清理指定后缀名文件的 powerhsell 小脚本
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：
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!"$item if (IsArchiveFile($item)) { write-host -ForegroundColor 'Yellow' " * This is a archive file, and it will be remove:" write-host -ForegroundColor 'Green' " "$item deleteFileByPath($item) } else { write-host -ForegroundColor 'Gray' " - But not a archive file" } } # 对于文件 } elseif ([Path]::is_filename($item)) { write-host -ForegroundColor 'DarkGreen' "=> This is a file!"$item if (IsArchiveFile($item)) { write-host -ForegroundColor 'Yellow' " * This is a archive file, and it will be remove!" write-host -ForegroundColor 'Green' " "$item deleteFileByPath($item) } else { write-host -ForegroundColor 'Gray' " - But not a archive file" } } } }
4.正则匹配压缩文件后缀名 - 筛选压缩文件
function IsArchiveFile([string]$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 $isWim return $isAechiveFile }
5.由路径删除文件，失败时提示
function deleteFileByPath([string]$file_path) { try{ Remove-Item -Path $file_path write-host -ForegroundColor 'Blue' "Ok, this file has been removed!" return $True }catch{ Write-Warning "An error occurred While delete file:" Write-Host $_ return $False } }
