运行批处理文件时在命令提示符下显示的隐藏命令

Question

I created a batch file like given below , but this is not getting hidden in command prompt evev though echo off is used.

I doesn't want csv file or any other file to display in command prompt. it is also showing warning using password in command prompt is insecure, please help me.

this batch file when run in command prompt produces W P.xls as output file

@echo off
    echo %1 
    echo SET @bdate := "%1"; > a.sql
    copy /b a.sql + bdate.sql out.sql
    mysql --user="root" --database="abc" --password="123" < "D:\New   Folder\out.sql"
    java -jar csvtoxls.jar
    del out.sql
    del ws.csv
    rename "W P.xls" "W P"%1".xls"

Add @ sign for commands you want to hide.

Also add > nul in front of command if you don't want show output.
