我如何问PowerShell的东西在哪里?
例如,"which notepad",它根据当前路径返回notepad.exe运行的目录。

我对Which函数的命题是:
function which($cmd) { get-command $cmd | % { $_.Path } }
PS C:\> which devcon
C:\local\code\bin\devcon.exe

我喜欢Get-Command |格式列表,或更短,使用别名的两个,只用于powershell.exe:
gcm powershell | fl
你可以找到这样的别名:
alias -definition Format-List
制表符补全使用gcm。
一次列出所有选项:
set-psreadlineoption -editmode emacs
当我开始在PowerShell中定制我的个人资料时,我做的第一个别名是“which”。
New-Alias which get-command
要将此添加到您的配置文件中,请键入以下内容:
"`nNew-Alias which get-command" | add-content $profile
最后一行开头的' n是为了确保它将作为一个新行开始。
如果你有勺子,你可以安装一个直接克隆:
scoop install which
which notepad
我有这个高级功能在我的PowerShell配置文件:
function which {
<#

$cmd = Get-Command $name

switch ($cmd.CommandType) {
"Alias" { "{0}: Alias for ({1})" -f $cmd.Name, (. { which $cmd.Definition } ) }
"Application" { $cmd.Source }
"Cmdlet" { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
