I want to extract all *.Z files in place in their current directories (7-Zip support LZW/UNIX compression).
I can't figure out why this is not working. I know how to use PowerShell to recursively get a full path of a filename and directory in which file resides. I also know how to use 7-zip to extract a file in place. But trying to put these two together is not working. Here's what I have:
Get-ChildItem -Recurse *.Z | foreach ($_) {7z.exe e $_.FullName -o$_.Directory}
I also tried:
Get-ChildItem -Recurse *.Z | foreach ($_) {7z.exe e $_.FullName -o$($_.Directory)}
and
Get-ChildItem -Recurse *.Z | foreach ($_) {7z.exe e $_.FullName -o${_.Directory}}
This is getting the files I want by FullName, and Directory is the correct path (no space between the o and directory is how 7-zip expects the output directory). However, it keeps trying to output the file to the .Z path rather than the directory. I know it is right if I do
Get-ChildItem -Recurse *.Z | Select Directory
that is where I want it to go.
I assume the issue was having no space but not sure why it would get same directory. I even manually defined a variable and passed that with no problems.
So the issue is 7-zip saying no files to process when I want to output to same directory but not sure why, and it seems Directory variable not being passed but file name again which makes no sense. Sample output per file:
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21
Scanning the drive for archives:
1 file, 226 bytes (1 KiB)
Extracting archive: E:\Files\2014\more_cowbell\myfancyunixcompresseddocument.txt.Z
--
Path = E:\Files\2014\more_cowbell\myfancyunixcompresseddocument.txt.Z
Type = Z
No files to process
Everything is Ok
Files: 0
Size: 0
Compressed: 226
It works fine if I specify one specific output directory (no variable), but I want them extracted in place due to many subdirectories and conflicting file names between them.

The -o parameter should be inside a doublequoted string with $($var) for variables:
Get-ChildItem -Recurse *.z | %{ 7z e $_.FullName "-o$($_.Directory)"}
