我用nohup命令有问题。
当我运行我的工作时，我有很多数据。输出nohup。Out变得太大，我的进程变慢了。我如何运行这个命令而不得到noup .out?

sudo bash -c "nohup /opt/viptel/viptel_bin/log.sh $* &> /dev/null" &
重定向sudo的输出会导致sudo重新询问密码，因此需要一种笨拙的机制来执行这种变体。

你可能需要使用分离程序。您可以像nohup一样使用它，但是它不会产生输出日志，除非您要求它这样做。下面是手册页:
NAME
detach - run a command after detaching from the terminal
SYNOPSIS
detach [options] [--] command [args]
Forks a new process, detaches is from the terminal, and executes com‐
mand with the specified arguments.
OPTIONS
detach recognizes a couple of options, which are discussed below. The
special option -- is used to signal that the rest of the arguments are
the command and args to be passed to it.

Connect file to the standard error of the command.
-f Run in the foreground (do not fork).
-i file
Connect file to the standard input of the command.
-o file
Connect file to the standard output of the command.
-p file
Write the pid of the detached process to file.

nohup some_command > /dev/null 2>&1&
这就是你所需要做的!
您可以执行如下命令。
nohup <your command> & > <outputfile> 2>&1 &
如。 我在脚本里面有一个nohup命令
./Runjob.sh > sparkConcuurent.out 2>&1
sudo bash -c "nohup /opt/viptel/viptel_bin/log.sh $* &> /dev/null" &
重定向sudo的输出会导致sudo重新询问密码，因此需要一种笨拙的机制来执行这种变体。
你试过重定向所有三个I/O流吗:
nohup ./yourprogram > foo.out 2> foo.err < /dev/null &
