按文件中的列进行批处理排序 [英] Batch sort by column in file

问题描述

我想知道是否可以按列对文本文件进行排序.例如

I wonder if there is any posibility to sort a text file by columns. For example

我有 aux1.txt ，其中包含这样的行

I have aux1.txt with rows like this

Name SecondName Grade

在外壳中，我可以做到这一点

In shell i can do this

sort -r -k 3 aux1  

它按第3列(等级)对文件进行排序.

It sorts the file by the 3rd column(grade).

批量

sort /+3 < aux1.txt

在第三个字母后对文件进行排序.

sorts the file after the 3rd letter.

我阅读了有关批次的排序手册，但没有结果.

I read the sort manual for batch but no results.

推荐答案

您可以使用批处理文件编写自己的 sort-wrapper .

You could write your own sort-wrapper with a batch file.

您只需要将列重新排序到一个临时文件中，
排序并重新订购.(几乎是显而易见的)

You only need to reorder the columns into a temporary file,
sort it and order it back. (nearly obvious)

REM *** Get the desired colum and place it as first column in the temporary file
setlocal DisableDelayedExpansion
(
    for /F "tokens=1-3 delims= " %%A in (aux1.txt) DO (
        set "par1=%%A"
        set "par2=%%B"
        set "par3=%%C"
        setlocal EnableDelayedExpansion
        echo(!par2! !par1! !par2! !par3!
        endlocal
  )
) > aux1.txt.tmp

REM ** Now sort the first colum, but echo only the rest of the line
for /F "usebackq tokens=1,* delims= " %%A in (`sort /r aux1.txt.tmp`) DO (
    echo(%%B
)
