Expand-Gzip Cmdlet

Parameters Output Objects Configuration Settings

The Expand-Gzip cmdlet implements a decompressor for GZIP archives.

Syntax

Expand-Gzip [parameters]

Remarks

The cmdlet implements a gzip decompressor compliant to RFC 1952 and compatible with the UNIX gzip and gunzip utilities.

To scan an archive, set the Input parameter to the archive to examine and do not set the Output parameter. A ZipFileInfo object will be returned.

If the Output parameter is set, the cmdlet will attempt to extract the archive to the specified location. A ZipFileInfo object will be returned indicating the success of the operation.

The cmdlets support pipeline input for some of their parameters. Prebuilding an object and piping it to the cmdlet is very useful, but should be used with caution to prevent security conflicts. Steps have been taken to decrease the risk of a possibly accidental pipe to the cmdlet, for instance, the Credential parameter cannot be piped to the cmdlet and must be specified manually.

# scan an archive
Expand-Gzip -Input "simple.gz" 
# extract file
Expand-Gzip -Input "C:\simple.gz" -Output "C:\temp"
