NAME
lz - gunzips and shows a listing of a gzip'd tar'd archive
SYNOPSIS
lz fileDESCRIPTION
lz provides a listing of a gzip'd tar'd archive, that is a tar(1) archive compressed with the gzip(1) utility. It is not strictly necessary on Debian GNU/Linux, because the GNU tar(1) program provides the same capability with the commandtar -tzf file
but this utility is provided in the mtools package for other platforms and is retained here for completeness.
