Question

我有一个传入的文件，如（ in.txt ），它是一个制表符分隔文件，其中包含否标题行。我希望每行重复两次并进行替换（基于规则）。我是* nux的新手，我完全不知道哪些工具可以帮助我做到这一点。

传入文件（ in.txt 。按标签分隔（\ t））

A       B                C               D               E                      F       G       H 
1   855211046    2/3/2015    $170.00     4154245328852953   328573  1809    CC786875287728777
2   855211046    3/3/2015    $100.10     5524415875875844   822409  1809    CC150330106885244
3   855211046   30/3/2015    $105.00     4875875852875211   445092  1809    CC456387885245062
etc.

预期结果（ Outcome.txt ）

规则

*1st record*
^2.{9}.{7}.{16}([Column B's data, 0 fill right till the position 12]).{8}([Column C's data but reformat to YYMMDD format])
^5([Column B's data, 0 fill right till the position 18]).{7}([Column E's data, SPACE fill right till the position 19]).{60}([Column C's data but reformat to YYMMDD format])([Column F's data]).{10}\s{1}([Column D's data but remove $ sign and then multiplied by 100])
^5([Column B's data, 0 fill right till the position 18]).{7}([Column E's data, SPACE fill right till the position 19]).{60}([Column C's data but reformat to YYMMDD format])([Column F's data]).{122}([Column D's data but remove $ sign and then multiplied by 100])

*2nd record*
same as 1st

*3rd record*
same as 1st

非常感谢。

Answer 1

这并不难，但需要注意和打字：

awk '
/./{
split($3,T,"/")
$3=sprintf("%d%02d%02d",T[3]-2000,T[2],T[1])
sub("\\$","",$4);$4*=100

printf "^2.{9}.{7}.{16}(%d%0."12-length($2)"d).{8}(%d)\n",$2,0,$3
printf "^5(%d%0."18-length($2)"d).{7}(%-19d).{60}(%d)(%d).{10}\\s{1}(%012d)\n",$2,0,$5,$3,$6,$4
...
}' in.txt >Outcome.txt

我确信根据上面的示例，您可以轻松地为第3行输出添加printf。
