How to Remove ReadOnly Attribute on File Using PowerShell?

Question

How can I remove the ReadOnly attribute on a file, using a PowerShell (version 1.0) script?

Answer 1

You can use Set-ItemProperty:

Set-ItemProperty file.txt -name IsReadOnly -value $false 

or shorter:

sp file.txt IsReadOnly $false 

Answer 2

$file = Get-Item "C:\Temp\Test.txt"  if ($file.attributes -band [system.IO.FileAttributes]::ReadOnly)   {     $file.attributes = $file.attributes -bxor [system.IO.FileAttributes]::ReadOnly     }   

The above code snippet is taken from this article

UPDATE Using Keith Hill's implementation from the comments (I have tested this, and it does work), this becomes:

$file = Get-Item "C:\Temp\Test.txt"  if ($file.IsReadOnly -eq $true)   {     $file.IsReadOnly = $false    }
