listener.log分时段统计连接数
有的时候需要从listener.log分析连接数情况：截取特定时间段的日志
sed -n '/开始时间/,/结束时间/p' listener.log同一天按小时统计连接数

你可以使用以下的shell命令来统计listener.log中不同主机的连接次数：
grep -oE "\b({1,3}\.){3}{1,3}\b" listener.log | sort | uniq -c
这行命令会首先使用grep命令匹配listener.log中的IP地址，并使用sort和uniq命令来对IP地址进行排序和去重，并且使用uniq -c来统计每个IP地址出现的次数
这个命令将会：
使用grep命令和正则表达式\b({1,3}\.){3}{1,3}\b在listener.log文件中匹配并提取IP地址。
\b用于匹配单词边界，确保我们只获取完整的IP地址。
({1,3}\.){3}用于匹配3个由数字和点号组成的分组，表示IP地址的前三部分。
{1,3}用于匹配最后一个IP地址部分，即最后一个数字。
使用sort命令对提取的IP地址进行排序。
使用uniq -c命令统计每个唯一IP地址出现的次数，并在每行前面显示计数。
请确保将listener.log替换为实际的监听器日志文件路径。运行命令后，你将会得到一个包含IP地址和计数的列表。
如果你想要从 listener.log 文件中提取 program，并统计它们的数量，可以使用以下命令：
grep -oE "PROGRAM=[^)]+" listener.log | sort | uniq -c
该命令会执行以下操作：
使用 grep 命令和正则表达式 PROGRAM=[^)]+ 从 listener.log 文件中匹配并提取 program。
PROGRAM= 匹配 program 字符串。
[^)]+ 匹配不包含 ) 的任意字符，确保我们只提取一个完整的 program。
使用 sort 命令对提取的 program 进行排序。
使用 uniq -c 命令统计每个唯一的 program 出现的次数，并在每行前面显示计数。
请确保将 listener.log 替换为实际的监听器日志文件路径。执行该命令后，你将获得一个包含 program 和计数的列表。
如果你想要从 listener.log 文件中提取 user，并统计它们的数量，可以使用以下命令：
grep -oE "USER=[^)]+" listener.log | sort | uniq -c
该命令会执行以下操作：
使用 grep 命令和正则表达式 USER=[^)]+ 从 listener.log 文件中匹配并提取 user。
USER= 匹配 user 字符串。
[^)]+ 匹配不包含 ) 的任意字符，确保我们只提取一个完整的 user。
使用 sort 命令对提取的 user 进行排序。
使用 uniq -c 命令统计每个唯一的 user 出现的次数，并在每行前面显示计数。
请确保将 listener.log 替换为实际的监听器日志文件路径。执行该命令后，你将获得一个包含 user 和计数的列表
要统计特定时间段内不同主机的连接次数，你可以使用以下的shell命令：
grep '开始时间' listener.log -A $(($(grep -n '结束时间' listener.log | cut -d: -f1) - $(grep -n '开始时间' listener.log | cut -d: -f1))) | grep -oE "\b({1,3}\.){3}{1,3}\b" | sort | uniq -c
请将"开始时间"和"结束时间"替换为你想要统计的时间段。这个命令会首先使用第一个grep命令找到开始时间行所在的位置，并通过-A参数来匹配从开始时间到结束时间之间的行。然后使用第二个grep命令匹配IP地址，并使用sort和uniq命令来统计每个IP地址出现的次数。
请确保时间格式与listener.log中的日期和时间格式匹配，否则可能无法正确匹配到时间段内的内容。 #!/bin/sh
