如何将 slurm 命令的输出保存到文件中？

我已经安装了 slurm 命令来跟踪接口消耗的数据量apt install slurm

我的黄金是将其输出保存到文件中，我编写了这个脚本来让我做到这一点，但我没有得到预期的结果。

#!/bin/bash
echo "#####################################"
date "+%F %H:%M:%S :: snapshot on interface"
timeout 5s slurm -s -i eno1 >> /home/trackeNIC.log;

我添加这个作业来运行脚本

* * * * * bash /home/trackeNIC.sh >> /home/trackeNIC.log

我得到的结果是：

#####################################
2020-05-15 15:02:01 :: snapshot on interface
#####################################
2020-05-15 15:03:01 :: snapshot on interface
#####################################

我期望类似的东西：

#####################################
    2020-05-15 15:02:01 :: snapshot on interface

任何帮助，将不胜感激。

我想唯一可靠的方法是使用 screen 或 tmux 等程序。

因此，您可以让 slurm 在屏幕中运行，从屏幕会话中分离出来，然后运行

screen -X hardcopy /tmp/tmpfile
cat /tmp/tmpfile >> final_destionation.txt

在一个 cron 中

如果您需要捕获多个会话，您可以使用更多选项修改 screen，man screen 可以帮助您。

结果如下：

                     -= slurm 0.4.3 on catscrash-desktop =-

有很多空行，所以一些 grep 不会有什么坏处，但这是一个开始
