有没有一种方法可以从日志中提取值并进一步使用bash来提取另一个值

Question

我试图从日志文件中读取一个值，然后根据该值搜索另一个文本。

以下是我的日志文件的外观。 我所拥有的只是customerId，订单ID是动态生成的

我想首先基于customerId捕获orderId并将其存储在变量中。

成功后，我要检查此订单ID的状态，该状态在下面约10行

最后，在控制台中打印它或写入文件都没关系

我是新手，我设法切片了10行，其中包含与CustomerID对应的OrderId，但无法切片OrderId并将其存储在变量中

$ cat orderlog_may_18 grep -A 15 "JE19802501"

预期结果正在打印

customerId : JE19802501
orderId : 72530548
status for 72530548 is success
customerId : JE19802501
orderId : 82530548
status for 82530548 is success

Answer 1

两行bash，使用sed。

ord=$(sed -n '/JE19802501/,/orderId/{/orderId/{s/[^0-9]//gp}}' orderlog_may18)
sed -n "/status for $ord/s/.*://p" orderlog_may18

$ ord存储JE198002501之后的orderId行中的数字，然后打印状态行的尾端。

您应该能够在bash脚本中进行所需的格式化。

Answer 2

$ awk -v trgt='JE19802501' '
    { gsub(/[",]/," "); $1=$1 }
    $1 == "customerId"                  { cust=$NF; print }
    ($1 == "orderId") && (cust == trgt) { ordr=$NF; print }
    $0 ~ ("status for " ordr " is")     { sub(/.*: /,""); print }
' file
customerId : JE19802501
orderId : 72530548
status for 72530548 is success
