1.介绍

在运维值班每天都需要从系统导出这种数据，压缩好放在工作电脑上，解压用脚本做汇总。但是长期都没删除各个日期下的压缩包。几年下来，有上千个目录，也不知道哪些目录中有没有删除的压缩包。一个一个手删太累了，不妨做个 powershell 小脚本一键搞定吧。

这个脚本同样适合于删除目录中其它后缀名的文件。

相关工具代码

后文用到了两个工具模块，这两个模块在我之前的两篇博客中有完整介绍和源代码：

• 《【运维】PowerShell编程 目录文件相关方法的封装与案例详解》

• 《[运维技术]PowerShell中实现一个最基本的日志器logger》

2.目录结构

项目结构

日志结构

3.主函数部分

为了以后方便指定仅针对某个年份，或者修改为其它需要考虑年份的脚本，可以不要直接读取日志根目录中所有文件，而是逐个遍历所有年份下的文件夹：

function main($BASE_DIR) {$logger.Trace("Start compute...")$logger.Trace($BASE_DIR)$items = [Path]::get_items($BASE_DIR)foreach ($item in $items) {  Write-host -ForegroundColor 'Gray' "=========================================================================================================="# 对于目录$logger.Info("Current folder is: " + $item)if ([Path]::is_dirname($item)) {write-host -ForegroundColor 'DarkBlue' "=====> This is a folder!"foreach ($item in [Path]::get_descendants($item) ) {write-host -ForegroundColor 'DarkGreen' "=> This is a file!"$itemif (IsArchiveFile($item)) {write-host -ForegroundColor 'Yellow' " * This is a archive file, and it will be remove:"write-host -ForegroundColor 'Green' "  "$itemdeleteFileByPath($item)}else {write-host -ForegroundColor 'Gray' " - But not a archive file"}}# 对于文件}elseif ([Path]::is_filename($item)) {write-host -ForegroundColor 'DarkGreen' "=> This is a file!"$itemif (IsArchiveFile($item)) {write-host -ForegroundColor 'Yellow' " * This is a archive file, and it will be remove!"write-host -ForegroundColor 'Green' "  "$itemdeleteFileByPath($item)}else {write-host -ForegroundColor 'Gray' " - But not a archive file"}}}
}

4.正则匹配压缩文件后缀名 - 筛选压缩文件

function IsArchiveFile([string]$file_path) {$is7z = $file_path -match "\\.7z$"$isZip = $file_path -match "\\.zip$"$isTar = $file_path -match "\\.tar$"$isWim = $file_path -match "\\.wim$"$isAechiveFile = $is7z -or $isZip -or $isTar -or $isWimreturn $isAechiveFile
}

5.由路径删除文件，失败时提示

function deleteFileByPath([string]$file_path) {try{Remove-Item -Path $file_pathwrite-host -ForegroundColor 'Blue' "Ok, this file has been removed!"return $True}catch{Write-Warning "An error occurred While delete file:"Write-Host $_return $False}
}
