Question

对于我工作的公司，我想在（实际上：2）日志文件中过滤掉某些消息。

这些消息仅供参考，在解决错误/故障时并不是特别有用。

经过长时间的讨论（我也发表了类似的问题，但对于Windows及其PS / BS（某些“牛粪”；）））

我认为AWK适合该工作，并且我编写了一个Shell脚本。但是，它没有运行（预期）。有人可以帮我“填补空白”吗？

#!/bin/bash

###To sort by what you WANT to see:
##e.g awk '/term to search/' dpkg.log

#if 
#    $var_show awk '/installed/' syslog/dpkg.log
#    then
#    printf('$var_show')
#fi







##Show what DONT want to see.
if
    #$var_notshow awk /'what not to display'/ syslog/dpkg.log
    $var_notshow awk /'Status Installed'/ dpkg.log
then
wc -1 > $var_notshow 
#echo number of merged messages (of the same content): xxx merged messages #< is the amount 
echo Messages of Status installed: $var_notshow were merged
fi 
###!!Show the amount of rules (when the same rule/logged event) that were merged
## E.g. (multiple lines which state: "Status Installed: xxxxxxxxxxxxx" ) and display it as: "Messages of Status Installed: xxxx were merged. Totalling: # of messages (of Status Installed)" were merged. 

### Finally, save it in a different file.
#Like: ?? how to do that?

因此，基本上，我有两种方法可以执行此操作：过滤所需的内容或不需要的内容。开始过滤掉我不想要的消息可能会更好/更干净。

是的，作为概念证明，我在测试机中使用了标准日志文件。我可以将其转换为公司的特定信息...

显示所有有趣的行：

grep interesting file

显示除无趣的行以外的所有内容：

grep -v "Status uninteresting" file

用awk计数：

awk '/uninteresting/{n++}END{print "uninteresting messages: "n}'

将命令输出重定向到新文件中

grep interesting file | grep -v uninteresting > newFile

或附加到newFile：

grep interesting file | grep -v uninteresting >> newFile

一次完成所有操作：

awk '/uninteresting/{u++;next}/interesting/{print}END{print "uninteresting lines: "u}'
this is interesting
uninteresting lines: 1

awk过滤出邮件/规则并显示合并邮件的数量
