set /p username=Enter username:

echo Select permissions :

echo N  - no access
echo F  - full access
echo M  - modify access
echo RX - read and exe
echo R  - read-only acc
echo W  - write-only ac
echo D  - delete access

echo.

set /p perm=Enter permissions:

if %perm%==F

icacls "C:\Users\%username%" /grant:r "%username%:(OI)(CI)F"

当我运行此文件并输入权限为F时,它显示此错误：命令的语法不正确.但如果我直接在cmd中运行相同的命令它完美地工作.那么,我如何更正批处理文件中的命令,以便它运行没有任何问题？
