如何在unix后台运行shell脚本?

how to run shell script in background in unix?

我的剧本

#!/bin/sh
while [ true ]
do
    ps -fu $USER>>/home/axway/trace.log 2>&1 
    sleep 10
done

在后台通过 nohup 命令在 promt 上运行上面的脚本(shellEx1.sh)

running above script (shellEx1.sh) in background by nohup command on promt

nohup ./shellEX1.sh &

有以下问题:

$ nohup ./shellEX1.sh &
[3] 19520
$ nohup: ignoring input and appending output to    `nohup.out'

推荐答案

它警告说脚本的输出将写入文件nohup.out".为了消除此警告，您可以尝试

Its warning to say like the output of the script will be written in file 'nohup.out'. In order to remove this warning, you can try

nohup ./shellEX1.sh >/tmp/output.txt &

或

nohup ./shellEX1.sh >/dev/null &
