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

If you happen to be using the PowerShell Community Extensions:

PS> Set-Writable test.txt
PS> dir . -r *.cs | Set-Writable
# Using alias swr
PS> dir . -r *.cs | swr

You can do the opposite like so:

PS> dir . -r *.cs | Set-ReadOnly
# Using alias sro
PS> dir . -r *.cs | sro
