Question

我需要一些关于是否可以这样做的建议。我有以下数据（这只是一行，会有这些行的块）在运行命令后出现，有没有办法可以使用grep和awk并解析每一行以一次性获取号码和所有者电子邮件，如下所示

Output:-

12345 mbarry@int.qualcomm.com

Input:-

                 The existing TL logging has been divided into three distinct modules:
                 TL_BA (14), TL_HO (13) and TL (existing module). Thus the log with
                 loglevel 5 in file chip_qct_tl_hostsupport.c can be viewed by issuing
                 the following command - iwpriv chip0 setchipdbg 13 5 1.

Answer 1

一次性使用grep：

$ grep -Po '(?<=(email|umber): )\S+' file
12345 
mbarry@int.qualcomm.com
3 
mbarry@int.qualcomm.com

使用xargs -n2将两者放在一行：

$ grep -Po '(?<=(email|umber): )\S+' file | xargs -n2
12345 mbarry@int.qualcomm.com
3 mbarry@int.qualcomm.com

$ grep -Po '(?<=(email|umber): )\S+' tfile | paste - -
12345   mbarry@int.qualcomm.com
3       mbarry@int.qualcomm.com

说明：

positive lookbehind '(?<=a)b'匹配b后跟a。在您的情况下，您希望匹配email:或number:后面的字符串，但正面背后必须是固定长度，因此我们必须删除n的数字。 \S+匹配一个或多个非空白字符。

(?<=   # Positive lookbehind 
(      # Group for alternation
email  # Literal string email
|      # Alternation (or)
umber  # Literal string umber
)      # Close 
:      # : Literal colon and single space 
)      # Close positive lookbehind 
\S+    # One or more non-whitespace character

使用awk：

$ awk -F: '/email|number/{print $2}' file | xargs -n2
12345 mbarry@int.qualcomm.com
3 mbarry@int.qualcomm.com

Answer 2

试试这些：

awk -F'[[:space:]:]+' '{a[$2]=$3} END{ print a["number"], a["email"] }' file
awk -F'[[:space:]:]+' '{a[$2]=$3} /email:/{ print a["number"], a["email"] }' file
awk -F'[[:space:]:]+' '{a[$2]=$3} /email:/{ print a["number"], a["email"]; exit }' file

如果这些都不是您正在寻找的，那么请提供您正在寻找的更多详细信息。

以上是上面的最后一个脚本如何使用发布的示例输入：

$ head -15 file
change I5e55796844350e543f8460c53ec6e755ebe663d4
  project: platform/vendor/company-proprietary/chip
  branch: master
  id: I5e55796844350e543f8460c53ec6e755ebe663d4
  number: 12345

                 TL_BA (14), TL_HO (13) and TL (existing module). Thus the log with

$ awk -F'[[:space:]:]+' '{a[$2]=$3} /email:/{ print a["number"], a["email"]; exit }' file
