如何使用PowerShell时间记录脚本？
#initialization
$timeInterval = 30 #监测间隔
$record = @{"Coding" = 0; "Outlook Email" = 0; "Gmail" = 0; "Google Reader" = 0; "BBS" = 0; "Other Internet" = 0; "Documents" = 0;}
$count = 0
$date = date -format "yyyyMMdd"
#try to resume
if (test-path "d:\temp\timeRecord$date.txt") {
gc "d:\temp\timeRecord$date.txt" | % {if ($_ -match "\w+\s+\d+") {
$groups = [Regex]::Match($_, "^(\w+\s?\w+)\s+(\d+)").Groups;
$record[$groups[1].Value] = [int]::Parse($groups[2].Value);
}}
}
#start to monitor
while ($true)
{
$titles = ps | ? {$_.MainWindowTitle} | select MainWindowTitle
$titles | % {
if ($_ -match "Google 阅读器 - Windows Internet Explorer") {$record["Google Reader"]++;}
else {if ($_ -match "Gmail - Windows Internet Explorer") {$record["Gmail"]++;}
else {if ($_ -match "Internet Explorer") {$record["Other Internet"]++;}
else {if ($_ -match "Visual Studio") {$record["Coding"]++;}
else {if ($_ -match "Microsoft Word") {$record["Documents"]++;}
else {if ($_ -match "Microsoft Office OneNote") {$record["Documents"]++;}
else {if ($_ -match "Microsoft PowerPoint") {$record["Documents"]++;}
else {if ($_ -match "Message (HTML)") {$record["Outlook Email"]++;}
else {if ($_ -match "bbs") {$record["BBS"]++;}
}}}}}}}}
}
sleep($timeInterval)
$count = ($count + 1) % 10 #为了防止数据丢失，每10次记录写入文件一次
if ($count -eq 0) {$record > "d:\temp\timeRecord$date.txt"}
}
为了解技术思路,研究了一下powershell.
整个开发与部署过程如下:
1.下载WindowsXP-KB926139-v2-x86-ENU
安装powershell环境;
2.按照代码要求,写一个简单的脚本;
3. 运行powershell时,同 bat是有区别的.注意以下方法:
1) 解除限制:
set-executionpolicy Unrestricted
2) 将文件名保存为ps1
3) 通过以下方法运行(假如文件名是c:a.ps1)
PS C:> .a
[@more@]
示例代码:
function foo ( [int] $x)
{
$x = $x + 1
echo $x
}
foo (1 )
