[CMD] 批次語法檢查檔案大小

set file="test.cmd"

set maxbytesize=1000

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

if %size% LSS %maxbytesize% (

    echo.File is ^< %maxbytesize% bytes

) ELSE (

    echo.File is ^>= %maxbytesize% bytes

)




delfile.bat:

FOR %%F IN ("C:\abc\a*b") DO (IF %%~zF LSS 1 del %%F)

如果要用另一個bat去呼叫，前面不用加 call

call C:\abc\delsize0activity.bat > D:\abc\delsize0.log

EQU – 等於
NEQ – 不等於
LSS – 小於
LEQ – 小於或等於
GTR – 大於
GEQ – 大於或等於
