如何保持 bash 脚本在后台运行

Question

I write a simple bash script:

while :
do
sleep 2;

//my code

done

Now I want this bash script always be running.

bash mybash.sh > /dev/null &

When I run above command my bash works fine. but when I close my terminal I think my bash is killed. because it doesn't work as my script make some files when it running.

Answer 1

在终端中运行脚本“bash script.sh”并按 ctrl+z 然后使用 'bg' 命令将脚本置于后台

Answer 2

#!/bin/bash

while true; do

// your code

sleep 5;

done;

write a bash script and put it that to cron and check once it will start comment the cron it will run in a background.

insted of sleep 5 you can use whatever second you want to put.

For checking your process use below commend to get the details ps -ef | grep script_file_name ps -ef | grep script_file_name

if you find more then one process is running leave one process and rest kill the process for script.

Hope so this will resolve your issue....!!!!
