Question

我在空白行上打开/关闭echo时遇到问题。我已经尝试了多种方法，其中包括echo变量。

这是我当前使用的代码以及日志和当前输出，这是在我使用脚本来分析记录（某些记录为空白，而我希望保留为空白）之后的结果。

当前代码

for /f "skip=%skipTo% tokens=1,* delims=]" %%a In ('type %InputFile% ^| find /v /n ""') do (
    set ip=%%b
    set ip=!ip:!
    set test=!ip!
    echo !ip!
    echo(!test!

    if "!test!" == [] (
        !test! >> E:\EPM_Cloud\LoadFiles\BUD_PLN\Security\GROUPS_USERS_CURRENT_LIST.csv
    ) else (echo %%b >> E:\EPM_Cloud\LoadFiles\BUD_PLN\Security\GROUPS_USERS_CURRENT_LIST.csv)
)

当前输出（请注意，我需要保留当前具有“ ECHO已关闭”的3个空白行）

#group_children 
id,group_id,group_provider,user_id,user_provider 
BL_LEAD,,,TestUser_2,LDAP_Directory_Provider

当前日志-执行该代码后（如您所见，这就是为什么我在输出中得到空白行的证据？当没有空白行时，您会得到结果，但未在日志中显示

Answer 1

要消除当行为空（或空格，否则为空白）时ECHO IS OFF（或ON）消息，则只需使用ECHO(%%b而不是ECHO %%b。

传统上，人们使用ECHO.来消除空白行的问题。但是在某些晦涩的情况下，这可能会引起问题。

ECHO(始终有效。

Answer 2

if "!test!" == []将永远不会匹配。不要使用空格。

If "%string%"==""如果字符串为空，则执行某些操作。
