如何將 slurm 命令的輸出保存到文件中？

我已經安裝了 slurm 命令來跟踪介面消耗的數據量apt install slurm

我的黃金是將其輸出保存到一個文件中，我編寫了這個腳本讓我這樣做，但我沒有得到預期的結果。

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

我添加了這個作業來執行腳本

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

我得到的結果是：

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

我期待類似的東西：

任何幫助，將不勝感激。

我想唯一確定的方法是使用 screen 或 tmux 之類的程序。

所以，你可以讓你的 slurm 在螢幕上執行，從螢幕會話中分離，然後執行

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

在一個 cron

如果您需要擷取多個會話，您可以使用更多選項修改螢幕，man screen 可以幫助您。

結果如下所示：

有很多空行，所以一些 grepping 不會受到傷害，但這是一個開始
