shell脚本将选定文本写入单行

您好，我有一个日志文件trace.log，它打印时间戳、线程名称、事务方法和事务ID，如下所示

2014-01-23 15:50:41,724 [catalina-exec-35] INFO  TRANSACTION getConnection REQUEST, ID=1308::
2014-01-23 15:50:41,725 [catalina-exec-33] INFO  TRANSACTION getConnection REQUEST, ID=1304::
2014-01-23 15:50:41,727 [catalina-exec-10] INFO  TRANSACTION getConnection REQUEST, ID=1298::

我想grep并将getConnection请求的时间戳和getConnection DONE（针对特定ID）的时间戳打印到一个文件中

我已经编写了一个shell脚本，它将时间戳打印成多行，如下所示。 这是我的shell脚本

 for i in {1..800}
 do
      echo "Welcome $i times"
      echo "ID=$i, getConnection " >> time.log
      grep ID=$i: trace.log | grep getConnection | cut -d'[' -s -f1 >> time.log
 echo "      " >> time.log
 done

输出如下所示

   ID=791, getConnection
   2014-01-23 15:50:16,703
   2014-01-23 15:50:16,706

   ID=792, getConnection
   2014-01-23 15:50:16,704
   2014-01-23 15:50:16,704

   ID=793, getConnection
   2014-01-23 15:50:16,704
   2014-01-23 15:50:16,709

   ID=794, getConnection
   2014-01-23 15:50:16,708
   2014-01-23 15:50:16,712

ID=792, getConnection 2014-01-23 15:50:16,703 2014-01-23 15:50:16,706

ID=792, getConnection 2014-01-23 15:50:16,704 2014-01-23 15:50:16,704

ID=793, getConnection 2014-01-23 15:50:16,704 2014-01-23 15:50:16,709

ID=794, getConnection 2014-01-23 15:50:16,708 2014-01-23 15:50:16,712

我怎么能做到？请帮忙

我需要如下所示的输出

   ID=791, getConnection
   2014-01-23 15:50:16,703
   2014-01-23 15:50:16,706

   ID=792, getConnection
   2014-01-23 15:50:16,704
   2014-01-23 15:50:16,704

   ID=793, getConnection
   2014-01-23 15:50:16,704
   2014-01-23 15:50:16,709

   ID=794, getConnection
   2014-01-23 15:50:16,708
   2014-01-23 15:50:16,712

ID=792, getConnection 2014-01-23 15:50:16,703 2014-01-23 15:50:16,706

ID=792, getConnection 2014-01-23 15:50:16,704 2014-01-23 15:50:16,704

ID=793, getConnection 2014-01-23 15:50:16,704 2014-01-23 15:50:16,709

ID=794, getConnection 2014-01-23 15:50:16,708 2014-01-23 15:50:16,712

管道连接到

tr

以删除换行符，如下所示：

grep ID=$i: trace.log | grep getConnection | cut -d'[' -s -f1 | tr -d '\n'

---

使用

awk

可以通过更改以下命令来保存某些命令：

grep ID=$i: trace.log | grep getConnection | cut -d'[' -s -f1

致：

为什么不让

awk

doall（使用您的数据）：

---

一些更改了版本并添加了

sort

awk -F" \\\[|=" '{split($3,i,":")} g {/DONE/?d[i[1]]=$1:r[i[1]]=$1} END {for (j in r) print "ID="j,g,r[j]","d[j]}' g="getConnection" file | sort -k1
ID=1298 getConnection 2014-01-23 15:50:41,727,2014-01-23 15:50:41,733
ID=1304 getConnection 2014-01-23 15:50:41,725,
ID=1307 getConnection 2014-01-23 15:50:41,727,
ID=1308 getConnection 2014-01-23 15:50:41,724,2014-01-23 15:50:41,733
ID=1309 getConnection 2014-01-23 15:50:41,738,
ID=1310 getConnection 2014-01-23 15:50:41,737,
ID=1311 getConnection 2014-01-23 15:50:41,738,2014-01-23 15:50:41,744
ID=1313 getConnection 2014-01-23 15:50:41,734,2014-01-23 15:50:41,734
ID=1315 getConnection 2014-01-23 15:50:41,743,
ID=1318 getConnection 2014-01-23 15:50:41,747,

另一个需要修改的是说

echo-n“ID=$i，getConnection”>>time.log

。如何在两个字段之间引入空格，2014-01-23 15:50:16和2014-01-23 15:50:16706您应该已经获得了一个空格，因为

[

。不需要通过循环所有数字来测试它是否存在。您可以将所有数字存储在数组中并从中排序。
