Description

Lunzip is a decompressor for lzip files. It is written in C and its
small size makes it well suited for embedded devices or software
installers that need to decompress files but do not need compression
capabilities.

Lunzip replaces every file given in the command line with a decompressed
version of itself. Each decompressed file has the same modification
date, permissions, and, when possible, ownership as the corresponding
compressed file. Lunzip is able to read from some types of non regular
files if the "--stdout" option is specified.

Lunzip attempts to guess the name for the decompressed file from that of
the compressed file as follows:

filename.lz    becomes   filename
filename.tlz   becomes   filename.tar
anyothername   becomes   anyothername.out

If no file names are specified, lunzip decompresses from standard input
to standard output. In this case, lunzip will decline to read compressed
input from a terminal.

Lunzip will correctly decompress a file which is the concatenation of
two or more compressed files. The result is the concatenation of the
corresponding uncompressed files. Integrity testing of concatenated
compressed files is also supported.

The amount of memory required by lunzip to decompress a file is only a
few tens of KiB larger than the dictionary size used to compress that
file.
