Windows批处理文件将空白字段更改为值

Question

我正在编写一个Windows脚本来读取包含9列数据的txt文件,我希望将此数据写入csv文件以加载到数据库中.

我发现一列有时是空白的,所以我想输入代码'rdp',另一列主要是数字,但是由于某些值是'.' (大概指示值小于1.我想将这些值更改为'0'

我的代码

  for /F %%b in (c:\ts_users\newfiles_list.txt) do (
      for /F "tokens=1,2,3,4,5,6,7,8,9" %%i in (%%b) do (
        echo %%i,%%j,%%k,%%l,%%m,!idle!,%%o %%p,%%q >>%%~nb.csv
      )
    )

这设法读入txt文件,然后将其写为csv.列k有时是空的,列n有时会有'.'

我尝试了各种变体

    set var=rdp
    if %%k="" then set !k:=!var!

这不起作用,所以我有点难过(谷歌搜索互联网几天后)
