Logging actions of my powershell into a file - powershell

Question

I'm actually doing a script to replace every "o" into my folder/files names into "0"
Here is my simple script :
Get-ChildItem -recurse |`
Where-Object { $_.name -match 'o' } |`
Rename-Item -NewName { $_name -replace 'o', '0' }
It is working but now I want to log into a file every files/folder that have changed.
So basicly I want to add a function to write the name of my file before and after being renamed.
For example, for the "BEFORE name", I tried to add this command after the Where-Object pipe :
Add-content $MylogFile
It succed to log every files having a 'o' inside but WITHOUT their path. And having a log of 1000+ files without their path is useless...
DO you have any idea to simply log the before/after name of each file that have been renamed by the script WITH their path ?
Thanks in advance !

You just need to store the original search into a variable then iterate over it. The following should do what you want:
If you want to rename only files:
$files = Get-ChildItem -recurse | Where-Object { $_.PSIscontainer -eq $false -and $_.name -match 'o' }
$files | % {
$newname = $_.name -replace 'o', '0'
write-host "Before: $($_.fullname)"
write-host "After: $newname"
$_ | Rename-Item -NewName $newname
}
To rename files AND folders:
$files = Get-ChildItem -recurse | Where-Object { $_.PSIscontainer -eq $false -and $_.name -match 'o' }
$files | % {
$newname = $_.name -replace 'o', '0'
write-host "Before: $($_.fullname)"
write-host "After: $newname"
$_ | Rename-Item -NewName $newname
}
$dirs = Get-ChildItem -recurse | Where-Object { $_.PSIscontainer -eq $true -and $_.name -match 'o' }
$dirs | % {
$newname = $_.name -replace 'o', '0'
write-host "Dir Before: $($_.fullname)"
write-host "Dir After: $newname"
$_ | Rename-Item -NewName $newname
}
