unzip file using 7z in powershell

问题

What is the command to unzip a file using 7z in powershell?

set-alias sz "$env:ProgramFiles\7-Zip\7z.exe"
sz x  $zipfilePath $destinationUnzipPath -aoa -r;

The command works fine but it says no files to process, everything is Ok rather than unzipping the file?

回答1:

This finally worked for me sz x -o$destinationUnzipPath $zipfilePath -r ;

回答2:

Aliases are not meant for that, they are meant to proxy other commands, not commands + parameters.

To achieve what you want you would need to use a functions:

function sz($args) {
    Start-Process "$env:ProgramFiles\7-Zip\7z.exe" -ArgumentList $args
}

I didn't want to use aliases, functions or Start-Process. After a little looking around the web, I've found this gem (and I can't remember where):

& ${env:ProgramFiles}\7-Zip\7z.exe x $zipfilePath "-o$($destinationUnzipPath)" -y

And you can add a > $null at the end if you don't want to see 7z's messages!
