如何 Ping 多个 IP 地址并仅在 ping 失败或延迟大于 X 毫秒时保存到文件？ （Bash 或 PowerShell）
How to Ping multiple IP addresses AND only save to file if ping failed OR latency is greater than X milliseconds? (Bash or PowerShell)
我想编写一个简单的 PowerShell/Bash 脚本，该脚本将 运行 在一台高效 PC 的后台运行，每 1-5 秒检查一次每个选定成员是否可 ping 通。如果不是，则应将结果保存到带有时间戳和 IP 地址的 .txt 文件中。如果延迟大于例如，结果也应该保存到 .txt 文件中。 30 毫秒。
我已经有了
ping -t xxx.xxx.xxx.xxx |
ForEach-Object {"{0} - {1}" -f (Get-Date), $_} > C:\Users\xy\pingtest.txt
但这会将每个输出保存到 .txt 文件中，这对我帮助不大。
如何从这个解决方案到我想要的解决方案？

解释答案
创建 IP 地址数组
list=(192.168.1.{0..12})
您可以在文件中保存要 ping 的 iddress 列表，然后将其保存在该变量中list。这是一个 bash 序列表达式 {0..12} 填充一个范围内的数字，这种情况下，从 0 到 12。最终结果是 list=(192.168.1.0 192.168.1.1 192.168.1.2...)
这可以是字符串[域] 的列表，示例：并且工作正常
list=("amazon.com" "google.com" "target.com")
创建变量：
file=fileName_"$(date)".txt
$(date) 此命令将日期添加到文件[file_with_errors]
迭代数组list of ip's
for ip in "${list[@]}"; do
此行迭代名称为 list 的数组访问名称为 [@] 的所有项目，这是 bash.
的特殊语法
ping 每个 IP 2 次并将其保存到文件
ping -c 2 "$ip" >ipOutput.txt
-c 参数，ping 一个 ip 特定次数，在本例中为 2 次。 ping 后，将该输出保存到文件[ipOutput.txt] 而不是使用 > 的控制台，这会为每个新 IP 保存输出 ONCE。
检查 PING 的输出，如果存在错误，将其保存到文件
if [[ $? -ne 0 ]]; then
cat <file.txt >>"$file"
echo "error: $ip $(date) [saving to file]"
$? 打印最后一个命令 [PING] 的最后输出，因为它不等于 0，这意味着错误。 cat< ipOutput.txt 它显示 PING 的 OUTPUT 的内容，然后将该数据重定向到变量 $file[your_log_file] 和 >>，这意味着附加 [NO overwrite]。 echo 在终端中打印文本格式
如果没有报错继续ELSE语句
else
get_time=$(cat <ipOutput.txt | grep avg | awk -F '/' '{print }')
get_time 保存 ping ip 地址的平均时间，以毫秒为单位。
awk awk 是一个检查文本列的程序。
-F '/' 参数告诉 awk 使用哪个定界符，在本例中为 /。 {print } 抓取 数 毫秒。
抓取 grep 和 awk
的输出
- rtt min/avg/max/mdev = 1.637/1.693/1.749/0.056 ms
查看ping ip地址需要多长时间
if (($(echo "$get_time" '>='"$my_time" | bc -l))); then
我认为 (( )) 很奇怪，但为了比较，还是这样做。 $(commands) 用于在本例中编写命令和管道 echo, >=, |。运算符 >= 必须有 ' '。 | bc -l 用于比较 bash.
中的浮点数
This is just an IF STATEMENT, but bash needs special sintax for comparing two floats.
保存到文件，因为需要更多时间来 ping 所需时间
cat <ipOutput.txt >>"$file".txt
echo "$ip OK, but took MORE time: $get_time milliseconds [saving to file]"
else
echo "$ip : OK, less than $my_time milliseconds [$get_time]"
else 一切正常，未保存到文件，但在终端中显示正常状态
删除文件ipOutput.txt
rm ipOutput.txt
此文件用于保存每个 ip 使用 ping 命令的输出。此文件会覆盖每个新 ip 的数据，因此您可以使用 grep 和 awk.
更轻松地检索信息
