如何grep查找由于“”字符（破折号）而导致误报的精确字符串

Question

各位早上好,

我正在制作一个程序，将日志中的主机名与其他日志中的主机名进行比较。此程序的目的是确保网络的三个记录器（资产）（配置）（日志）正确地执行其工作，并记录网络上的所有主机名设备。我已经完成了脚本，但是现在我想使用unixsbash命令grep检查它们结果的有效性。我解析了所有三个日志文件，以确保没有遗漏任何内容，或者我的脚本意外地将主机名标记为拖欠，即使它正确地记录了日志

要显示为假阳性，搜索的主机名必须满足以下条件：

1. 拖欠主机名在日志中至少显示一次，并在日志中标记为拖欠
2. 主机名是唯一的，必须完全匹配，部分匹配不应触发结果

我一直在试验grep命令选项调用，但由于“-”字符，我无法解析出想要的结果。我不断得到显示部分匹配的结果，这不是我想要的

下面是我在python中运行的代码，使用子流程调用os bash命令：

    #First check the Asset accuracy
    for hostname in data['loggers']['asset']:
        #Call to an os bash command to check if the asset is listed
        if subprocess.run('show asset report csv | 'f'grep -Fm1 {hostname} ',
                              shell=True, check=False,
                              capture_output=False, ).returncode == 0:
            #If the asset shows up, mark as a false positive
            print(f'[ ! ] Hostname {hostname} is an Asset false positive')
            asset_false_positive.add(hostname)

    #Second check the config accuracy
    for hostname in data['loggers']['config']:
        #Call to an os bash command to see if the config is listed
        if subprocess.run(f'findconf {hostname}', shell=True, check=False,
                         capture_output=False).returncode == 0:
            print(f'[ ! ] Hostname {hostname} is a Config false positive')
            config_false_positive.add(hostname)

    #Third check the Log accuracy.
    for hostname in data['loggers']['log']:
        #Call to an os bash command to check if the log is listed
        if subprocess.run(f'grep -Fm1 {hostname} /var/log/{manufacturer[system]}',
                              shell=True, check=False).returncode == 0:
            print(f'[ ! ] False Positive Hostname: {hostname} in {manufacturer[system]}')

其中findconf（）具有bash代码：

findconf() { 
    find /home/net/hp/ /home/net/juniper/ /home/net/cisco/ /home/net/extreme/ -name "$1".config; 
}

我发现目前我的结果中存在真假阳性，如下所示：

但我的大多数结果都是假阳性（对不起，是双阴性），例如：

这是记录器原始输出（log）的一小部分：

我尝试在主机名前后添加空格，并将其设置为固定字符串。我没有得到任何结果。 我也试过白鹭，-w，以及所有可能的-Fwe组合

如何在不获得“-”字符部分匹配的情况下grep主机名

TL；博士 由于前面和后面的“-”字符，在我的grep命令中获得部分匹配。我怎样才能获得准确的结果
