批处理命令 | 改变字体编码、右键菜单上以管理员身份运行CMD

1. 回显相关命令

命令	作用
`@echo on`	打开回显
`@echo off`	关闭回显

提示：
当不想批处理文件中的命令一行一行在DOS中显示出来时可以使用@echo off，将其放于程序的最上方就行了

2.字体编码

chcp <number>

提示：

UTF-8 65001

GB2312 936

参阅：代码页标识符

4. 命令行结果不显示

若要命令行结果不显示，则输出重定向到null
<command> >nul
例如：chcp 65001 >nul

5.自动以管理员身份运行bat

第一种

@echo off
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
if '%errorlevel%' NEQ '0' (
goto UACPrompt
) else ( goto gotAdmin )
:UACPrompt
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"
"%temp%\getadmin.vbs"
exit /B
:gotAdmin
if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )

第二种


fltmc>nul||cd/d %~dp0&&mshta vbscript:CreateObject("Shell.Application").ShellExecute("%~nx0","%1","","runas",1)(window.close)&&exit

第三种

提醒：将自己代码放在最后面即可以管理员身份运行批处理命令

6. 右键菜单运行CMD

第一种：批处理命令

@echo off
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
if '%errorlevel%' NEQ '0' (
goto UACPrompt
) else ( goto gotAdmin )
:UACPrompt
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"
"%temp%\getadmin.vbs"
exit /B
:gotAdmin
if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )

@echo off
echo.
reg add HKEY_CLASSES_ROOT\Directory\Background\shell\OpenCMDHere /v icon /t REG_SZ /d C:\windows\system32\cmd.exe /f || echo **失败**
echo.
reg add HKEY_CLASSES_ROOT\Directory\Background\shell\OpenCMDHere /v ShowBasedOnVelocityId /t REG_DWORD /d 0x00639bc8 /f || echo **失败**
echo.
reg add HKEY_CLASSES_ROOT\Directory\Background\shell\OpenCMDHere\command /ve  /t REG_SZ /d "cmd.exe /s /k pushd \"%%V\" " /f || echo **失败**
echo.
pause

第二种：reg文件

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\Background\shell\OpenCMDHere]
"ShowBasedOnVelocityId"=dword:00639bc8

[HKEY_CLASSES_ROOT\Directory\Background\shell\OpenCMDHere\command]
@="cmd.exe /s /k pushd \"%V\""

reg add HKEY_CLASSES_ROOT\Directory\Background\shell\OpenCMDHere /v icon /t REG_SZ /d C:\windows\system32\cmd.exe /f

6. 右键菜单以管理员身份运行CMD

Windows Registry Editor Version 5.00

[-HKEY_CLASSES_ROOT\Directory\shell\runas]
[HKEY_CLASSES_ROOT\Directory\shell\runas]
@="Run cmd as Admin"
"HasLUAShield"=""

[HKEY_CLASSES_ROOT\Directory\shell\runas\command]
@="cmd.exe /s /k pushd \"%V\""

[-HKEY_CLASSES_ROOT\Directory\Background\shell\runas]
[HKEY_CLASSES_ROOT\Directory\Background\shell\runas]

[-HKEY_CLASSES_ROOT\Drive\shell\runas]
[HKEY_CLASSES_ROOT\Drive\shell\runas]

"HasLUAShield"=""

[HKEY_CLASSES_ROOT\Drive\shell\runas\command]
@="cmd.exe /s /k pushd \"%V\""

[-HKEY_CLASSES_ROOT\LibraryFolder\background\shell\runas]
[HKEY_CLASSES_ROOT\LibraryFolder\background\shell\runas]
"HasLUAShield"=""
@="Run cmd as Admin"

[HKEY_CLASSES_ROOT\LibraryFolder\background\shell\runas\command]
