Walk a directory/Recursively: Difference between revisions

=={{header|PowerShell}}==

In PowerShell the <code>Get-ChildItem</code> cmdlet allows for recursive filtering on file names with simple wildcards:

<lang powershell>Get-ChildItem -Recurse -Include *.mp3</lang>

For more complex filtering criteria the result of <code>Get-ChildItem</code> can be piped into the <code>Where-Object</code> cmdlet:

<lang powershell>Get-ChildItem -Recurse |

Where-Object { $_.Name -match 'foo[0-9]' -and $_.Length -gt 5MB }</lang>

To perform an action on every matching file the results can be piped into the <code>ForEach-Object</code> cmdlet:

<lang powershell>Get-ChildItem -Recurse |

Where-Object { $_.Name -match 'foo[0-9]' } |

ForEach-Object { ... }</lang>

''Note:'' To include only ''files'' instead of directories too each of the above needs an additional<code>Where-Object</code> filter:

<lang powershell>| Where-Object { !$_.PSIsContainer }</lang>
