'tar' interprets the first following argument (./filename-1.tar.gz
when staying with your terminology) as the value of the 'f' option,
that is, as the archive it should use.
All *other* arguments are interpreted as files *within* that archive,
which tar tries to find and unpack. Obivously, files by that name do
not exist within the first archive.
('xargs' fills up as many arguments as space-wise possible on one
command line.)
The simplest possible modification to make the command behave as you
intend is to tell 'xargs' to only write one argument per invocation:
find . -name "*.tar.gz" -print0 | xargs -0 -n 1 tar xzf
'xargs -n <foo>' tells xargs to only print <foo> arguments for each
execution; one in ourg case.
So long,
Joe
