Question

我有一些批量编写的代码。该脚本应该使用数据库的SQLDump，然后使用7zip将其压缩，然后将压缩文件存档到历史文件夹中。下面是我的整个脚本，提供了上下文，并了解了整体情况，但我的问题是第二个FOR循环，这就是这里：

FOR /F "usebackq" %%A IN ('%encryptedFile%') DO set encryptedFileSize=%%~zA

    :: Checks the zipped back up is greater than 0 (No failure on zipping)
    IF %encryptedFileSize% GTR %maxbytesize% (
        %date:~6,4%%date:~3,2%%date:~0,2%-%time:~0,2%-%time:~3,2% %FileName% Encrypted Successfully >> Backup.txt
        ::Move the zip file
        MOVE %FileName%.7z BackupHistory
        ::DEL %FileName% - do i need this?

        ::Deletes error log if the backup is successful; Error log will still be there if backup failed
        DEL %errorLog%
    ) ELSE (
        ::Logs that zip & encryption failed
        @ECHO %date:~6,4%%date:~3,2%%date:~0,2%-%time:~0,2%-%time:~3,2% %FileName% Encryption Failed 2> ZIPFailure.txt
    )

整个脚本将运行OK（例如，使用转储，压缩它），但是当它到达下一位时，检查压缩文件大于50KB，然后移动文件并删除原始备份就失败了。它在屏幕上返回的错误是（从CMD提示中复制和粘贴，如下所示）：

＆＃34;设置encryptedFileSize = 50此时是意外的。＆＃34;

收到错误讯息：

D:\BackupSchedule\BackupScripts\TestScripts>FOR /F "usebackq" %A IN ('"DailyBack
up.20161230-15-42.7z"') DO set encryptedFileSize=%~zA

D:\BackupSchedule\BackupScripts\TestScripts>set encryptedFileSize=
50 was unexpected at this time.
D:\BackupSchedule\BackupScripts\TestScripts>    IF  GTR 50 (
