Vista - How do I use the property of a property?

I can do:

dir | ft LastWriteTime

and I get a list of the last write time for each file in the current
directory. But, when I do:

dir | ft LastWriteTime.Hour

I get a blank line for each file in the directory.

Also, when I do:

dir | ft LastWriteTime.ThisIsInvalid

I get the same results as when I use the .Hour property even though I'm
using an invalid property.

I think I'm missing something very basic, how do I use the property of a
property?

Thanks,

You can use a calculated property:

dir | ft @{label='Hour'; expression = {$_.LastWriteTime.Hour}} -a

dir | ft LastWriteTime, @{label='Hour'; expression = {$_.LastWriteTime.Hour}} -a

Hello John,


Try this:

PS > dir | ft {$_.LastWriteTime.Hour} -auto


To get a nice readable coulmn name use a the full calculted property syntax,
see the help for more information:


PS > dir | ft @{label = "Hour";expression={$_.LastWriteTime.Hour}} -auto
