PathDestination

Expand-GzipArchive
    [-Path] <String[]>
    -Destination <String>
    [-Encoding <Encoding>]
    [-PassThru]
    [-Force]
    [-Update]
    [<CommonParameters>]

LiteralPath

Expand-GzipArchive
    -LiteralPath <String[]>
    [-Raw]
    [<CommonParameters>]

LiteralPathDestination

Expand-GzipArchive
    -LiteralPath <String[]>

DESCRIPTION

The Expand-GzipArchive cmdlet aims to expand Gzip compressed files to a destination path or to the success stream using the GzipStream Class. This cmdlet is the counterpart of Compress-GzipArchive.

EXAMPLES

Example 1: Expanding a Gzip archive to the success stream

PS ..\pwsh> Expand-GzipArchive .\files\file.gz

hello world!

Output goes to the Success Stream when -Destination is not used.

Example 2: Expanding a Gzip archive to a new file

PS ..\pwsh> Expand-GzipArchive .\files\file.gz -Destination .\files\file.txt

# Checking Length Difference
PS ..\pwsh> Get-Item -Path .\files\file.gz, .\files\file.txt |
    Select-Object Name, Length

Name      Length
----      ------
file.gz     3168
file.txt    6857

Example 3: Appending content to an existing file

PS ..\pwsh> Expand-GzipArchive *.gz -Destination .\files\file.txt -Update

Example 4: Expanding a Gzip archive overwritting an existing file

PS ..\pwsh> Expand-GzipArchive *.gz -Destination .\files\file.txt -Force

PARAMETERS

-Path

Specifies the path or paths to the Gzip files to expand. To specify multiple paths, and include files in multiple locations, use commas to separate the paths. This Parameter accepts wildcard characters. Wildcard characters allow you to add all files in a directory to your archive file.

Type: String[]
Parameter Sets: PathDestination, Path
Aliases:

Required: True
Position: 0
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

-LiteralPath

Specifies the path or paths to the Gzip files to expand. Unlike the -Path Parameter, the value of -LiteralPath is used exactly as it's typed. No characters are interpreted as wildcards

Type: String[]
Parameter Sets: LiteralPathDestination, LiteralPath
Aliases: PSPath

Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-Destination

The destination path where to expand the Gzip file. The target folder is created if it does not exist.

Note

This parameter is Optional, if not used, this cmdlet outputs to the Success Stream.

Type: String
Parameter Sets: PathDestination, LiteralPathDestination
Aliases: DestinationPath

Required: True
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Encoding

Character encoding used when expanding the Gzip content. This parameter is only available when expanding to the Success Stream.

Note

The default encoding is utf8NoBOM.

Type: Encoding
Parameter Sets: Path, LiteralPath
Aliases:

Required: False
Position: Named
Default value: utf8NoBOM
Accept pipeline input: False
Accept wildcard characters: False

-Raw

Outputs the expanded file as a single string with newlines preserved. By default, newline characters in the expanded string are used as delimiters to separate the input into an array of strings.

Note

This parameter is only available when expanding to the Success Stream.

Type: SwitchParameter
Parameter Sets: Path, LiteralPath
Aliases:

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-PassThru

Outputs the object representing the expanded file.

Type: SwitchParameter
Parameter Sets: PathDestination, LiteralPathDestination
Aliases:

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-Force

The destination file gets overwritten if exists, otherwise created when this switch is used.

Note

If -Force and -Update are used together this cmdlet will append content to the destination file.

Type: SwitchParameter
Parameter Sets: PathDestination, LiteralPathDestination
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Update

Contents of the expanded file or files are appended to the destination path if exists, otherwise the destination is created.

Note

If -Force and -Update are used together this cmdlet will append content to the destination file.

Type: SwitchParameter
Parameter Sets: PathDestination, LiteralPathDestination
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

CommonParameters

This cmdlet supports the common parameters. For more information, see about_CommonParameters.

INPUTS

String

You can pipe paths to this cmdlet. Output from Get-ChildItem or Get-Item can be piped to this cmdlet.

OUTPUTS

String

This cmdlet outputs an array of string to the success stream when -Destination is not used and a single multi-line string when used with the -Raw switch.

None

This cmdlet produces no output when expanding to a file and -PassThru is not used.

FileInfo

When the -PassThru switch is used this cmdlet outputs the FileInfo instance representing the expanded file.
