验证共享名称

Question

如果输入的用户共享名是 c$ 而没有其他内容，我如何使用 powershell 脚本验证？例如从 \\hostname\c$

中提取共享名称

$sharename = Read-Host "Enter path"
if ( $sharename -eq "c$")
  {
    "execute script"
  }
else 
  {
    "ShareName must be c$"
  }

Answer 1

对正则表达式使用 -match 运算符，或像这样对通配符使用 -like，

if ( $sharename -match "\\\w+\c$") {
    "execute script"
  }

正则表达式是这样构建的，

\ -> \
\ -> \
\w+ -> at least one word character
\ -> \
c  -> letter 'c'
$ -> dollar sign

测试用例

$sharename = '\nomatter\c$'
$sharename -match "\\\w+\c$"
True


$sharename = '\nomatter\C$'
$sharename -match "\\\w+\c$"
True


$sharename = '\nomatter\d$'
$sharename -match "\\\w+\c$"
False

$sharename = '\nomatter\cee$'
$sharename -match "\\\w+\c$"
False
