PowerShell 获取某目录下所有的文件、文件夹，同时对获取到的文件路径字符串进行替换处理

前言：

为了将Windows系统下的Java编译文件与linux服务器上的文件进行比较，故进行此文件路径的获取及路径处理。
在只有文件路径 而没有实际文件的情况下的比较。

代码如下：

## grep
#########################################
#检索文件夹所在路径
$findPath = "C:\wang\PowerShell\test\grep_cd_file\source"
#输出文件所在路径
$grepKekka = "C:\wang\PowerShell\test\grep_cd_file\grepKekka.csv"
$grepKekka1 = "C:\wang\PowerShell\test\grep_cd_file\grepKekka1.csv"
$grepKekka2 = "C:\wang\PowerShell\test\grep_cd_file\grepKekka2.csv"
# 清空输出文件
Clear-Content $grepKekka -Force
Clear-Content $grepKekka1 -Force
Clear-Content $grepKekka2 -Force

# 替换 （\ : escape special characters）
$String1 = 'C:\\wang\\PowerShell\\test\\grep_cd_file\\source\\'
$String2 = '/wang/PowerShell/test/grep_cd_file/source/'

# get the files exclude folders
# -Recurse * 用于从指定路径开始递归地获取所有文件和文件夹。通过使用通配符*，可以获取路径下的所有项。
# where{!$_.PSIsContainer} ，用于找出不是文件夹的文件。它将返回在当前路径下所有不是文件夹的文件。
$fileList = Get-ChildItem $findPath -Recurse * | where{!$_.PSIsContainer}
foreach($file in $fileList) {
    #print the file name
    $file.name | Out-File -Width 5000 -FilePath $grepKekka1 -Append

    # print the file fullname
    $file.fullname | Out-File -Width 5000 -FilePath $grepKekka2 -Append
}

<# PowerShell命令-replace $String1, $String2是用来替换字符串中匹配到的部分。其中$String1是要被替换的部分，$String2是替换后的内容。这个命令可以通过正则表达式进行匹配。
在使用-replace命令时，要注意以下几点：
正则表达式最好放在单引号里面，以避免特殊字符被解释为变量。
使用$和^符号时，要区分待匹配对象是单行还是多行。对多行的文件，$表示行的结尾，^表示行的开始。对单行的模式，.会匹配所有字符，包括换行符。
#>
(Get-Content $grepKekka2) -replace $String1, $String2 -replace '\\', '/' | Set-Content $grepKekka
