unpack

NAME

unpack - expand files compressed with pack

SYNOPSIS

unpack [-cdfhlLnNrtvV19] [-S suffix] [file ...]

DESCRIPTION

The unpack(1) utility uncompresses files compressed with pack(1). It replaces the compressed files with their unpacked form. The specified file might or might not have the .z extension.

The file cannot be unpacked for one of the following reasons:

• It cannot be opened.
• It does not appear to have been compressed by pack(1).
• A file with the unpacked name already exists.
• The file name without the .z extension is more than {NAME_MAX} bytes long. This is possible if the packed file was brought from another system.

The options for unpack(1) are:

-c

Write on standard output; keep original files unchanged

-d

Decompress

-f

Force overwrite of output file and compress links

-h

Give this help

-l

List compressed-file contents

-L

Display software license

-n

Do not save or restore the original name and time stamp

-N

-q

Suppress all warnings

-r

Operate recursively on directories

-S .suf

Use suffix .suf on compressed files

-t

Test compressed file integrity

-v

-V

-1

Compress faster

-9

DIAGNOSTICS

The unpack(1) utility exits with status 0 on success, and >0 if an error occurred.

NOTES

This utility is actually a link to the gunzip(1) command (a copy of the binary on file allocation table (FAT) systems).
