PowerShell: unzip, untar

unzip

# unarchive to current dir
Expand-Archive xyz.zip

# specify a target dir
Expand-Archive -Path c:/Users/xah/xyz.zip -DestinationPath  c:/Users/xah/out/

# using literal path, no expansion
Expand-Archive -LiteralPath c:/Users/xah/xyz.zip -DestinationPath  c:/Users/xah/out/

• by default, Expand-Archive will create a parent folder to contain the archive.
• To not create a parent folder, use -PassThru
• if -DestinationPath is not given, it expands to the current directory.

example script:

# unzip all *nb.zip files to a dir named x
dir * -Recurse -Include "*nb.zip" | Expand-Archive -PassThru -DestinationPath x
