格式化命令的输出

我目前正在尝试使用 Plink 在 Linux 服务器上运行一些命令来监视其上的一些内容，例如磁盘空间、内存、CPU 使用情况。
我有我想要使用的命令，但我想将输出格式化为更容易阅读的内容。
这是我在批处理文件中使用的命令。

 FOR /F "" %%G IN (C:\Users\username\Desktop\ip_list.txt) DO "C:\Program Files\PuTTY\plink.exe" -ssh -batch username@%%G -pw password "hostname; df | fgrep '/dev/'; free -h; top -bn2 | grep 'Cpu(s)';"

这是我得到的输出
在此输入图像描述
基本上，我想在各个命令输出之间添加一些行，以使其更易于阅读。如果不将输出写入文本文件，这可能吗？
谢谢

这可以通过添加来实现回声“”在命令中间需要空格的地方。

这里有一些例子。

  1. 在中间添加新行。

例子：

 df | fgrep '/dev/'; echo ""; free -h

输出

 tmpfs                                    16334344       55772  16278572   1% /dev/shm

              total        used        free      shared  buff/cache   available
Mem:            31G        4.0G         21G        346M        6.0G         26G
Swap:           15G        2.3M         15G
  1. 添加命令的详细信息。

受到推崇的

例子：

echo "==================" ; echo "This is output of df"; echo "==================" ;df | grep '/dev/shm' ; echo ""; echo "==================" ; echo "This is output of Free"; echo "==================";free -h

输出：

==================
This is output of df
==================
tmpfs                                    16334344       55772  16278572   1% /dev/shm

==================
This is output of Free
==================
              total        used        free      shared  buff/cache   available
Mem:            31G        4.0G         21G        359M        6.0G         26G
Swap:           15G        2.3M         15G

    Instead of displaying whole df command output i Wrote below script to find only if disk space crosses threshold (here i assuming threshold as 90%) and also included current memory usage percentage details

    Here is the code



      df -Ph| awk 'NR>1'| sed "s/%//g"| awk '($(NF-1) >90){print "Disk space utilized is" "  "$(NF-1)"%" " for partition" " "$NF}'|sed '1i Below are partition details of hosts where disk utilized crossed 90%\n'| sed '$s/.*/&\n=============================================================================/g';free  | awk '/Mem/{print $0}'| awk '{print $3/$2*100}'| sed '1i below are current memory usage percentage of host'



Sample output
Below are partition details of hosts where disk utilized crossed 90%

Disk space utilized is  100% for partition /snap/gnome-system-monitor/51
Disk space utilized is  100% for partition /snap/gtk-common-themes/1122
Disk space utilized is  100% for partition /snap/core/6531
Disk space utilized is  100% for partition /snap/gnome-calculator/260
Disk space utilized is  100% for partition /snap/gnome-logs/37
Disk space utilized is  100% for partition /snap/gtk-common-themes/818
=============================================================================
below are current memory usage percentage of host
39.2084
