如何显示全名的长度

Question

how can i get the length of the full path of a filename?

I am getting all the files recursively in a directory structure succesfully, and now I am trying to get the length of the fullpath:

get-childitem y:\ -rec | where {!$_.PSIsContainer} |
select-object FullName, LastWriteTime, $($_.fullname).length | export-csv -notypeinformation -delimiter '|' -path file.csv

my issue is with this: $($_.fullname).length :

Select-Object : Null parameter. Expecting one of the following types: {System.String, System.Management.Automation.Scri ptBlock}. At line:2 char:14
+ select-object <<<<  FullName, LastWriteTime, $($_.fullname).length | export-csv -notypeinformation -delimiter '|' -pa th file.csv
    + CategoryInfo          : InvalidArgument: (:) [Select-Object], NotSupportedException
    + FullyQualifiedErrorId : DictionaryKeyUnknownType,Microsoft.PowerShell.Commands.SelectObjectCommand

how would i get the length of the fullname of the file?

Answer 1

Create a custom expression in the select cmdlet. Like this:

get-childitem y:\ -rec | where {!$_.PSIsContainer} |
select-object FullName, LastWriteTime, @{n="FullNameLength";e={ $_.fullname.length }} |
export-csv -notypeinformation -delimiter '|' -path file.csv

n = name and e = expression. You can also use their full name. l or label is an alternative to name . No mather which way you write them, you end up with a custom property. : )
