$sharename = Read-Host "Enter path" 
if ($sharename -eq "c$") 
    {

Answer 1

使用像这样通配符-match运营商正则表达式，或-like，

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

正则表达式是建立像这样，

\\ -> \ 
\\ -> \ 
\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
