killed. What is wrong with my code?

#!/bin/bash
silent_kill() {
    kill $1 2>/dev/null
    wait $1 2>/dev/null
}
timeout() {
    limit=$1 #timeout limit
    shift
    command=$* #command to run
    interval=1 #default interval between checks if the process is still alive
    delay=1 #default delay between SIGTERM and SIGKILL
    (
        ((t = limit))
        while ((t > 0)); do
            sleep $interval;
            #kill -0 $$ || exit 0
            ((t -= interval))
        done
        silent_kill $$
        #kill -s SIGTERM $$ && kill -0 $$ || exit 0 
        sleep $delay
        #kill -s SIGKILL $$
    ) &> /dev/null &
    exec $*
}
timeout 1 sleep 10

Answer 1

There is nothing wrong with the code that the “Terminated” message does not come from your script, but from the calling shell (the one you are running the script from).

, :

$ set +m
$ bash <your timeout script>

Answer 2

, bash 4 . , Terminated, . . :

$ sleep 100 &
[1] 15436
$ disown -r
$ kill -9 15436

help disown:

disown [-h] [-ar] [jobspec...]
.
JOBSPEC . JOBSPEC, .

• -a , JOBSPEC
• -h JOBSPEC, SIGHUP , SIGHUP
• -r
