Windows PowerShell持续历史记录

Question

因此，我发现这个优秀的方法persisting history in Windows PowerShell。

# Persistent History 
# Save last 200 history items on exit 
$MaximumHistoryCount = 200  
$historyPath = Join-Path (split-path $profile) history.clixml 

# Hook powershell's exiting event & hide the registration with -supportevent (from nivot.org) 
Register-EngineEvent -SourceIdentifier powershell.exiting -SupportEvent -Action { 
    Get-History -Count $MaximumHistoryCount | Export-Clixml (Join-Path (split-path $profile) history.clixml) 
} 

# Load previous history, if it exists 
if ((Test-Path $historyPath)) { 
    Import-Clixml $historyPath | ? {$count++;$true} | Add-History 
    Write-Host -Fore Green "`nLoaded $count history item(s).`n" 
} 

# Aliases and functions to make it useful 
New-Alias -Name i -Value Invoke-History -Description "Invoke history alias" 
Rename-Item Alias:\h original_h -Force 
function h { Get-History -c $MaximumHistoryCount } 
function hg($arg) { Get-History -c $MaximumHistoryCount | out-string -stream | select-string $arg } 

然而，当我粘贴到我的$配置文件，重新启动PowerShell中，我得到了 以下错误

 
Register-EngineEvent : Missing an argument for parameter 'Action'. Specify a parameter of type 
'System.Management.Automation.ScriptBlock' and try again. 
At D:\path\to\WindowsPowerShell\Microsoft.PowerShell_profile.ps1:20 char:73 
+ Register-EngineEvent -SourceIdentifier powershell.exiting -SupportEvent -Action 
+                   ~~~~~~~ 
    + CategoryInfo   : InvalidArgument: (:) [Register-EngineEvent], ParameterBindingException

Answer 1

这是我使用的时候我坚持我的历史使用的代码

$historyPath = Join-Path (split-path $profile) "history-$(Get-Date -f o).clixml" 
Register-EngineEvent -SourceIdentifier powershell.exiting -SupportEvent -Action { 
    Get-History | Export-Clixml $historyPath 
}.GetNewClosure() 

GetNewClosure()用于捕获变量IIRC的$historyPath。

与此问题非常相关的是“如何使用向上/向下箭头访问我的历史记录？”该PSReadLine模块解决了这个：

Install-Package PSReadLine 

然后加：

Import-Module PSReadLine 

要将$profile。

好视topicstarter代码的组合和微微一变答案由史蒂芬便士，这是代码的完整片这是为我工作

################# Persistent History ############ 
# Save last 200 history items on exit 
$MaximumHistoryCount = 200  
$historyPath = Join-Path (split-path $profile) history.clixml 

# Hook powershell's exiting event & hide the registration with -supportevent (from nivot.org) 
Register-EngineEvent -SourceIdentifier powershell.exiting -SupportEvent -Action { 
     Get-History | Export-Clixml $historyPath 
}.GetNewClosure() 

# Load previous history, if it exists 
if ((Test-Path $historyPath)) { 
    Import-Clixml $historyPath | ? {$count++;$true} | Add-History 
    Write-Host -Fore Green "`nLoaded $count history item(s).`n" 
} 

# Aliases and functions to make it useful 
New-Alias -Name i -Value Invoke-History -Description "Invoke history alias" 
Rename-Item Alias:\h original_h -Force 
function h { Get-History -c $MaximumHistoryCount } 
function hg($arg) { Get-History -c $MaximumHistoryCount | out-string -stream | select-string $arg }
