按文件名末尾的数字对文件进行排序

Question

I need help with a tricky task I have.

I have a list of *.xml files which have the same ending. The names below show only the naming convention rule.

EEEEEEEEEE-JJJ-ZZZZZ_DDDDD-XML--0000001629358212.xml

EEEEEEEEEE-JJJ-OOOOOO-XML--0000001533506936.xml

EEEEEEEEEE-JJJ-AAAAAA-XML--0000001572627196.xml

Filename length maybe is different but it's important for me to sort it by this number in the end. With SQL syntax it would be easier but I need a PS solution).

Sort-Object by LastWriteTime works better than other simple ways - but when it comes to a few files with the same hh:mm PS mixes the order.

At the beginning of the chains of steps that should happen with these files, I remove a time stamps from the beginning of each file name. I was able to do it with this:

dir *EEEEEEEEEE*.xml | Rename-Item -NewName {$_.name.substring($_.BaseName.IndexOf("EEEEEEEEE"))}

But I'm unable to write something similar for sorting.

Maybe someone can advise how to solve it? Maybe You have more experience with PS Substring.

Thanks in advance.

Answer 1

Read and follow Sort-Object , scrolling down to the -Property parameter:

…
The Property parameter's value can be a calculated property. To create a calculated property, use a hash table.

Valid keys for a hash table are as follows:

 expression - <string> or <script block> ascending or descending - <boolean>

For more information, see about_Calculated_Properties .

Read the Examples section as well. Use

Get-ChildItem -File -Filter "*EEEEEEEEEE*-*.xml" |
  Sort-Object -Property @{Expression = { ($_.BaseName -split '-')[-1] }}

Answer 2

Thank you guys for the help.

I used this line below and it worked in my case. GCI EEEEEEEEEE*.xml | Sort {$_.Name.substring($_.Name.Length - 20,14)} GCI EEEEEEEEEE*.xml | Sort {$_.Name.substring($_.Name.Length - 20,14)} It reads only the number at the end of the file name and sorts the files in the way I need.

Best regards
