多列日志文件的后处理

我正在对多列日志填充进行后处理，格式如下：

请注意，第 1 列和第 2 列以逗号 (,) 分隔，其余列以逗号空格 (, ) 分隔。从这个日志文件中我需要：

  1. 将第一列（长unix格式路径/Users/gleb/Desktop/scripts/...）中的所有数据替换为相应的行号（仅第N行）；
  2. 删除第 6-9 列（最后四列）；

最终生成的日志应包含相同数量的行，但仅从第 1 列（带替换！）到第 5 列（带 的最后一列0,）。

我能够完成的是使用 sed 在第一列中进行替换，但这只是切断了路径，但没有在那里引入相应的行号：

sed -i '' -e 's|\/Users/gleb/Desktop/scripts/analys_clusters/sub_folders_to_analyse/*.*/||' log.txt

答案1

gawk -F'^[^,]*,|, ' '{ print NR, $2, $3, $4, $5; }' OFS=', ' infile

首先跳过氮行，添加NR> N到awk，所以首先氮行将被跳过；要跳过第一行，你可以这样做：

gawk -F'^[^,]*,|, ' 'NR> 1{ print NR, $2, $3, $4, $5; }' OFS=', ' infile

随后您需要修改NR为NR-1，因此将从1不是2，或者将其替换为另一个临时变量，例如：

gawk -F'^[^,]*,|, ' 'NR> 1{ print ++lineNumber, $2, $3, $4, $5; }' OFS=', ' infile

^[^,]*,匹配从行首到第一个逗号字符；
, 匹配逗号空格字符。

上面这些我们定义为字段分隔符（用 分隔|），并基于此我们打印相应的字段；NR在awk代表当前行号。

另一种选择是使用cutand nl：

<infile cut -d',' -f2-6 |nl -w1 -s', '

cut命令剪切字段 2~6 并nl用逗号分隔的行编号,；-w将 1 列宽度设置为数字。
