Question

Windows PowerShell现在已经很长时间了。与优质的旧Windows外壳相比，它更强大。是否有任何脚本用于加速和简化您作为开发人员的日常工作？如果你可以用PowerShell做魔术 - ＆gt;请与我们分享！

更新 PowerShell Community Extensions不是真正的脚本，而且非常有用。该软件包包含许多新的Cmdlet和PowerShell修改。

我把一堆脚本放在一起，在命令行中使用Subversion。他们中的大多数只使用--xml选项以对象形式放置各种信息。以下是几个例子：

function Get-SvnStatus( [string[]] $Path   = ".", 
                        [string]   $Filter = "^(?!unversioned|normal|external)", 
                        [switch]   $NoFormat )
{
    # powershell chokes on "wc-status" and doesn't like two definitions of "item"
    [xml]$status = ( ( Invoke-Expression "svn status $( $Path -join ',' ) --xml" ) -replace "wc-status", "svnstatus" ) `
        -replace "item=", "itemstatus="

    $statusObjects = $status.status.target | Foreach-Object { $_.entry } | Where-Object { 
        $_.svnstatus.itemstatus -match $Filter 
    } | Foreach-Object {
        $_ | Select-Object @{ Name = "Status"; Expression = { $_.svnstatus.itemstatus } }, 
                           @{ Name = "Path";   Expression = { Join-Path ( Get-Location ) $_.path } }
    } | Sort-Object Status, Path

    if ( $NoFormat )
    {
        $statusObjects
    }
    else
    {
        $statusObjects | Format-Table -AutoSize
    }
}

function Get-SvnLog( [string] $Path = ".", 
                     [int]    $Revision, 
                     [int]    $Limit = -1, 
                     [switch] $Verbose, 
                     [switch] $NoFormat )
{
    $revisionString = ""
    $limitString = ""
    $verboseString = ""

    if ( $Revision )
    {
        $revisionString = "--revision $Revision"
    }

    if ( $Limit -ne -1 )
    {
        $limitString = "--limit $Limit"
    }

    if ( $Verbose )
    {
        $verboseString = "--verbose"
    }

    [xml]$log = Invoke-Expression "svn log $( $path -join ',' ) --xml $revisionString $limitString $verboseString"

    $logObjects = $log.log.logentry | Foreach-Object {
        $logEntry = $_

        $logEntry | Select-Object `
            @{ Name = "Revision"; Expression = { [int]$logEntry.revision } },
            @{ Name = "Author"; Expression = { $logEntry.author } },
            @{ Name = "Date"; 
               Expression = {
                   if ( $NoFormat )
                   {
                       [datetime]$logEntry.date
                   }
                   else
                   {
                       "{0:dd/MM/yyyy hh:mm:ss}" -f [datetime]$logEntry.date
                   }
               } },
            @{ Name = "Message"; Expression = { $logEntry.msg } } | 
        Foreach-Object {
            # add the changed path information if the $Verbose parameter has been specified
            if ( $Verbose )
            {
                $_ | Select-Object Revision, Author, Date, Message,
                    @{ Name = "ChangedPaths"; 
                       Expression = {
                           $paths = $logEntry.paths.path | Foreach-Object {
                               $_ | Select-Object `
                                   @{ Name = "Change"; 
                                      Expression = { 
                                          switch ( $_.action )
                                          {
                                              "A" { "added" }
                                              "D" { "deleted" }
                                              "M" { "modified" }
                                              "R" { "replaced" }
                                              default { $_.action }
                                          }
                                      } },
                                   @{ Name = "Path"; Expression = { $_."#text" } }
                           }

                           if ( $NoFormat )
                           {
                               $paths
                           }
                           else
                           {
                               ( $paths | Sort-Object Change | Format-Table -AutoSize | Out-String ).Trim()
                           }
                       } 
                     }
            }
            else
            {
                $_
            }
        }
    }

    if ( $NoFormat )
    {
        $logObjects
    }
    else
    {
        $logObjects | Format-List
    }
}

我分别将这些别名用于svns和svnl。我谈了几个其他人here。

我一直使用这个，因为Windows资源管理器搜索文件内容永远不适合我：

Get-ChildItem -Recurse -Filter *.extension |
    Select-String -List somestring |
    Format-Table filename,linenumber -AutoSize

只需将“extension”替换为您感兴趣的文件类型的文件扩展名（或完全删除-Filter参数），并将“somestring”替换为您要在文件中找到的文本。

Answer 3

这不是一个脚本，但一般来说，了解何时可以通过名称和位置来缩短参数是有帮助的。

按名称，PowerShell只需要将其缩小到一个。例如，gci -r有效但gci -f可能是-filter或-force。

在没有参数标签的情况下指定的值将按位置应用。因此，如果您想指定-filter，您可以这样做：

gci -r -fil *.cs

或者.位置-path，以便您也可以在位置指定-filter：

gci -r . *.cs

任何时候你看到正确大写的东西，这表明我已经使用了TAB完成。你应该知道PS会为你完成哪些事情 - 这在V2中非常好。

任何时候你看到小写的别名，这是我从内存中输入的东西。你也应该记住它。

# grep example - find all using statements
dir -r -fil *cs | ss using
# advanced version
dir -fil *cs -r | ss '^using[^\(]+' | gpv line | sort -unique

# figure out how to query for drive free space (emphasis on "figure out" -- I can never remember things like this)
gcm *drive*
help Get-PSDrive -full
Get-PSDrive | gm
# now use it
Get-PSDrive | ? { $_.free -gt 1gb }

# pretend mscorlib.dll is an assembly you're developing and want to do some ad-hoc testing on
$system = [system.reflection.assembly]::LoadFile("c:\blah\...\mscorlib.dll")
$system | gm
$types = $a.GetTypes()    
$types | gm
$types | ? { $_.ispublic -and $_.basetype -eq [system.object] } | sort name
$sbType = $types | ? { $_.name -eq "StringBuilder" }
# now that we've loaded the assembly, we could have also done:
#   $sbType = [system.text.stringbuilder]
# but we may not have known it was in the Text namespace
$sb = new-object $sbType.FullName
$sb | gm
$sb.Append("asdf")
$sb.Append("jkl;")
$sb.ToString()

每个开发人员应该知道的PowerShell脚本
