Macbook 系统分析器已格式化

我想格式化从 macbook 终端命令生成的输出system_profiler，并将行值转置到同一应用程序下的列。

这是该文件的片段：

火狐浏览器：

  Version: 32.0.3
  Obtained from: Identified Developer
  Last Modified: 28/09/2014 18:23
  Kind: Intel
  64-Bit (Intel): Yes
  Signed by: Developer ID Application: Mozilla Corporation, Developer ID Certification
  Location: /Applications/Firefox.app
  Get Info String: Firefox 32.0.3

Calendar:

  Version: 7.0
  Obtained from: Apple
  Last Modified: 18/03/2014 06:58
  Kind: Intel
  64-Bit (Intel): Yes
  Location: /Applications/Calendar.app

...并希望输出如下图所示：

笔记：

  1. 并非每个申请都会填写所有栏目
  2. 此类信息最多有 8 个（请参阅 Firefox 应用程序下的完整集）
  3. 每个应用程序信息组之间的前导填充空格和换行符

awk -F: ' # set fields separator to :
$1!="" && $2==""{i++;NAME[i]=$1} # if 1st field without second it is app.name
$2!=""{HEAD[$1]=1;DATA[NAME[i],$1]=$2 $3} # put variables name into array
#+ put variables into 2-dimention array app.name,var.name  
END{
printf("%s:","Application"); # first column in header
for (n in HEAD) printf("%s:",n); # print all var.name as header separated by :
print ""; # finish line by newline
for(i in NAME){ # for each app.name
  printf("%s:",NAME[i]); # print app.name
  for (n in HEAD) printf("%s:", DATA[NAME[i],n]); # print each variables corresponding to app.name
  print ""; # finish line by newline
  }
}' data.file | sed -E 's/:\s*/:/g' | column -s: -tn

sed 删除之后的所有空格:

column设置文本列的格式
