[英]Batch file to delete files and folder
我正在寻找一种删除具有特定名称的文件夹中包含的文件,然后再删除该文件夹的方法。
我知道有forfiles命令行可用于删除文件,我只是不知道如何将文件夹名称放入路径。 该文件夹是根据创建日期命名的,我想删除7天的文件夹。 该文件夹的格式为yyyymmdd。
基本上我需要
forfiles /P "C:\backups\[DATE 7 DAYS AGO IN yyyymmdd format]" /S /M *.BAK /C "cmd /c del @path"
然后我想删除该文件夹后
forfiles /P "C:\backups\[DATE 7 DAYS AGO IN yyyymmdd format]" /S /C "cmd /c IF @isDir == TRUE rd @path"
我该如何填写[DATE 7 DAYS ...]。
1-为什么要尝试先删除文件,然后删除Tolfer? 如果先删除文件夹,则可以在更短的时间内完成相同的操作...
第二- 我认为您不能成批地这样做,并非没有错误,您需要提取(知道)至少要用于目的的“ X”年的日历天,而批处理中没有提取信息的方法,或者精通数学,知道如何获取过去几年的日历日期。
因此,您需要一种可以访问Microsoft.Time和数据库并进行比较的逼真的脚本语言。 (Ruby,Python,Perl,所有您想要的东西都少了批处理)
顺便说一句,存在一些由RobVanDeerWoud编写的超高级atricmetics batfile代码,用于“玩”事物,例如,使用此脚本可以在日期中添加“ X”天,看看是否可以修改以扣除天数:

尝试使用rmdir
(在命令提示符下键入rmdir /?
获得帮助)
好吧,所以我遵循了Elektro Hacker的建议,最后通过powershell进行了修改,如下所示:
$currentDate = get-date
$backupPath = "C:\backup\"
$logFilePath = ("$backupPath" + "ScriptAndQuery\Logs\")
$dailyLog = ("$logFilePath" + "daily_delete.txt")
$weeklyLog = ("$logFilePath" + "weekly_delete.txt")
$monthlyLog = ("$logFilePath" + "monthly_delete.txt")
$dailyBackup = ("$backupPath" + "Daily\")
$weeklyBackup = ("$backupPath" + "Weekly\")
$monthlyBackup = ("$backupPath" + "Monthly\")
$addDateToFile = "TRUE"
get-childitem $dailyBackup |? { $_.psiscontainer -and $_.lastwritetime -le ($currentDate).adddays(-7) } |% {
try {
if($addDateToFile -eq "TRUE") {
Add-Content "$dailyLog" "$currentDate`r`n"
$addDateToFile = "FALSE"
}
$fullPath = $_.FullName
remove-item $fullPath -Recurse -force
if (test-path $fullPath) {
Add-Content "$dailyLog" "FAILED TO DELETE $fullPath`n"
} else {
Add-Content "$dailyLog" "SUCCESSFULLY DELETED $fullPath`n"
}
}
catch {
Add-Content "$dailyLog" "Exception Occurred: $_.Exception`n"
}
}
if ($addDateToFile -eq "FALSE") {
Add-Content "$dailyLog" "`r`n"
$addDateToFile = "TRUE"
}
get-childitem $weeklyBackup |? {$_.psiscontainer -and $_.lastwritetime -le ($currentDate).adddays(-28)} |% {
try {
if ($addDateToFile -eq "TRUE") {
Add-Content "$weeklyLog" "$currentDate`r`n"
$addDateToFile = "FALSE"
}
$fullPath = $_.FullName
remove-item $fullPath -Recurse -force
if (test-path $fullPath) {
Add-Content "$weeklyLog" "FAILED TO DELETE $fullPath`n"
} else {
Add-Content "$weeklyLog" "SUCCESSFULLY DELETED $fullPath`n"
}
}
catch {
Add-Content "$weeklyLog" "Exception Occurred: $_.Exception`n"
}
}
if ($addDateToFile -eq "FALSE") {
Add-Content "$weeklyLog" "`r`n"
$addDateToFile = "TRUE"
}
get-childitem $monthlyBackup |? {$_.psiscontainer -and $_.lastwritetime -le ($currentDate).adddays(-365)} |% {
try {
if($addDateToFile -eq "TRUE") {
Add-Content "$monthlyLog" "$currentDate`r`n"
$addDateToFile = "FALSE"
}
$fullPath = $_.FullName
remove-item $fullPath -Recurse -force
if (test-path $fullPath) {
Add-Content "$monthlyLog" "FAILED TO DELETE $fullPath`n"

}
catch {

}
}
if ($addDateToFile -eq "FALSE") {
Add-Content "$monthlyLog" "`r`n"
}
在此,我有3种不同的备份发生(每天,每周和每月)。 因此,基本上,我从每天删除一个星期的所有文件,每周一个月的文件和每月一个的文件中删除所有文件。 我还将将每个日期和文件夹删除的日期和文件夹打印到文件,或者在文件夹仍然存在或发生异常的情况下显示失败消息。 然后,该脚本每天运行一次,到目前为止运行良好。
谢谢DMan
