从 bash 中的行中提取两个子字符串，然后将它们连接起来

Question

此解决方案将成为脚本的一部分。

给定一个错误日志，我需要提取失败状态/失败原因和用户名，然后将它们连接起来，以便可以通过电子邮件发送输出。

我的输出应该是这样的：

Operation status: failed,Job Description not updated because this is not a matching Job Description ID.,username=FOO
Operation status: failed,Job Description not updated because this is not a matching Job Description ID.,username=BAR

错误日志文件中的每一行都与此非常相似：

"{ Operation status: failed,Job Description not updated because this is not a matching Job Description ID.,Sent Data:{lastAppraisalScore=0.0, country=null, jobTitle=LABORER..., username=FOO},...sendAcctActNotif=N}}"

文件中没有省略号；每行包含的内容远远超过显示的内容，但我只显示了重要的部分。

Answer 1

简单的sed 替换似乎更合适。

sed -n '/^"{ Operation status: failed,/!b
    s///;s/,Sent.*, username=/\t/;s/}.*//p' file

这会搜索第一个表达式；如果没有找到，我们绕过这条线。否则，我们将匹配的字符串替换为空，然后继续替换掉我们不想保留的其他字符串，最后打印剩下的内容。

Answer 2

使用this answer，您可以提取部分行（如果它总是看起来相同）。然后你可以逐行处理你的文件：

while read line; do
  status=`grep -oP '(?<=Operation status:).*?(?=Sent)' <<< "$line"`
  user=`grep -oP '(?<=username=).*?(?=})' <<< "$line" | head -n 1`
  echo "Operation status:" $status "username="$user
done < file.txt

我的示例文件.txt：

{ Operation status: failed1,Job Description not updated because this is not a matching Job Description ID.,Sent Data:{lastAppraisalScore=0.0, country=null, jobTitle=LABORER..., username=FOO1}, {username=BAR1}...sendAcctActNotif=N}}
{ Operation status: failed2,Job Description not updated because this is not a matching Job Description ID.,Sent Data:{lastAppraisalScore=0.0, country=null, jobTitle=LABORER..., username=FOO2}, {username=BAR2}...sendAcctActNotif=N}}
{ Operation status: failed3,Job Description not updated because this is not a matching Job Description ID.,Sent Data:{lastAppraisalScore=0.0, country=null, jobTitle=LABORER..., username=FOO3}, {username=BAR3}...sendAcctActNotif=N}}

我的输出：

Operation status: failed1,Job Description not updated because this is not a matching Job Description ID., username=FOO1
Operation status: failed2,Job Description not updated because this is not a matching Job Description ID., username=FOO2
Operation status: failed3,Job Description not updated because this is not a matching Job Description ID., username=FOO3
